Kerberoasting exploits the Kerberos authentication protocol in Windows Active Directory environments. Current detection relies on fragile heuristics, often producing false positives and missing nuanced attack patterns. The BeyondTrust research team is addressing the challenge of detecting anomalies in Kerberos traffic through a new statistical framework that enhances accuracy and minimizes false alerts. Key steps in the Kerberos process include requesting a Ticket Granting Ticket and service tickets, which attackers exploit by leveraging the encryption tied to service account password hashes. This necessitates improved defenses against such vulnerabilities.
Kerberoasting continues to evade typical defense methods due to detection reliance on brittle heuristics and static rules, generating false positives and missing subtle attack patterns.
Existing detection mechanisms for Kerberoasting fail to accurately identify low-and-slow attacks, necessitating a more precise approach to anomaly detection in Kerberos traffic.
The BeyondTrust research team has developed a statistical framework aimed at improving Kerberos anomaly detection accuracy while significantly reducing false positives in security alerts.
Kerberos authentication involves several steps, with TGS requests recorded as Windows Event 4769, a critical point where attackers may exploit service tickets for unauthorized access.
