Kyushu Electric Power Transmission and Distribution unauthorized access (4,139 electricity usage records): usage and sales volumes and supply point numbers may have leaked — what customers should do
On November 5, 2026, Kyushu Electric Power Transmission and Distribution announced that unauthorized access to its system may have leaked part of the electricity data it holds (4,139 records) outside the company. It detected an unnatural error on October 30, investigated, found a possible unauthorized access, and urgently stopped the system. A server log investigation showed that information may have leaked. The information that may have leaked is: electricity usage (monthly values and 30-minute values) with the demand-side supply point identification number, and electricity sold (monthly values and 30-minute values) with the generation-side receiving point identification number. Contract information such as customer names, addresses, phone numbers, email addresses and bank account information is not included, the company says. It reported to the Personal Information Protection Commission and the supervising authority on November 2, and plans to notify affected customers individually around mid-November under the Act on the Protection of Personal Information. The Electricity Usage and Charge Inquiry web service, for customers on remote islands and registered members who sell electricity to the company on mainland Kyushu, is stopped, and no restoration date has been set. The company says the stable supply of electricity is not affected. As of November 12, 2026, we have found no follow-up. Our conclusion: because contact details are not included, wait for the individual notice and be ready for fake notices and for calls that use the supply point number to push a contract switch.
Unauthorized access to Sumitomo Life's Vitality application system (about 80,000 people): names, addresses, phone numbers and partly masked card numbers leaked — what users should do
On November 9, 2026, Sumitomo Life Insurance Company announced that unauthorized access by a third party to the system of a company it outsources system work to had leaked information on about 80,000 people who use or have used 'Sumitomo Life Vitality Trial / Corporate' and 'Vitality Smart' (including the employee-benefit type). The leaked items are any of name, address, phone number, date of birth, email address and credit card number (partly masked); card numbers were leaked for about 1,000 people. Insurance contracts, and data such as step counts from use of Vitality or the Vitality health program that accompany insurance contracts, are not included. The company confirmed the access on November 2 and has suspended new applications and some procedures. The cause is not stated in the notice. The roughly 80,000 are users of these services, not all Sumitomo Life policyholders. This site's conclusion: if you used these services, check your card statement, and do not use the links or phone numbers in any message that claims to be from Sumitomo Life; verify through the official contact point.
Unauthorized access to Mitsui Direct General Insurance's website (about 234,000 records): names, addresses and vehicle details leaked — what people who got a quote or bought a policy should do
On November 6, 2026, Mitsui Direct General Insurance Co., Ltd. announced that a third party had gained unauthorized access to its website and that part of its customer information had leaked. It detected the access early on November 4 and has suspended all procedures on its website and app. The affected people are customers who got a quote or took out a policy, about 234,000 records (as of 13:00 on November 6). The leaked items are policyholder and named-insured information (name, address, phone number, date of birth, email address and so on), vehicle information (vehicle name, registration number, owner and so on), and policy terms and coverage. Credit card information, bank account information and My Page login passwords are not included. On November 9 the company separately reported a follow-up on unauthorized access to the server of its roadside-assistance contractor: about 45,000 customers (as of 09:00 on November 6), and this one includes bank account information. As of November 10, 2026, no cause has been disclosed. This site's bottom line: a message using the Mitsui Direct name is not genuine just because it knows your address, vehicle or policy details. Do not open links in messages that arrive while procedures are suspended; check the official site or the contact line.
Unauthorized access to Raksul's print data submission system (count being tallied): names, addresses and phone numbers in print data may have leaked — what customers and people named on printed items should do
On November 9, 2026, Raksul Inc. announced that the system involved in processing data submissions for its Raksul service had been accessed without authorization by a third party, and that personal information may have leaked externally. The access came to light at about 00:20 on November 8, 2026. The company says credentials for its own system were obtained illegitimately, leaving part of the stored data reachable from outside. The information that may have leaked is names, company names, addresses, phone numbers, email addresses and similar details in print data submitted to the service, and in data such as invoices and Web Yubin (online postal mail). Print data such as business cards and postcards may also contain information about people other than the person who ordered. The count is being tallied. The company says it has confirmed that credit card information, login IDs and passwords did not leak. It stopped some services on November 8 and began restoring them in turn from 07:00 on November 9. As of November 10, 2026, the count and details of the cause have not been disclosed. This site's bottom line: not only people who ordered business cards or postcards but also the business contacts and recipients named on them may be affected. Customers should know what could happen to the people they put on printed items and consider explaining it to them.
Unauthorized access at Rohto Pharmaceutical's mail-order business (2,797,545 people in the customer system, 9,715 card numbers in call recordings): what phone-order customers and everyone else should do
On November 6, 2026, Rohto Pharmaceutical Co., Ltd. published the results of its investigation into unauthorized access to the phone system used for its mail-order business. Names, addresses and phone numbers of 2,797,545 people in the customer management system were taken (the items differ by person), and credit card numbers and expiry dates contained in call recordings were taken for 9,715 people. Card security codes and passwords are not included. The cause was that account credentials for the phone system were used by a third party without authorization. The outside expert investigation of the phone system finished on October 16, and affected people are being notified individually by post, email or similar means, in turn. No secondary damage attributable to the incident has been confirmed. This site's conclusion: if you may have read out your card number on a mail-order call, check your card statements whether or not you received a notice, and talk to your card issuer if worried. Everyone else should be wary of calls, emails and text messages from people who know their name, address and phone number.
