Automatic disruption of human-operated attacks through containment of compromised user accounts

Based on incidents analyzed by Microsoft, it can take only a single hop from the attacker’s initial access vector to compromise domain admin-level accounts. For instance, an attacker can target an over-privileged service account configured in an outdated and vulnerable internet-facing server. Highly privileged user accounts are arguably the most important assets for attackers.

In addition to compromising existing accounts, attackers have adopted the creation of additional dormant, highly privileged user accounts as persistence mechanisms.
