| Author: Noah | |
| @subTee's reflexive loader | |
| Required Dependencies: msbuild, csc | |
| Execute: Run-UpdateKatz -Verbose | |
| This will download the latest mimikatz source and @subTee's reflexive PE loader, unzip, compile, | |
| encrypt, and package the mimikatz binary into Procmon64.exe. The file itself will bypass AV. | |
| Running is a different story. | |
| Obviously run this from a clean machine, disable AV so you don't lose mimikatz | |