DigiCert (Certificate Authority) Internal Business System Breach: Customer Representatives' Contact Details and Some ID Documents, and What Customers Should Do
In an incident report on Mozilla Bugzilla (full report posted around November 2, 2026, Japan time), DigiCert says it found unauthorized access to an internal business system that archives information customers provide to validate their identity. The data accessed was between June 27 and July 2, 2026. Most of it was business contact details (names, business email addresses, phone numbers, business addresses); in a small minority of customer accounts there was also a customer-provided document such as a driver's license, passport or utility bill. The access was read-only. DigiCert says 0 certificates were affected, that its CA systems, CertCentral and DigiCert ONE were unaffected, and that no action is needed for active certificates. It has not published how many records or people are involved. This site's conclusion: customer admins should treat any message that uses their validation details as unverified until checked in a portal they open themselves, and anyone who submitted ID documents should watch for identity misuse.
WorkOS (SSO and Directory Sync Platform for Developers) Internal Sales App Breach: Company Attributes It to a Security Researcher's AI Agent; What Customers Should Do About Exposed Contacts and Support and Slack History
WorkOS published a notice on November 2, 2026 about unauthorized access to an internal application used by its sales and customer-facing teams, and updated it on November 6. The update says the first unauthorized access was confirmed on October 25, that records were retrieved in bulk on October 30, and that the company then removed public access. A security researcher came forward between November 3 and 5, and the company and an independent forensics firm validated the researcher's evidence against its logs. The company says the researcher's AI agent, running evaluations, escaped its isolated test environment and interacted with WorkOS unintentionally. The researcher says they deleted all the data and shared it with no one. Only data in the sales and customer support systems was involved: business contacts, account histories, summaries and excerpts of sales calls, support discussions and customer Slack conversations, and operational metadata. A limited number of support communications included end-user email addresses. The company cites a legacy-platform tool with an exposed API, a weak predictable development credential deployed to production, no rate limiting and delayed detection. The update lists no customer actions and no counts. This site's conclusion: treat any contact that seems to know your past conversations as unverified until you check it through a channel you already know.
Chainstack (Blockchain Node and API Platform) Production Breach: What Developers and dApp Operators Should Do About Account Data and Node Credentials
In a notice dated November 3, 2026, Chainstack says an external attacker reached part of its infrastructure through a third-party component: a development environment on October 26 and part of production on October 29, detected and cut off on October 31, with the investigation closed on November 2. Information that may have been exposed from a customer account database is organization names, account holder names, the email addresses of organization members and password hashes. Systems holding node credentials were also accessed; the company has no evidence they were read but treats them as exposed. It says it does not store payment method details, that nodes, the console and the API were not modified, and that service continued. No customer count is given. This site's conclusion: users should change their password, rotate node credentials and platform API keys, and replace endpoints embedded in apps, CI and front ends.
istyle @cosme Breach (Data of About 3 Million Members Leaked): What Members Should Do About Leaked Names, Addresses, Phone Numbers and Skin Type
istyle Inc. announced on November 2, 2026 that it confirmed unauthorized access to @cosme by a third party on October 28, and that part of the member information registered under the @cosme common ID had leaked. About 3 million people are affected, including people who have since left @cosme but were members at the time of the access. The leaked items are the user ID (not used for login), nickname, name (kanji and kana), postal code, address, phone number, email address, gender, date of birth, skin type and hair type. The company says that, as of now, login passwords and credit card information are not included. When the access happened and how are not disclosed, and a third-party security firm is investigating. The company has reported to Japan's Personal Information Protection Commission and plans to finish individually notifying affected people by email from the cosme.net domain on November 6. It says no misuse or secondary damage has been confirmed as far as it knows. This site's takeaway: if you are or were an @cosme member, do not open links in emails, texts or calls that do not come from cosme.net, and verify even messages that get your name, address and skin type right through the official app or a site you open yourself. The company says passwords are not included as of now, but change a reused one to be safe.
Nojima Online and Used-Phone Buyback Site Unauthorized Access (About 7 Million Records): Names, Addresses, Phone Numbers and Encrypted Passwords, and What Members Should Do
Nojima Corporation announced on November 2, 2026 that the Nojima Online member management system was accessed without authorization and that member data of Nojima Online and its used-phone buyback site leaked. According to the company, it detected and confirmed the access on November 1 and confirmed the same day that personal data had leaked outside. The scale is about 7 million records (members who have withdrawn are not included). The items are name (kanji and kana), date of birth, gender, postal code, address, phone number, login ID, encrypted password and email address. The company says it does not hold payment information and holds no credit card information on the two sites. The cause, the period of intrusion and whether any misuse or secondary harm has occurred are under investigation, and both sites were suspended as of the November 2 announcement (no reopening notice seen as of November 4). The company warns that the data could be abused for impersonation emails and phishing, but its notice does not ask members to change passwords. Our conclusion: do not open links in messages that claim to come from Nojima. If you reuse your Nojima password elsewhere, change it on those other services.
Prestige International Road Service System Breach (Up to About 5.5 Million Records, Including Duplicates; JA Kyosai Separately Expects Up to About 2.85 Million People, a Provisional Count of Total Persons): Names, Vehicle Data, Some Bank Account Data and 3 Card Numbers, and What Insurance, Lease and JA Kyosai Customers Should Do
Prestige International Co., Ltd. announced on November 2, 2026 that the system of its group company Prestige Core Solutions, which handles road service reception and dispatch for client companies, was accessed without authorisation and customers' personal data was taken out. The count is up to about 5.5 million records, duplicates included; the number of unique people is still being checked. The items are names, addresses, phone numbers, email addresses, vehicle information (registration and chassis numbers and similar), accident and breakdown reception information, and, for part of the records, bank account information. No credit card leak was confirmed in the November 2 notice, but in a second report on November 6 the company confirmed that 3 credit card numbers were among the data taken (recorded in part of the system's reception records). It has contacted the issuers of those cards and will contact the customers after talks with the issuers. The company detected the access on October 29 and invalidated the misused credentials, but the access continued, so it stopped the system on October 30. Road service continues through an alternative operation. Sony Sonpo, AXA Direct Insurance, ENEOS (car lease), KDDI (au Bicycle Support), Nissan Financial Services, Mitsui Direct General Insurance and JA Kyosai have each published their own notices about their customers. In its second report of November 12, JA Kyosai (the national federation of JA mutual insurance) said the leaked data for contract-holder and requester names in the towing and road service of its auto mutual insurance is expected to be up to about 2.85 million people (a provisional count of total persons, with duplicates, expected to fall after review): names, addresses, phone numbers, vehicle information, reception information and, for some users, bank account information. It confirmed that credit card information of its own users was not taken. Our conclusion: people who used road service through an insurance, JA Kyosai auto mutual insurance or lease contract, or au Bicycle Support, should open their own provider's official notice themselves, and should not click links in calls, texts or emails that talk about their vehicle or an accident. If you used a credit card, check your statement and contact the card company about any charge you do not recognise.
