Mimikatz is required for the Monkey to be able to steal credentials on Windows. It's possible to either compile from sources (requires Visual Studio 2013 and up) or download the binaries from
|

https://github.com/guardicore/mimikatz/releases/tag/1.0.0

Download both 32 and 64 bit zipped DLLs and place them under [code location]\infection_monkey\bin
|
||||
Alternatively, if you build Mimikatz, put each version in a zip file.
|
||||
1. The zip should contain only the Mimikatz DLL named tmpzipfile123456.dll
|
||||
2. It should be protected using the password 'VTQpsJPXgZuXhX6x3V84G'.
|
||||
3. The zip file should be named mk32.zip/mk64.zip accordingly.
|
||||
4. Zipping with 7zip has been tested. Other zipping software may not work.
