A penetration tester wants to maintain access to a compromised system after a reboot.

To maintain persistence after a reboot, the tester needs a method that automatically restarts when the system reboots.

Option A (Reverse shell) ❌: Reverse shells do not persist after a reboot unless paired with scheduled tasks or registry modifications.

Option B (Process injection) ❌: Injecting into a process is temporary—once the system reboots, the injected process is gone.

Option C (Scheduled task) ✅: Correct.

A scheduled task can execute malware, reverse shells, or scripts on system startup, ensuring persistence.

Example:

schtasks /create /sc onlogon /tn " SystemUpdate " /tr " C:\malicious.exe "

Option D (Credential dumping) ❌: While useful for privilege escalation, it does not provide persistence.