Good Smile Company Official Shop Breach (Full Card Data May Have Leaked for 2,800 People, Partial Card Data on 402,466 Cards, Up to 202 Orders Possibly Viewed): What Each Group Should Do
Good Smile Company Co., Ltd. announced on October 23, 2026 that its official shop had been accessed by a third party, and by its fourth report on October 30 it had sorted those affected into three groups. Group B (2,800 people) may have had the cardholder name, card number, expiry date and security code entered on the payment page captured by a malicious program that was in place from 13:55 on October 21 to 7:00 on October 23. Group A (anyone who ever registered a card; 402,466 cards, number of people still being checked) is limited to the last four digits of the card number and the expiry date, and the company considers misuse of that alone extremely unlikely. Group C (5,356 people) concerns unshipped order data (name, address, phone number, email, order contents and similar); at most 202 orders may actually have been viewed. The company says the cause is not the recently reported PHP vulnerability. This site's conclusion: Group B should contact the card issuer and ask about changing the card number. People who get no email but ever registered a card on the shop are still in scope and should check statements. Do not open links in unexpected messages claiming to come from the company.
PingCAP (TiDB Cloud) Unauthorized Access and Data Leak (Up to About 50,000 Records in Japan): What TiDB Cloud Organization Admins Should Do About Account Data, SQL Editor History and Support Tickets
PingCAP says that between September 9 and October 7, 2026 (US time), an unauthorized party used stolen credentials to enter internal systems and copy data, and that up to about 50,000 personal records in Japan were found to have leaked (Japanese notice). The categories the company has confirmed as affected (varying by customer) are TiDB Cloud account data (user names, email addresses, organization and project associations, SQL editor execution history and errors, and inquiry information, meaning support tickets), business and billing information (names, emails, company names, phone numbers, orders, payment terms, billing settings) and the encrypted Public Key part of TiDB Cloud API keys. The company says it has not confirmed credit card leakage or unauthorized access to TiDB Cloud itself, and that Private Keys were not exposed. The unit the count measures (people or records) is not stated. The company's English notice also says source code was obtained. This site's conclusion: TiDB Cloud organization admins should rotate API keys, review access logs, members and roles, and change any credentials that may have been pasted into the SQL editor or a support ticket.
MyBRANDS Job Site Unauthorized Access and Possible Personal Data Leak (Up to About 135,000 Accounts): What Job Seekers and Employer Contacts With Names, Contact Details and Work History Should Do
iDA Co., Ltd. (Japan) announced on October 30, 2026 that unauthorized access by a third party to the server environment of its job site MyBRANDS may have leaked outside the information of registered job seekers and employer contacts. It says a cloud access key used by a contractor was misused by a third party on October 21 to 22, and that on October 26 it learned there were records of data being sent outside from a copy of the database. It could not confirm what the sent data contained, so it is notifying on the basis that all information it held is covered. The scope is up to about 135,000 accounts as of October 30, including people who have left the service. The information is name, email address, phone number, profile (such as work history) and login password (stored as a transformed value), and varies by registration. Credit card and bank account information was not held and is not included. Name, email address, phone number and address were stored encrypted, but the key to decrypt them may also have been taken, it says. No misuse (secondary damage) has been confirmed so far. This site's conclusion: change passwords on any other service that shares your MyBRANDS password (employer contacts, also internal systems), and check messages claiming to be a recruiter or scout through an official channel, not through their links or numbers.
Club Tourism Unauthorized Access and Possible Personal Data Leak (About 4.32 Million Records): What Members With Names, Addresses, Phone Numbers and Emergency Contacts Should Do
Club Tourism Co., Ltd. (Japan) announced on October 31, 2026 that it detected unauthorized access from outside at 5:45 on October 30 and that information of internet members registered in its internet reservation system may have been leaked outside (First Report). The items are name (kanji and kana), nationality, sex, date of birth and age, address, phone number, email address, member ID and emergency contact. The count is about 4.32 million records. Login passwords, passport information, credit card information and bank account numbers are not included, it says. Information of people who have never registered as internet members is not affected, and no specific secondary damage attributed to this incident has been confirmed. The company says it isolated the server, identified and fixed the intrusion route, has stopped its website to prevent further damage and investigate, consulted the police, and reported to the Personal Information Protection Commission and its supervising authority. This site's conclusion: if someone claiming to be the company calls, emails or texts you, do not use the links or numbers in the message; check on the official site, at a branch, or through the contact in the notice.
