VoidStealer Bypasses Chrome ABE With Debugger Trick
- VoidStealer evolved to extract Chrome's V8 master key via debugger attachments, bypassing application-bound encryption without code injection or privilege escalation.
- It sets hardware breakpoints on hidden browser instances, intercepts keys, and decrypts cookies offline, lowering detection risk.
Detect Debugger-Based Browser Key Theft
- Detect debugger attachments to browser processes and unusual memory reads to spot VoidStealer-style attacks.
- Monitor for hidden browser launches from untrusted parent processes, which remain uncommon in legitimate environments.
