Mini CTF: put it together

Multi-step challenges that chain web, forensics, crypto, networks and OSINT, then a write-up.

Real CTF challenges rarely use one technique. A web page hides an encoded comment; a photo's metadata holds ciphertext whose key is somewhere else; a DNS record carries hex that needs a key from a second record. The method never changes: identify what you are looking at, transform one layer, look again, and keep notes. Finish like a professional, with a clear write-up: summary, steps, impact and fix.

A first example

Identify -> transform one layer -> look again -> repeat -> submit -> write it up.