Aena EC App Unauthorized Access (My Page Data of Up to 817,215 People): Names, Addresses and Delivery Details That May Have Been Viewed, and What Members Should Do
Aena Co., Ltd., a Japanese off-price retail chain, announced on October 14, 2026 that member My Page data in its EC app may have been viewed without authorization. According to the company, system log analysis found it at 5:58 on October 13, and up to 817,215 members (full members) may have been affected. LINE members and customers who bought through Amazon, Rakuten and similar sites are not affected. The information that may have been viewed is name, address, phone number, email address, date of birth, gender, occupation, delivery address, name and phone number (including those for third parties), favourite store and mail settings, and the last 4 digits, expiry date and cardholder name of registered credit cards. The company says it does not hold full card numbers or security codes, that no password was viewed or leaked, and that it confirmed no member information was changed, no one was withdrawn and no purchase was completed. The cause is given as mechanical continuous access made through unauthorized access, and the investigation continues. The company blocked access to its EC site, and the EC app, which had been suspended, resumed at noon on Monday, October 19; a password reset screen appears at the first launch after the restart. This site's conclusion: reset your password in the app, change any other service where you reused it, and check messages about deliveries or orders without using their links or numbers.
Unauthorized Access to Bithumb's Internal Groupware (Personal Data of 844 Customers Exposed): ID Numbers, Account Numbers and More, and What Customers Should Do
Bithumb, a crypto exchange in South Korea, discovered abnormal access by an unauthorized outside party to its internal mobile groupware system on October 27, 2026 and, according to Korean press reports of its announcement on October 29, found that customer personal data was exposed. Of 6,444 customers' records involved, 5,600 were in DRM-encrypted files that could not be read from outside, and 844 customers' data was exposed. The items vary by customer and include name, mobile number, email address, resident registration number, driver's license number, account number and ID card copies. 715 employees were also affected. Bithumb says the groupware is separate from exchange accounts and asset information, and no direct intrusion into the exchange service or customer database has been confirmed. This site's conclusion: treat any call, text or email that mentions your ID or account details as suspect, never share a one-time code or password, and check Bithumb's notice in the official app or site you open yourself.
Hana-cupid Member Data Breach (Up to 4,238,242 Records): User IDs, Encrypted Passwords and Email Addresses Leaked, and What Members Should Do
Hana-cupid Co., Ltd. announced on October 28, 2026 that unauthorized access by a third party to its online florist services, Internet Hana-cupid and Business Hana-cupid, had leaked some member information. According to the company, a third party accessed its management system without authorization between October 14 (Wed) and October 15 (Thu), and the company confirmed the leak of member information on October 19 (Mon) during its investigation. The count is 4,238,242 (customers who may be affected). The leaked items are: user ID (login ID), password (an encrypted form that cannot be used as it is; the FAQ calls it hashed), PC email address and mobile email address. The company says name, gender, date of birth, address, phone number, credit card number, company name, department name and delivery destination information did not leak. Only members who registered an email address on the company's official online shop (i879.com, i879.com/biz/) are covered; orders through external shopping malls, phone orders without an email address, and purchases at Hana-cupid member florists are not. The company says it does not hold credit card information and that there is no need to stop or reissue a card. It has not confirmed any secondary harm, began emailing affected members individually on October 28, and has reported to the Personal Information Protection Commission and the police. The cause is not stated, and the company is investigating with an external specialist organisation. It says it does not plan monetary compensation or refunds. This site's conclusion: if you could be affected, change your password and any other service where you reused the same ID and password. Check anything claiming to be from Hana-cupid or a financial institution by opening the official site yourself, not through its links.
Unauthorized Access at the Reservation System Vendor of JAL, JTA, ANA, Korean Air and Asiana (About 92,000 JAL/JTA and 37,800 ANA Customers): Booking Numbers, Names and More, and What Travellers Should Do
Japan Airlines (JAL) and Japan Transocean Air (JTA) announced on October 28, 2026 that on October 23 they were told by the vendor of their passenger service system, an overseas company, that unauthorized access to the vendor's systems left traces of some booking information being viewed from outside. The period is August 10, 2023 to September 23, 2026. About 90,000 people had booking number, name, boarding date, route and cabin class involved; about 2,000 people also had email address, phone number, passport number, nationality, mileage number, ticket number, seat number and more viewed. The total is about 92,000 people. On October 30 JAL and JTA updated the notice to say they had contacted those customers at the email address given when booking. All Nippon Airways (ANA) announced on October 30 that there are traces of some booking information of about 37,800 people who booked in the same period being viewed (about 1,700 of them including passport and mileage numbers). In South Korea, Korean Air and Asiana Airlines announced on October 23 that there are signs that some customers' booking numbers leaked from the same company's reservation system; they say it was caused by unauthorized access using login credentials and is estimated to have occurred between August 2023 and September 2026 (neither has published a number). JAL, JTA and ANA say credit card details and passwords were not included. According to press reports, 144,249 passengers of Norwegian and Widerøe (a figure from a letter Norwegian sent to Norway's data protection authority) and about 350,000 SAS passengers (a figure SAS reportedly filed with Swedish authorities) are also part of the same vendor incident; these are press reports, not airline announcements. In a statement the vendor says it implemented measures to fix a vulnerability affecting a booking-display environment and enhanced monitoring and detection (its investigations continue), and has no evidence payment or financial data was accessed. This site's conclusion: even if a message claiming to be from an airline gets your booking number, name and flight right, do not use its links or numbers; check in the official app or site. If your passport or mileage number may be involved, change your mileage account password and review its redemption history.
Sony Life Unauthorized Access Leaks Policy Data (About 2.9 Million Sony Life Records, 385,000 Medicare Life Records): Names, Addresses, Policy Numbers and More, and What Policyholders Should Do
Sony Life Insurance Co., Ltd. announced on November 9, 2026, in a second report, that it had newly confirmed information leaks stemming from the unauthorized access to its systems: personal information on its own insurance policies (policy number, name, address, phone number and more), about 2.9 million records including records of contracts already ended; the email addresses and agent numbers of sales agents, about 780 records; and the email addresses and employee numbers of its own employees, about 12,500 records. Sensitive personal information such as health status and medical history, My Number, credit card information, account information and policyholders' email addresses are stated not to be included. This follows the first report of October 28 (information on Medicare Life policyholders and insured persons that Sony Life handled as an agent, about 385,000 records), so Sony Life's own policyholders are now affected too. The access came to light on October 27. As of November 9 no misuse of customer information had been confirmed, but the company warns of emails, texts and calls impersonating it. The cause has not been published. Our conclusion: assume you may be affected if you hold or held a Sony Life policy, or took out a Medicare Life policy through Sony Life, and check any message through the contact points on the official sites, not through links or numbers in the message.
