Live Stream VOD: GitHub Bug Used to Infect Game Hackers With Lua Malware
🕑 Added 2024-03-12 14:16:42 +0000 UTCIn this stream we analyze a unique delivery chain that uses a bug in GitHub to mimic popular repositories and deploy malware. We also do a deep dive into Lua malware!
The first 30min are describing the GitHub delivery of the malware, the Lua work starts after that. The real Lua work starts around 2h 55m when we build a custom Lua JIT interpreter with our own instrumentation hooks!
Special Thanks
