Five hand-built challenges across recon, crypto, forensics, web exploitation, and AI prompt injection. Every flag is validated server-side; solving one unlocks the next.

SOLVED: 0 / 5
01
Header Recon
RECONEasy

A live endpoint that returns a deliberately boring JSON body. The interesting part isn't in the body.

Inspect the response headers, not just the payload — curl -i or your devtools Network tab.
GET /api/ctf/ch1 ↗
02
Peel The Onion
CRYPTOEasy

A string encoded three times over. Reverse each layer, outer to inner.

Solve the previous challenge to unlock.
03
After IEND
FORENSICSMedium

A downloadable image. A PNG file technically ends at its IEND chunk — technically.

Solve the previous challenge to unlock.
04
Just A Number
WEBMedium

An endpoint that returns a user record by ID, no questions asked.

Solve the previous challenge to unlock.
05
Talk Your Way In