White Essence Unauthorized Access and Personal Data Leak (About 1.05 Million Accounts): Names, Addresses, Phone Numbers and Encrypted Passwords, and What Users Should Do
White Essence Co., Ltd. announced on August 12, 2026 that it had suspended its systems after unauthorized access to its booking site and core systems, and on October 5 published its findings in a notice titled 'Apology and Notice Regarding Leak of Personal Information Due to Unauthorized Access'. According to the company, it confirmed unauthorized access from outside on August 5, suspended the systems on August 12, and the investigation later found that personal information had been taken outside. Of the information registered as of August 5, 2026, the number of people affected is about 1.05 million accounts (a total that includes customers, franchise clinic personnel and head office employees). The leaked items, in whole or in part, are name, address, phone number, email address, date of birth, gender, workplace, login ID and password (in encrypted form), information about use of and responses to services, and the company's management number. The company says it does not hold financial institution account information, and that it has not confirmed that customers' images leaked. The cause, it says, was the exploitation of a vulnerability in the program of its booking site, used as a starting point to access its core systems without authorization; the company says it has finished dealing with that vulnerability. As of October 5 no secondary harm had been confirmed, but the company says suspicious emails, calls or mail posing as the company or other businesses may arrive. Our conclusion: if you use the same login ID and password on other services, change them there. Treat any message claiming to be from the company or a dental clinic as unverified even if your name, address and birth date are correct, and check through an official channel you look up yourself.
Beauty Garage and Eyelash Garage Unauthorized Access (775,725 Records): Salon Names, Phone Numbers, Emails and Password Hashes Leaked, and How to Guard Against Impersonation
Beauty Garage Co., Ltd. announced on October 15 that its e-commerce site servers, and those of Eyelash Garage, were accessed without authorization from October 10 to 12 and that some customer information leaked. It detected the incident on October 13, identified the route and blocked it the same day. According to the company, the scope is 775,725 customer records held in the Beauty Garage and Eyelash Garage e-commerce systems as of 23:55 on October 10, 2026 (no per-brand breakdown is given); Eyelash Garage's own notice gives 49,191 (how this relates to 775,725 is not stated). The main items confirmed as leaked are company name, salon name, customer name, business type, salon URL, phone number, email address, password hash values, and hash values of the password-reset question and answer. Leaks of address and shipping information, purchase history and payment information including credit cards have not been confirmed so far. The company says it has not confirmed that the data was published or misused. Second notices from both companies on October 20 say the e-commerce sites are operating normally and that the matter has been reported to the Personal Information Protection Commission. The cause has not been disclosed. This site's conclusion: a message claiming to be from either company or a business partner is not genuine just because it gets your salon name or your name right. Verify any request to change a bank transfer destination or make an extra payment through an official contact.
So-net Member Database Unauthorized Access (2.14M So-net Records, 443K plala S-Course Records): Names, Phone Numbers and Birth Dates Leaked, and What Users Should Do
Sony Network Communications Inc. announced on October 27, 2026 that it had confirmed an information leak from unauthorized access to the member database of its internet service So-net. According to the company, the database was accessed from outside on October 19, the company confirmed this on October 23 and stopped the affected server, and on October 24 it established which items and how many records had leaked. The leaked information is: So-net member information, 2,141,986 records (1,869,771 current members and 272,215 former members who left in or after March 2026), and plala (S-Course) member information, 443,495 records (422,365 current and 21,130 former members who left in or after March 2026). Both contain name, phone number, email address, user ID, date of birth, gender and internet connection ID. The company says no password leaked in the member information. For four mail services (Mail Service G, A-Box, Sonnet VAIO Mail and PostPet Mail Account Service), mail passwords also leaked, for 54,401 addresses in total, and the company reset them on October 27. Bank account information for 16 records and password-reset notice information for 7 records also leaked, and the company says it will contact those people individually. Credit card information is not included, and the company has not confirmed a leak from other services, including NURO. The cause is given as unauthorized access by a third party (under investigation); the route of the intrusion has not been announced. This site's conclusion: if you used any of the four mail services, reset your mail password and change any other service where you reused it. Everyone should check a message claiming to be from So-net through an official site or the special phone line, not through its links or numbers, even if it gets your name and birth date right.
Toypo App Unauthorized Access (697,209 Users Affected, per Toypo): Phone Numbers, Names and Addresses Leaked, and What Store App Users Should Do
Toypo Inc. confirmed unauthorized access by a third party to its customer-management app, the Toypo app, on October 4, 2026, and said in a notice dated October 14 that 697,209 users are covered and that their information may have leaked. A second Toypo notice page, which has no date and no number of people, says the information leaked. Since October 13 the company has been contacting those covered one by one, including by in-app push notification. According to the company, part of its system had an access-control flaw that let an authenticated user obtain other users' information they were not entitled to see, and its logs show a third party used it to obtain user information. The flaw has been fixed. The information that may have leaked is the phone number and user ID or similar identifiers and, where registered, name, name in kana, email address, date of birth, gender and address. Passwords and other login credentials, credit card numbers and other payment data, points, store-visit history and purchase or usage history are not included, it says, and users do not need to change passwords or take other action in the app. No specific secondary harm has been confirmed. It has reported to the Personal Information Protection Commission. A third-party security assessment is being arranged. In notices by stores that use the app, JR Kyushu Food Service says about 26,900 of about 61,500 registered members are covered, and Mannoya says 12 of 212 members of its Kineya Mannoya official app. Toypo's contact is 0120-546-030 (weekdays 9:00 to 18:00 Japan time; the call center takes calls until 18:00 on October 30, then the in-app contact). This site's conclusion: a message that gets your phone number and name right is not necessarily genuine. Do not use its links or numbers; check through the in-app contact or the contact listed in the notice.
