Me and the homies are dropping browser exploits on the red team engagement 😎. Find out how to bypass WDAC + execute native shellcode using this one weird trick -- exploiting the V8 engine of a vulnerable trusted application. ibm.com/think/x-force/…

I've been reverse engineering the xz backdoor this weekend and have documented the payload format and written a proof-of-concept exploit for the RCE. The payloads are signed with an ED448 key, so I patched my own key into the backdoor for testing. :-) github.com/amlweems/xzbot
Rough copy of the FORCEDENTRY code is now available. Most relevant code is here: github.com/jeffssh/CVE-20… Blog soon!
