Problem Statement
How do you safely prove a blind vulnerability like blind command injection or blind SQL injection?
Explanation
Use out-of-band or timing-based signals that do not touch sensitive data. For timing, use a tiny, bounded delay and run it once. For out-of-band, use a controlled collaborator endpoint to receive a single DNS ping. Keep the probe minimal, log the exact time, and stop after you observe the signal.
Share the smallest proof that demonstrates control, then focus on fixes. Avoid extra trials in production.

Timing probe: add a two-second delay once and measure response time O O B probe: resolve unique token.your-listener.example once