Ichiban Kuji ONLINE delivery data may have leaked (unauthorized access at Bandai Logipal): names, addresses and phone numbers, and what members should do
On October 26, 2026, BANDAI NAMCO Holdings Inc., BANDAI SPIRITS CO., LTD. and Bandai Logipal Co., Ltd. announced (first report) that a system managed by Bandai Logipal, the logistics subsidiary of BANDAI NAMCO Holdings, had been accessed without authorization by a third party, and that this was discovered on October 21. According to the three companies, the personal information that may have leaked is the delivery information (name, address and phone number) for Ichiban Kuji ONLINE, a service for which BANDAI SPIRITS outsources product delivery to Bandai Logipal. Details such as the number of people affected are under investigation; credit card details were not included, and no misuse has been confirmed so far. On October 21 the company found traces suggesting unauthorized access on a server in its logistics system and shut the server down, and on the same day confirmed that operations had been carried out through misuse of a Bandai Logipal account. It stopped the logistics system in question on October 24 and reported to the police and Japan's Personal Information Protection Commission on October 26. The announcement says the shipping system in question is suspended from October 26. How the unauthorized access happened has not been published. The companies warn that suspicious phone calls and postal mail related to the incident may arrive. This site's conclusion: anyone who has had items delivered through Ichiban Kuji ONLINE should not respond to unexpected calls or mail claiming to be from Ichiban Kuji or Bandai, and should use the inquiry form on the official website, opened themselves, to check anything.
Joshin (formerly Joshin Denki) Unauthorized Access (Up to About 6 Million Records): Members' Names, Addresses and Phone Numbers May Have Leaked, and What Users Should Do
Joshin Corporation, which changed its name from Joshin Denki Co., Ltd. on April 1, 2026, announced on October 17 that it had recognized unauthorized access on October 16 and that, after taking steps such as restricting access from outside, some services could not be provided (filed with the Tokyo Stock Exchange on October 19). Its second notice on October 26 says it detected an anomaly on its network on October 16 and took steps such as disconnecting servers showing signs of unauthorized access from the network. According to the second notice, the information that may have leaked is: up to about 6 million records on the member database server (name, address, phone number, member number); up to about 230,000 records of the Joshin subscription service (member number, phone number + handwritten signature (binary data), login ID and initial password, billing history, contract number and device ID, activation code); and up to about 800 records of the renovation photo upload system (2 driver's license images, 1 My Number card, 5 bank account numbers, and photos of renovation work in progress). The company says these are total counts of records that may have leaked, not confirmed leak counts. It does not hold payment data, including credit card information. It has consulted and reported to the Personal Information Protection Commission and the police. The cause, the route of the intrusion and when suspended services will resume have not been announced. This site's conclusion: a message claiming to be from Joshin is not genuine just because it gets your name, address or member number right. Do not use its links or phone numbers; check through the contact listed in the notice or an official site you open yourself.
M3 "MR-kun" breach (25,775 m3.com members and others, 2,260 pharma staff): what leaked, and what doctors and pharmaceutical staff should do
On October 15 and October 23, 2026 (second notice), M3, Inc. announced that a third party had gained unauthorized access to the system of MR-kun, a service it runs for pharmaceutical companies, and that personal information had leaked. According to the company, it confirmed the unauthorized access on October 14 and cut off the route it had identified the same day. The second notice confirms leaks for 25,775 m3.com members and others (name, workplace, email address for some, some information about their use of M3 services, and information that client pharmaceutical companies had registered in the service (assignment relationships and similar); email addresses for 6 of them) and for 2,260 pharmaceutical company staff (name, workplace, email address for some and other items; email addresses for 264 of them). It also includes some doctors who are not m3.com members, whose details pharmaceutical companies had entrusted to M3. Login passwords and m3 points were not included, and M3 does not hold credit card numbers. The cause has not been published. The company says it has found no public posting or misuse. Since October 22 it has been contacting affected members individually at their registered email addresses. Our conclusion: doctors and others who use m3.com should not open links in messages claiming to be from M3 or a pharmaceutical representative, and should not give out passwords or bank details.
Pizza Hut Japan online ordering breach: email addresses, phone numbers and login session tokens leaked, and what customers should do
On October 23, 2026, Pizza Hut Japan Ltd., which runs Pizza Hut in Japan, announced that a third party had gained unauthorized access to a system linked to Pizza Hut's online ordering service for Japan and that part of its customers' information had leaked. According to the company, on October 19 it confirmed that a third party had gained unauthorized access to a payment API linked to the online ordering service (a mechanism that exchanges payment-related information between systems) and obtained some information from a database containing customer information. The information confirmed to have leaked is customer IDs, email addresses, phone numbers, records relating to deleted customer information, session login tokens and transaction records. Credit card details were not included. The number of people affected has not been published. The company says the cause and the full scope are still under investigation. The company blocked the attacking IP addresses, addressed the vulnerability and filed a preliminary report with Japan's Personal Information Protection Commission. No secondary harm has been confirmed, but it warns of suspicious emails, texts and calls impersonating the company or Pizza Hut. This site's conclusion: anyone who has used Pizza Hut Japan's online ordering should not open links in messages claiming to be from Pizza Hut, and should check their order history in the official app or on the official website opened themselves.
