VoidStealer malware steals Chrome master key via debugger trick
An information stealer called VoidStealer uses a new approach to bypass Chrome’s Application-Bound Encryption (ABE) and extract the master key for decrypting sensitive data stored in the browser. The novel method is stealthier and relies on hardware breakpoints to extract the v20_master_key, used for both encryption and decryption, directly from the browser’s memory, without requiring […]
Microsoft rolls out hardware-accelerated BitLocker in Windows 11
Microsoft is rolling out hardware-accelerated BitLocker in Windows 11 to address growing performance and security concerns by leveraging the capabilities of system-on-a-chip and CPU. BitLocker is the native full-disk encryption feature in Windows that protects data from being readable without proper authentication. During normal device boot, it relies on the Trusted Platform Module (TPM) to securely […]
RansomHouse upgrades encryption with multi-layered data processing
The RansomHouse ransomware-as-a-service (RaaS) has recently upgraded its encryptor, switching from a relatively simple single-phase linear technique to a more complex, multi-layered method. In practice, the upgrades offer stronger encryption results, faster speeds, and better reliability on modern target environments, giving threat actors stronger leverage during post-encryption negotiations. RansomHouse launched in December 2021 as a data extortion […]
GPU-powered Akira ransomware decryptor released on GitHub
Security researcher Yohanes Nugroho has released a decryptor for the Linux variant of Akira ransomware, which utilizes GPU power to retrieve the decryption key and unlock files for free. Nugroho developed the decryptor after being asked for help from a friend, deeming the encrypted system solvable within a week, based on how Akira generates encryption […]
