Anticipated Attack Path
- 1. Initial Access: Authorized attacker gains access to the system
- 2. Privilege Escalation: Attacker exploits vulnerability in PowerShell to elevate privileges
- 3. Persistence: Attacker maintains access and potentially moves laterally within the system
Am I Vulnerable?
- Verify PowerShell version and patch level
- Monitor system logs for suspicious activity