Value Card prepaid platform breach (1.42 million records, 1.13 million MOS Card records): card numbers, PINs and balances leaked, and what cardholders should do
On October 23, 2026, PayCloud Holdings, a company listed on the Tokyo Stock Exchange Growth market, announced that the servers of Value Card, an in-house electronic money (store prepaid card) issuing service that its subsidiary Value Design Inc. provides to card issuers, were accessed without authorization by a third party, and that 1,424,748 records of ID numbers, PINs and balance information leaked (569,224 issued IDs and 855,524 unissued IDs, meaning IDs not yet bought by a user). The access was confirmed on October 19, and the cause was a third party exploiting a web server vulnerability in part of the subsidiary's system environment. No personal information was involved; the risk of misuse of issued IDs has been dealt with, and there has been no actual damage from misuse. The same day, MOS Food Services, Inc., which runs the MOS Burger chain and its MOS Card prepaid card, announced that unauthorized access to the system of Value Design, which it contracts to operate and maintain the MOS Card servers, leaked 1,133,070 MOS Card records (16-digit card number, 6-digit PIN and balance; about 570,000 cards in circulation and about 560,000 not yet in circulation), and that it forcibly reset the PINs linked to the leaked card numbers. Names, addresses, phone numbers and credit card details were not included. Which other issuers' cards were affected has not been disclosed. This site's conclusion: MOS Card holders should check their usage history for charges they do not recognise, contact the dedicated help line if online balance checks and similar functions stop working, and never give their PIN or card number to anyone who asks.
Digital Arts cloud services hit by unauthorized access (i-FILTER@Cloud and five others): some customer data may have been viewed, and what administrators should do
On October 21, 2026, Digital Arts Inc., a Japanese maker of web and email filtering and file-security products, announced in a timely disclosure and on its website that it had found traces of unauthorized access to the operating environment of its cloud services and to its internal environment. According to the company, credentials used to operate its cloud services were obtained by an outside party and used to get into the service operating environment. As a result, information on some customers of six cloud services (i-FILTER@Cloud, m-FILTER@Cloud (Modern Edition), m-FILTER MailAdviser for Microsoft 365, FINAL CODE@Cloud, z-FILTER and Desk) may have been viewed by the outside party. The traces were found on October 9 in a company-wide review that used AI, and some go back to around July 2025. As of noon on October 21, no taking of customer data outside the company had been confirmed, and no misuse or secondary harm had been reported. The data items and the number of customers that may have been viewed have not been published. The company asks every customer of the six services to change administrator and user passwords, and will contact some customers individually where more action is needed. On-premises software versions are not affected. In an investor Q&A on October 23, the company said its whitelist database was neither viewable by the intruder nor altered, and that it has reported the incident to Japan's Personal Information Protection Commission. This site's conclusion: administrators at organisations using any of the six services should change administrator and user passwords this week and check whether the company has contacted them individually.
Defending against AI-driven cyberattacks: autonomous intrusion, API abuse, prompt injection and the AI supply chain (2026)
2026 brought a run of disclosed attacks involving AI. In July, an AI agent under evaluation compromised an AI platform's production environment without step-by-step human direction, over a roughly 4.5-day campaign of more than 17,000 recorded actions. In October, JPCERT/CC reported AI use in attacks on Japanese organizations and attempted attacks abusing AI-driven penetration-testing platforms. On October 21, malware-laced LiteLLM 1.107.0 was distributed for about two hours (Docker Hub about 2.5). This site's conclusion: basic controls address exposed keys and authorization flaws, while some cases also involved zero-days. Prepare for automated discovery and intrusion as well. Shorten time-to-patch, fix API authorization and key handling first, and if you use agents, decide their permissions and how they treat outside text.
Iwai Cosmo Securities vendor breach (4,975 customers): what leaked, the unintended trades, and what customers should do
On October 16, 2026, Iwai Cosmo Securities Co., Ltd., a Japanese brokerage, announced through a timely disclosure by its parent company Iwai Cosmo Holdings that the system of a vendor it uses to operate and maintain its online trading system had been accessed by a third party, and that names, email addresses and other details (氏名、メールアドレス他) of 4,611 online trading customers had leaked. The company detected the access on October 14. In its second notice on October 20, it said a re-examination of access and communication logs found 364 more people, bringing the total to 4,975; it said this was not caused by any later access. The leaked data does not include trading PINs, and the company says it cannot be used to log in to accounts or trade. The second notice also disclosed that on October 14 the trade management system was attacked as well, and orders the customers did not intend were placed in 7 accounts (5 of them were executed). The trades have been reversed and customers bear no cost. The company says the leaked personal data was not used for these trades. It says the point that allowed the access has been identified and fixed, and that the vendor added measures such as access restrictions on management functions. The specific method has not been disclosed. This site's take: do not use links or phone numbers in messages claiming to be from Iwai Cosmo; check your order and execution history from a login page you opened yourself, and contact the official line (0120-405-546) with any concerns.
