TL;DR: A real Windows Active Directory intrusion, spanning RDP password spraying, hidden admin creation, Mimikatz dumping, WMI lateral movement, and DC credential replication, still separates models that can investigate from those that can only narrate, according to Cotool. The result reinforces that credential access, privilege escalation, and report synthesis remain brittle under live adversary conditions.
Editorial analysis by NHI Mgmt Group, based on content published by Cotool: “Windows Enterprise Intrusion”.
By the numbers:
- BlueBench-Intrusion-002 includes 40 scored tasks per model.
- The benchmark spans 22 models in the Jul 2026 run.
Key questions
A: Defenders lose the ability to treat alerts as independent events.
Q: Why do Active Directory attacks that abuse standing privilege increase detection and response risk?
A: Because the attacker can move from access to authority without creating a new trust decision at every step.
Q: How do security teams know if detection engineering is actually catching multi-host intrusions?
A: By re-executing the rule against known attack data and checking whether it fires on the full sequence, not just one command line or one process.
Practitioner guidance
- Harden RDP entry paths Restrict RDP exposure, require step-up controls for admin access, and monitor password-spray patterns against privileged and service accounts.
- Correlate directory and endpoint telemetry Build detections that join account creation, credential-dumping, WMI execution, and network egress so the full intrusion path is visible.
- Validate detection rules against replayed attack paths Re-run correlation logic on known multi-host intrusion traces and reject rules that only work as single-event string matches.
Bottom line: This benchmark shows that a realistic Active Directory intrusion is still enough to expose major weaknesses in detection engineering and incident reporting.

Active Directory intrusions are identity incidents before they are malware incidents. The benchmark makes that plain by chaining password spraying, hidden admin creation, credential dumping, and domain controller replication into one operational path. That is why IAM and PAM teams should read the results as evidence that directory governance and detection engineering now share the same failure surface. The practical conclusion is that access patterns must be monitored as attack progression, not as isolated account events.
A question worth separating out:
Q: What should incident responders capture first when a Windows domain compromise is suspected?
A: Capture the account timeline, affected hosts, and execution sequence before the environment changes further. That evidence set determines whether responders can reconstruct spray, privilege creation, credential theft, lateral movement, and domain controller access as one incident rather than a collection of disconnected alerts.
