Candiru spyware was delivered to devices at Al Jazeera Media Network via targeted online advertisements in a zero-click attack that required only rendering the malicious ads on the victim's device. Researchers at Citizen Labs investigating the attacks referred to this technique as AdFection, noting that their report is the first public technical confirmation of mercenary spyware delivered through targeted ads. A similar method was documented in late 2025 by Amnesty International, involving ads that infected targets with Predator spyware without them clicking anything. That infection mechanism was called Aladdin and surfaced due to a collection of marketing files and documents leaked from the Intellexa surveillance company that researchers studied and corroborated with technical details from forensic investigations.
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.

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)
BeyondTrust warned customers on Thursday to patch a critical flaw in its Remote Support (RS) that has been exploited in zero-day attacks since late August. Remote Support is the company's enterprise-grade support solution that helps IT service desks, help desks, and customer support teams troubleshoot issues remotely. Tracked as CVE-2026-102764, this actively exploited authentication bypass vulnerability lets unprivileged remote attackers perform file operations on unpatched appliances and affects RS 26.2.3 or earlier. BeyondTrust patched the security issue for all Remote Support and Privileged Remote Access SaaS customers on October 8, but self-hosted installations must be patched manually if automatic updates are not enabled. While the company shared limited details about the vulnerability, it said the zero-day was abused in the wild by a suspected China-nexus espionage actor tracked by Mandiant and Google Threat Intelligence Group (GTIG) security researchers as "Armory Castle" (formerly UNC5221) and by cybersecurity firm CrowdStrike as "Warp Panda."
The China-nexus cyber espionage group tracked as Armory Castle (previously UNC5221 or Warp Panda) exploited a newly disclosed security flaw in BeyondTrust Remote Support (formerly Bomgar) as a zero-day in late August 2026. The vulnerability, tracked as CVE-2026-102764 (CVSS score: 9.3), is a case of improper origin validation in an internal messaging component that could be exploited by a