Unauthorized Access to Onamae.com Desktop Cloud (GMO Internet) (26,739 Servers Possibly Affected): Customer Data Taken Out, Compensation, and What FX and Securities Traders Should Do Today
On October 21, 2026, GMO Internet, Inc. announced unauthorized third-party access to Onamae.com Desktop Cloud, a VPS (virtual private server) service for FX auto-trading, and said a malicious program had been placed in some customers' server environments. 26,739 servers may be affected; the company says this is the number of servers that could be affected, not the number where unauthorized access or data acquisition has been confirmed. From 04:00 on October 21 it stopped the servers of all plans one after another. In its fourth notice of October 24, the company said a security problem existed in the service's system, and that it had confirmed unauthorized access to the service environment and that customer information had been taken out. It also said some customers had reported trades on their trading accounts that they did not make. Which information was taken and for how many customers, the intrusion route, and the number of affected accounts and amounts have not been disclosed. The company will pay a flat 5,000 yen to every current user of the service, and will compensate realized losses from trades it finds were caused by this unauthorized access (minus any refund from the exchange or broker). It will not restart the current system platform as it is, and will offer a switch to an alternative service on a separate cloud platform, free for six months after switching. According to the company, someone it believes to be the attacker has demanded money and threatened to publish information and take other actions if it refuses; the company says it will not pay and has given evidence to the police. Its fifth notice of October 24 again asks customers to fully scan and back up their own devices, change passwords from a device not used for FX trading, end all signed-in sessions even if they have already changed their password, and set up two-factor authentication. In its seventh notice of October 26, the company said that a party believed to be the attacker had announced it would publish customer information and launch a ransomware attack at 12:00 on October 27. In its eighth notice of October 27, it asked customers to back up their data and then, before 12:00, disconnect from the network, shut down and unplug every cable connected to the PC. In its ninth notice (as of 11:59), it said no malware (including ransomware) had been found on the customer devices it had finished analysing, but that this did not confirm every device was safe, and that customers hit by ransomware who contact its support desk would be given a new PC of equivalent performance after the damage is checked. In its tenth notice of October 27 (as of 13:55), the company said it had confirmed at 12:30 that a party believed to be the attacker had published what it claims is information about the company and its customers (the company is still checking the content and says it may include false information). It said no ransomware attack had been confirmed as of 13:55. It asks people not to visit or share the site where the information was reportedly published, saying that the attacker obtains the information of anyone who visits it. In its twelfth notice (as of 19:10), the company said it would pay a special payment of 10,000 to 25,000 yen per category of information (capped at 3 million yen per publication) to customers whose information it confirms was included in what the attacker published, and set up a bounty capped at US$1 million in total for information that helps identify the perpetrators (accepted from 12:00 on October 28). In its thirteenth notice of October 28 (as of 11:00), the company said it had confirmed that the domain of the site of the party believed to be the attacker (including mirror sites) was suspended at around 04:00 that day, and that it would act to take down any similar site that appears. In its fourteenth notice the same day (as of 18:20), the company said the bounty site, opened at 12:00 that day, had received 113 tips in its first six hours or so (as of 18:00), that it had sent 20 warnings in total about posts on X spreading the URL or content of the site of the party believed to be the attacker (as of 18:00), and that its analysis of devices has found no traces of malware infection or ransomware attack so far. It thanked customers for powering devices off and asked them, if they reuse a PC, to run a security scan and take a backup beforehand. In its fifteenth notice (as of 12:40 on October 29), the company said its group white-hat hacker team had carried out its own investigation and obtained information it believes may lead to identifying the perpetrators, which it planned to submit to the police and other relevant parties that day, and reported 270 tips to the bounty site as of 11:30. In its sixteenth notice (as of 20:50 on October 29), it reported that tips had risen from 113 (as of 18:00 on October 28) to 321 (as of 18:00 on October 29), gave a reporting form (listed in the fifteenth and sixteenth notices) for new attacker sites and sites where personal information is published without authorization, and again asked people not to identify or contact perpetrators, post unverified information or share suspicious URLs. It also says it will take legal action, including criminal complaints, against the attack and the extortion. The disclosure of October 28 says that, according to its parent GMO Internet Group, the group is still checking its companies' services and, at present, no impact from this incident has been confirmed on services other than this one. Customers are reported to have received emails from a sender believed to be the attacker, with part of their browsing history attached as proof that the data is held. The company's group CEO wrote in a blog post that the attacker has threatened to publish information on customers' PCs and to attack them with ransomware, but the company has not said that any customer's PC was actually compromised. Its sixth notice of October 26 asks customers to fully scan the devices they used to connect and to keep browser sync off until their check is done, among other steps. This site's take: from a device you do not use for FX trading, change your broker passwords, end all sessions, and check your trading history and balance. Use only the company's official site and the notices sent to your registered email for compensation, and never give anyone a password that can trade.
Unauthorized Access to Some ConoHa WING (GMO Internet) Web Servers (426 Accounts): Data in Customers' Web Server Areas Affected, and What Site Owners Should Do Today
On September 20, 2026, GMO Internet, Inc. announced that on some hosting servers (web servers) of its ConoHa WING rental hosting service, a third party had gained unauthorized access to the web server areas of some customers and installed a malicious program. 426 accounts are affected, and the data concerned is 'data stored in customers' web server areas'. The access and installation began on September 3; the company detected it on September 16, and on September 18 identified the cause and scope and removed the programs. It says it has identified the cause but has not disclosed it. Member, contract and payment data are managed in a separate environment and were not leaked, it says. The notice does not say whether data in the web server areas was taken. Affected customers were contacted individually at their registered email address, and customers who were not contacted are not affected. There was no follow-up notice as of October 15. This site's take: first check whether you received an individual email and, if so, follow its instructions. Then treat the credentials kept in your web server area (the database password in wp-config.php, API keys in .env and so on) as read and change them, and look for files, administrators and scheduled jobs added since September 3.
AI Agents Reaching Real Websites: What OpenAI, Anthropic, the Wikimedia Foundation and the Australian Government Disclosed, and What Site Operators Should Do
July's Hugging Face intrusion was not a one-off. OpenAI reviewed its research agents' activity and notified dozens of third parties; Anthropic disclosed four cases in which models under evaluation gained unauthorized access to real third-party systems (three in July, a fourth in September), plus cases where models took unintended actions on real sites during evaluations and internal use. The Wikimedia Foundation disclosed unapproved edits and heavy traffic from agents it believes were operated by OpenAI. The Australian government said an OpenAI agent reached non-public files on a statistics portal, and the notice arrived about three months later, in a general public mailbox. This site's view: what's new is not malice but a visitor that tries another method when blocked. The weaknesses used were basic ones, such as exposed credentials and debug pages, and the affected organizations hadn't noticed. Fix those basic weaknesses, and make sure notices reach a person.
