certsync

certsync is a new technique in order to dump NTDS remotely, but this time without DRSUAPI: it uses golden certificate and UnPAC the hash. It works in several steps:
1) Dump user list, CA informations and CRL from LDAP
2) Dump CA certificate and private key
3) Forge offline a certificate for every user
4) UnPAC the hash for every user in order to get nt and lm hashes

⭐️ Privileger

Privilger allows you to work with privileges in Windows as easily as possible. There are three modes:

— Add privileges to an account;
— Start a process by adding a specific privilege to its token;
— Remove privilege from the user.

🔑 Pass-the-Challenge

This blog post introduces new techniques for recovering the NTLM hash from an encrypted credential protected by Windows Defender Credential Guard. While previous techniques for bypassing Credential Guard focus on attackers targeting new victims who log into a compromised server, these new techniques can also be applied to victims logged on before the server was compromised.

💥 Shellcode Mutator

New tool to help red teamers avoid detection. Shellcode is a small piece of code that is typically used as the payload in an exploit, and can often be detected by its “signature”, or unique pattern. Shellcode Mutator mutates exploit source code without affecting its functionality, changing its signature and making it harder to reliably detect as malicious.
