A credit card skimming group reportedly compromised a shared analytics script used by e-commerce platform Convertr to steal shoppers’ payment data during checkout. The campaign was identified on October 24 and has been attributed to a Brazilian gang, active since at least July 2024, that focuses on infecting online stores running Magento, OpenCart, and WooCommerce platforms. Convertr is a Brazilian e-commerce platform that powers online stores and checkout systems for dozens of major fashion brands in the country, handling R$2 billion ($370M) in sales. E-commerce security firm Sansec says that the attacker modified the Plausible tracker file hosted on a self-managed server operated by Convertr. Ecommerce cybersecurity company Sansec says that the attacker modified the tracker file on a self-hosted server for Plausible, an open source alternative to Google Analytics, managed by Convertr.
Microsoft has released out-of-band (OOB) Windows updates to remove trust in certificates tied to compromised eMudhra certificate authority keys, protecting systems that do not receive automatic certificate trust updates. The KB5134133 update for Windows 11 versions 24H2, 25H2, and 26H2 and the KB5134125 update for Windows 10 versions 21H2 and 22H2 were released on October 26. The updates are for systems without Internet access, devices that cannot access Microsoft's certificate-update service, and those where automatic Certificate Trust List (CTL) updates have been disabled. The updates were released after the discovery of eight eMudhra intermediate certificate authority private keys that were so weak they could be recovered almost instantly. All eight keys were generated in April 2025 and had values smaller than 256, allowing anyone to recover them by testing just 256 possible numbers.
Attackers are increasingly abusing legitimate IT tools, Microsoft 365 sessions, and everyday workflows to compromise businesses without triggering traditional defenses. Huntress Labs ranks the threats hitting organizations hardest, highlighting which attack techniques deserve immediate attention and which remain emerging risks.
Apple has backported security patches released last month to older iPhones and iPads, addressing a zero-day bug exploited in "extremely sophisticated" targeted attacks on iOS devices. Apple patched the same vulnerability in September for devices running iOS 26.7.1 and iPadOS 26.7.1, macOS Tahoe 26.7.1, and macOS Sequoia 15.8.1. Meta Product Security discovered this out-of-bounds write weakness (tracked as CVE-2026-86950) in CoreGraphics, a framework used for two-dimensional vector graphics, text drawing, and image rendering across iOS, macOS, iPadOS, watchOS, and tvOS. Successful exploitation of out-of-bounds write security issues can let attackers crash programs, corrupt data, or gain remote code execution by writing data outside the allocated memory buffer. "Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals on versions of iOS before iOS 27," Apple warned on Monday.
A criminal using the Amadey malware can no longer access or steal data from 180,000 infected computers around the world, including some in Australia, the Australian Signals Directorate (ASD) says. The agency's operators gained access to the criminal's operation's backend and cut it off from those computers. "The next steps that we took were to disconnect that Amadey controller from all those
French energy giant ENGIE, one of the world's largest power and natural gas providers, confirmed that attackers stole customer data after breaching a marketing platform used by business partners. ENGIE operates in renewable energy, infrastructure, and customer energy supply in 30 countries, employs over 90,000 people, and reported €71.9 billion in revenue last year. An ENGIE spokesperson told BleepingComputer that it cut off the attackers' access to the compromised platform and that they didn't breach the company's internal systems. "ENGIE's internal IT systems were not compromised. ENGIE recently identified unusual data access activity within a tool used by partners as part of their customer prospecting activities and the marketing of energy offers," the spokesperson said. The ENGIE spokesperson didn't say how many customers were affected, but told BleepingComputer the incident is limited to customers in France.
OpenAI's compaction feature, which shrinks a long conversation to save space, could be turned into a way to copy a model's hidden reasoning out in plain text, security firm Xint has shown. OpenAI's reasoning models work through a problem before answering, and the service normally returns only the raw reasoning as an encrypted item the user cannot read. The method got past
The Computer Emergency Response Team of Ukraine (CERT-UA) has issued an alert warning of unauthorized remote access to video surveillance systems manufactured by Dahua. "Cases of compromising IP cameras and DVRs with access to the video stream, changing the device configuration and creating third-party accounts have been recorded," the State Special Communications Service of Ukraine (SSSCIP)
The University of Copenhagen in Denmark confirmed that hackers accessed one of its test environments containing personal data belonging to 525,000 people. The educational organization detected the breach last Tuesday and disclosed it on Friday. In an update yesterday, the university added another 20,000 staff and students whose PIN codes were exposed. “The University of Copenhagen has confirmed a cyber attack in which hackers gained access to one of the university’s test environments,” the university says. Founded in 1479, the University of Copenhagen is Denmark’s oldest university and one of its leading research institutions. It has approximately 36,800 students and 10,700 employees, with six faculties and more than 200 research centers. The University of Copenhagen is still investigating to determine the extent of the incident, but warns that the following information may have been exposed:
OpenAI has launched GPT-6.1 Terra, a new model focused on computer use, visual reasoning, coding, and everyday work, while costing significantly less than its larger models. Terra is designed as a faster and cheaper option for tasks such as filling out forms, editing videos, interpreting technical drawings, and automating repetitive desktop work. "We’re introducing GPT-6.1 Terra, a fast, efficient model that combines detailed visual reasoning and precise computer use alongside clearer, more natural writing," OpenAI explained in a blog post. "A significant step up from GPT-5.6 Terra, it excels at the communication and computer-based tasks that fill the workday, from drafting proposals and interpreting technical drawings to filling out forms and editing videos." OpenAI says GPT-6.1 Terra's API pricing is 50% lower than GPT-5.6 Terra and GPT-6.1 Sol, at $1 per million input tokens and $5 per million output tokens.
