Description

Currently, the Mimikatz module embeds a custom version of SharpSploit to load and execute the Mimikatz DLLs in memory (it's just calling Assembly.Load() on it). From an Opsec perspective this sucks cause it's a static assembly, doesn't get dynamically compiled on the endpoint and it's just another thing AMSI can trigger on in .NET 4.8.

Ideally I would LOVE to port over the SharpSploit PE Loading code to Boolang so this entire issue goes away but it's def not trivial and is going to require a decent amount of time.

Contributor guide

Research direction
Examine SharpSploit's PE loading code to understand how it loads and executes PE files in memory using System.Reflection.Emit.DynamicMethod. Then port that logic to Boo language, ensuring the code dynamically compiles on the endpoint instead of using a static assembly. Focus on maintaining Opsec improvements.
