Interview question · Systems, OS & Memory Safety

What are the common classes of Windows local privilege escalation, and how do you harden an estate against them?

Kernel exploits make headlines; misconfigured services, impersonation and stored credentials do the work. The scored answer groups escalation into classes and attaches a control and a detection to each.

What if · the follow-ups in this answer

The answer works through 6 follow-ups like an interviewer would

A pentest gets a low-privileged shell on a Windows server and reports several paths to SYSTEM.

  1. Which configuration classes cause most local escalation?
  2. Why are service account token privileges risky?
  3. What about stored credentials?
  4. How would you fix the findings?
  5. How do you prevent recurrence?
  6. How would you remediate the server and fleet?

Each rung has a nudge, a model answer, the principle that carries over and the weak answer to avoid. Premium opens every answer and ladder.
