Key service for malware developers taken offline

The takedown of AVCheck, a major Counter Antivirus (CAV) service used by cybercriminals, disrupts their ability to test malware against antivirus detection, thereby hindering successful attacks. Matthijs Jaspers from the High Tech Crime Team highlighted that this operation is crucial in combating organized cybercrime, as it prevents early-stage criminal activities. The investigation revealed connections between AVCheck and other services like Cryptor.biz and Crypt.guru. Additionally, law enforcement has taken proactive measures, including deploying a fake login page to deter AVCheck users and collaborating with Project Melissa to target malware services. The need for coordinated efforts among various sectors is emphasized to effectively combat cybercrime.

Microsoft Copilot+ Recall: who should disable it, and how

Microsoft's Recall feature for Copilot+ PCs was initially announced a year ago but delayed due to privacy concerns raised by cybersecurity experts. The updated version was released in April 2025 for Windows Insider Preview builds and rolled out more broadly in May. Key updates include requiring user permission for activation, encrypting database files with hardware-based Trusted Platform Module (TPM), and implementing a filter to prevent saving sensitive information. Recall is enabled on a per-user basis, can be uninstalled, does not require a Microsoft account, and processes data locally. However, it still has vulnerabilities, such as allowing access with a regular Windows PIN after initial biometric authentication and failing to consistently filter sensitive data. Recall can log interactions during calls and capture self-destructing messages, posing privacy risks. It can impact performance and battery life, especially during gaming. Users handling sensitive data or frequently using video conferencing may want to disable or remove Recall. Instructions for disabling or removing Recall are provided, along with precautions for those who choose to use it.

Microsoft starts final Windows Recall testing before rollout

Microsoft is gradually introducing its AI-powered Windows Recall feature to Insiders in the Release Preview channel, with plans to extend it to all Windows users with Copilot+ PCs. Recall captures screenshots of active windows at regular intervals, allowing Windows 11 users to search for text within these snapshots using natural language. Users can opt-in to save snapshots and must authenticate via Windows Hello to access their data. Recall is currently being rolled out to Windows 11 Insiders with Build 26100.3902 (KB5055627). The feature faced privacy concerns upon its introduction in May 2024, leading Microsoft to implement measures to enhance user privacy, such as filtering out sensitive information and allowing users to adjust storage settings. The rollout of the first Recall preview began in November 2024 for Snapdragon Copilot+ PCs, followed by Intel and AMD Copilot+ PCs a month later.
