Burger King Japan disclosed a breach exposing 11.18 million app users’ personal data after attackers accessed its membership system in early October. Burger King Japan has disclosed a data breach that exposed the personal information of approximately 11.18 million official app members. Burger King Japan, the company operating the fast-food chain in the country, said attackers accessed the system managing customer membership information between October 2 and October 7, 2026. The company disclosed the incident on October 15, after discovering the data leak two days earlier. In its official notice published on October 15, the company confirmed the unauthorized access and apologized to affected customers. The announcement doesn’t identify the attackers or explain how they gained access. BK Japan says it’s working with external security specialists to determine the cause. “We have confirmed that customer membership information from the official app has been leaked externally following unauthorized access by a third party.” reads the data breach notification. The compromised data includes membership IDs, email addresses, names in Japanese characters and kana, phone numbers, dates of birth, gender, prefecture of residence, and membership registration type. The exposed information also indicates whether a customer has a mobile ordering history and whether their email address has been verified. These details can be useful to criminals even without payment data or passwords. Attackers can use them to craft convincing phishing emails, text messages, or phone calls that refer to a customer’s real identity and relationship with Burger King. A message that includes a person’s name, phone number, and other accurate details may look far more credible than a generic scam. Burger King Japan confirmed it does not store credit card numbers and found no evidence that passwords were exposed, with no confirmed cases of fraud so far. However, these factors do not completely rule out the risk of future misuse. According to the company, unauthorized access took place from October 2 through October 7, and the leak was confirmed on October 13. BK Japan says it blocked access from the source of the unauthorized communications as soon as it became aware of the incident. The company has also introduced temporary countermeasures, established an incident response team, and reported the breach to Japan’s Personal Information Protection Commission. It says permanent security improvements, further investigation with external specialists, and email notifications to affected customers are ongoing. “At present, we have confirmed that the unauthorized access was carried out by a third party.” continues the notification. The company has not yet disclosed the precise circumstances that made the intrusion possible, and the investigation is continuing. Until more details emerge, it’s too early to draw conclusions about the initial access vector or attribute the attack to a particular threat actor. Large-scale data breaches create long-lasting risks for follow-on attacks, as criminals can use stolen details for phishing, impersonation, and highly convincing scams. BK Japan urges customers to stay vigilant against fraudulent emails, texts, and calls, warning them never to click unverified links or share sensitive credentials. The core danger is that attackers no longer need network access to cause harm; they can leverage existing stolen data to target customers directly through social engineering. “Please do not access URLs, open attachments, or enter membership information or passwords if you receive a suspicious communication.” concludes the report.

Burger King Japan, the Japanese subsidiary of global fast-food giant Burger King, disclosed a major data breach after attackers accessed a server containing 11.18 million customer records. Founded in 1953 in Florida, Burger King is now a multinational fast-food chain with nearly 20,000 locations worldwide, including 350 in Japan. In a Thursday press release, Burger King Japan said it concluded a follow-up investigation on October 13 and apologized to customers whose data was stolen in early October and leaked online. The breached servers stored the personal information for users of the company's official smartphone app, including their names, dates of birth, gender, email addresses, phone numbers, and order history. "We identified a potential unauthorized third-party access to the system that manages member information for our official app and conducted an investigation," Burger King Japan said.
The regulated utility company CenterPoint Energy says a data breach exposed the personal information of more than 1 million people in Texas. CenterPoint Energy is a regulated utility company used to deliver natural gas and electricity infrastructure, maintain power grids and pipelines, and restore service across parts of Texas, Indiana, Ohio, and Minnesota. The organization disclosed a data breach affecting more than 1 million people in Texas. This week, CenterPoint Energy told the Texas Attorney General’s Office that the breach affected 1,062,060 Texas residents. The company does not appear to have notified the affected individuals by letter. “More than one million Texans were affected by a CenterPoint Energy data breach that compromised sensitive personal information, according to newly published information from the Texas Attorney General’s Office.” reported the broadcast Click2Huston. “The state’s data breach database lists 1,062,060 Texans as being affected. The information involved includes customers’ names, addresses, Social Security information and driver’s-license numbers.” Days before the first disclosure, on September 12, a threat actor using the alias “4d722e4d656f77” claimed on a cybercrime forum to have extracted roughly 7.49 million customer records from CenterPoint Energy. “In September 2026, CenterPoint Energy, Inc. (the “Company”) became aware of an online post by a third party claiming to have obtained a data set containing certain of the Company’s customer information.” reads the FORM 8-K report filed with SEC.”While the investigation remains ongoing, the Company has determined that an unauthorized third party obtained personal information relating to a portion of the Company’s customers through one of the Company’s external facing systems (the “Incident”).” The hacker claimed the theft of names, phone numbers, service and billing addresses, account numbers, billing amounts, payment status, and partial Social Security numbers. He offered a 2.5 GB archive for download. The attacker warned that “next time we won’t simply pull data, we’ll start attacking the main infrastructure,” a line that reads well on a forum but should still be taken seriously by any critical infrastructure operator. The attackers claimed they stole over the records through an API they say lacked proper WAF protection, rate limiting, and authentication. They also claimed the company tried to stop the data dump only after millions of records had been extracted. “CenterPoint Energy continues to actively investigate the cybersecurity incident disclosed last month. Upon learning of the issue, CenterPoint activated our incident response procedures and engaged external cybersecurity, forensic, and legal advisors to assist with the investigation.” a spokesperson for CenterPoint said on Wednesday. “We continue to work with third-party experts to assess the scope of affected customer data to identify which customers will be provided notifications in accordance with applicable legal requirements.” Follow me on Twitter: @securityaffairs and Facebook and Mastodon Pierluigi Paganini (SecurityAffairs – hacking, data breach)

Google announced new AI-powered defenses against scam messages and call-forwarding abuse on Android, currently rolling out to eligible devices. The new measures aim to address the increased sophistication of scams targeting mobile users, including fraudulent bank alerts and voice-cloning attacks. “Mobile scams have evolved far beyond basic robocalls and phishing texts, turning into sophisticated operations that use spoofed numbers, fake bank alerts, and AI voice cloning,” Google says. “With scams growing harder to spot, it’s nearly impossible for users to catch every red flag themselves,” added the tech giant. Google says its existing Phone and Messages scam detection flags more than 5 million suspected scam calls and texts monthly, but the new measures are expected to catch even more threats.

The Legal Aid Agency (LAA), an executive agency of the UK's Ministry of Justice that manages the country's Public Defender Service, says attackers who breached its IT systems in April 2025 stole records dating back to 1978. The agency employs around 1,250 staff, oversees billions in legal funding, and works with approximately 2,000 providers, including barristers, solicitor firms, and non-profit organizations that deliver civil and criminal legal aid services in England and Wales. The LAA disclosed the cyberattack in early May 2025, warning that payment information for legal aid providers might have been compromised. Two weeks later, it confirmed the resulting data breach was more serious than first believed after finding that attackers had stolen a large trove of sensitive applicant and recipient data from 2010 onward, including contact details, dates of birth, national ID numbers, criminal history, employment status, as well as contribution amounts, debts, and payments.
