Live Stream VOD: AMSI Bypass Loader Part 2
Added 2023-06-20 15:01:02 +0000 UTCIn this Twitch stream we continue our triage of this new loader that uses AMSI bypasses to avoid detection. In this part we focus on the injected X64 shell code. The shell code uses relative offsets to access data within itself which poses some challenges for IDA, and it contains multiple encrypted strings as well as another PE file.
