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 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.
