# Performing Web Cache Deception Attack
## When to Use
- When testing applications behind CDNs or reverse proxies (Cloudflare, Akamai, Varnish, Nginx)
- During assessment of authenticated page caching behavior
- When evaluating path normalization differences between caching and origin layers
- During bug bounty hunting on applications with aggressive caching policies
- When testing for sensitive data exposure through cache layer misconfiguration
### How to CONFIRM a Hit (avoid false negatives)
- **Positive signal**: an authenticated response gets stored under a static-looking path and is then **readable by a completely anonymous client** — confirm with the second, unauthenticated request returning the victim's data and `X-Cache: HIT` / `CF-Cache-Status: HIT` / `Age > 0`.
- The whole vulnerability lives in the **second read**: a single authenticated request that returns profile data proves nothing on its own.
- Do NOT conclude "not vulnerable" until you have:
