# Performing Exploit Verification

## When to Use

- After discovering a potential vulnerability during any scanning or testing phase
- Before calling `report_vulnerability` to prevent false positive reports
- When automated scanners (nuclei, nikto, etc.) flag an issue that needs manual confirmation
- When the initial exploit attempt is ambiguous (e.g., 500 error vs. actual RCE)
- As the final gate before reporting ANY finding to the client

## Most Often Missed & How to Confirm

- **Running the control test, not just the exploit** — the most common false positive is reporting a difference (size, status, timing) without a baseline + control proving the payload caused it. Always capture baseline → exploit → control.
- **Proportional timing for blind/time-based findings** — a single 5s delay can be network jitter. Confirm with SLEEP(0)/SLEEP(3)/SLEEP(7) and show the delay scales with the value, repeated 2-3x.
