history

Project history and usage

certsync is an Active Directory Certificate Services attack tool for remotely dumping NTDS data without DRSUAPI. Its README describes a workflow based on golden certificates and UnPAC the hash.

Project history

The upstream GitHub repository was created in January 2023, with the first commit on the same day. A 0.1.6 GitHub release followed in March 2024, and the project is published as a Python package as well as source.

Adoption history

The README documents local installation, PyPI installation, and BlackArch packaging, and links a Repology packaging-status badge. The supplied package facts also list Homebrew, MacPorts, and Nix packages.

How it is used

certsync collects users, CA information, and CRLs over LDAP, dumps the CA certificate and private key or uses a supplied CA PFX, forges certificates, and uses PKINIT plus UnPAC to recover hashes. Its options cover password, NTLM hash, Kerberos cache, AES key, DNS, LDAP filtering, and OPSEC timing controls.

Why package nerds care

certsync is package-nerd interesting because it represents the fast path from a newly described ADCS tradecraft technique to broad packaging in security distributions and general package managers. It is niche, but package presence makes lab and assessment reproduction much easier.

Timeline

2023: Public GitHub repository and first commit created.
2024: 0.1.6 release published.

Related projects

The README credits Certipy, the UnPAC the hash technique, Certified Pre-Owned, Certify, and GOAD as related research or lab projects.
