Assumed Breach and Privilege Escalation Case

Weak authentication and poor segmentation enabled privilege escalation from VPN access to full domain control.

The challenge

The assumed breach scenario tested infrastructure security by simulating insider threats. Major weaknesses included 2FA absence, weak endpoint security, and poor segmentation.

The solution

  • Enforced 2FA on VPN and O365 to block unauthorized access.
  • Improved AD security by restricting certificate services.
  • Strengthened endpoint hardening using CIS benchmarks.

How we did it

  • Exploited open VPN access and AnyDesk admin controls.
  • Used DCSync & Shadow Credentials for privilege escalation.
  • Performed lateral movement through SMB pivots.

Conclusion

The engagement exposed weak security configurations, allowing undetected privilege escalation. Network segmentation and MFA were prioritized for mitigation.
