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

📜 Abusing Code Signing Certificates

Abusing code signing certificates is not new. In the past few years alone, it has proven to be an effective method of bypassing certain security controls to allow malicious software to run and look seemingly benign. This article describes code signing methods, as well as tools for copying the signature from legitimate PE files.

A DLL loader with advanced evasive.

Features:
• DLL unhooking from \KnwonDlls\ directory, with no RWX sections
• The encrypted payload is saved in the resource section and retrieved via custom code
• AES256-CBC Payload encryption using custom no table/data-dependent branches using ctaes; this is one of the best custom AES implementations I've encountered
• Indirect syscalls, utilizing HellHall with ROP gadgets
• Payload injection using APC calls - alertable thread
• Api hashing using two different implementations of the CRC32 string hashing algorithm
• The total Size is 17kb
