Understand and detect lateral movement

Why it matters

Almost no serious intrusion stays on the first machine. An attacker lands somewhere ordinary -- a phished laptop, an exposed service -- and the damage comes from what happens next: they walk sideways, host by host, hunting for the file server, the domain controller, the data. That sideways walk is lateral movement, and it is where a fast defender can still win, because the attacker has to keep authenticating and keep creating footholds, and each of those leaves a record. The catch that most tutorials skip is that those records look almost exactly like a busy administrator's normal Tuesday:…

What you'll learn

Steps in this lab

  1. What lateral movement and east-west traffic are
  2. How they move, part 1: remote services and admin shares
  3. How they move, part 2: pass-the-hash and remote footholds
  4. Signal 1: unusual internal logons (Event ID 4624 and logon types)
  5. Signal 2: remote footholds and admin-share writes
  6. Baseline normal FIRST, then hunt
  7. Two detection queries to keep
  8. The honest catch: a signal is a lead, not a verdict
