Kerberoastable Service Accounts

Identify service accounts with SPNs vulnerable to Kerberoasting by extracting and cracking TGS tickets offline to compromise Active Directory credentials.

Kerberos Pre-Authentication Not Required

Identifies accounts with DONT_REQUIRE_PREAUTH set, enabling AS-REP roasting attacks to capture and offline-crack Kerberos hashes without credentials.

Kerberos vulnerability discovery identifies weaknesses in the domain's authentication configuration. Key targets include accounts with pre-authentication disabled (AS-REP roastable), service accounts with weak passwords vulnerable to Kerberoasting, hosts configured for unconstrained delegation, and SPNs set on high-privilege accounts.

The subpages walk through detection methods for each of these misconfigurations and how to assess their impact in the domain.
