Live Stream VOD: Guloader NSIS Delivery Analysis
Added 2022-12-20 05:23:04 +0000 UTCIn this twitch stream we take a second look at Guloader with a focus on its highly obfuscated delivery chain. An NSIS loader is used to execute multiple layers of obfuscated PowerShell which eventually lead to the Guloader shell code.
The goal of this stream is to better understand the obfuscated NSIS delivery techniques used by Guloader and compare them to other iterations of their delivery chain with an aim to identify commonalities.
This stream ends up being just Part 1 as we don't get the final shell code fully extracted... stay tuned for Part 2!

We have a few more streams to do on guloader in the new year! We can def add this and see how much has changed between the sample we are analyzing now and this one!
