VoidStealer malware steals Chrome master key via debugger trick VoidStealer, an infostealer seen in the wild, bypasses Chrome’s Application-Bound Encryption (ABE) by using hardware breakpoints to extract the v20_master_key directly from browser memory. The malware attaches as a debugger to suspended browser processes at startup, reads the register holding the plaintext master key, and uses ReadProcessMemory to steal it, a technique likely adopted from the open-source ElevationKatz project. #VoidStealer #v20_master_key
