Monitoring lateral movement paths in AD

Monitoring Lateral Movement Paths in Active Directory Lateral movement is what happens after an attacker (or rogue insider) gets an initial foothold: they pivot from one machine/account to another until they reach high-value targets like file servers, application tiers, and ultimately Domain Admin or Tier-0 assets. In Active Directory (AD), lateral movement succeeds not…

Using canary tokens in AD to detect breaches

Canary tokens are deliberate “tripwires”: objects, credentials, or breadcrumbs that should never be touched in normal operations. When an attacker (or an automated tool) interacts with them, you get a high-signal alert that something is wrong—often early, before full domain compromise. This guide focuses on practical canary patterns that work well in Active Directory…

How to deploy deception techniques in AD

Deploying Deception Techniques in Active Directory (AD): A Practical Defender’s Playbook Deception in Active Directory is about placing high-signal, low-risk traps where real attackers naturally go—so you detect early, confirm intent faster, and reduce time-to-contain. Done well, deception doesn’t replace monitoring; it amplifies it by turning attacker curiosity into reliable alerts.

Analyzing LSASS memory dumps for credential theft

LSASS (Local Security Authority Subsystem Service) is the Windows process that handles interactive logons and manages authentication-related secrets in memory. Because it sits at the center of Windows authentication, attackers often try to access or dump LSASS memory to steal credentials or reusable secrets. This guide focuses on defensive detection, triage, and response—what to look…

Detecting Shadow Admin accounts

1) What is a “shadow admin” in AD? A shadow admin is any user, group, or service principal that can achieve admin outcomes—such as modifying privileged group membership, controlling GPOs, resetting admin credentials, or replicating directory secrets—without being a direct member of obvious privileged groups. Why they’re hard to spot They hide in structure…
