Kerberoasting is the single most common Active Directory attack encountered on pen-test engagements. It’s low-noise, low-skill, highly reliable, and when it succeeds, the attacker holds privileged service account credentials — often Domain Admin. Understanding it is essential for both the offence and defence sides.
Kerberoasting is the single most common Active Directory attack encountered on pen-test engagements. It’s low-noise, low-skill, highly reliable, and when it succeeds, the attacker holds privileged service account credentials — often Domain Admin. Understanding it is essential for both the offence and defence sides.
This is a hands-on module. You will see the exact attacker commands, exactly what happens on the wire, the defender’s detection opportunities, and the concrete remediations.
Prerequisites
- Module 1 of this path (AD Architecture Fundamentals)
- Any domain-user foothold — a cracked password from phishing, a default credential, or a vulnerability that gives you a user-level session
- Network access to a Domain Controller on port 88 (Kerberos)
- A cracking rig (CPU is fine for moderate-complexity passwords; GPU is faster)
