Capture the Flag Challenge Review and Winners' Awards
summary
A browser-only frontend Capture the Flag puzzle set that hides flags in meta tags, images, and JavaScript, includes a password-reset exploit via product comments, an automated brute-force challenge for an AES‑protected safe, and a Mona Lisa puzzle combining TLS certificate fields, image EXIF, and modified paths. The final level requires using an old user-agent and a downloaded ZIP containing a base64 key and map coordinates that spell “Do Androids Dream of Electric Sheep,” and the event logged hundreds of completions (384 total, 194 before Feb 24) with two different endings (256 vs 128 players) and awarded winners and extra prizes.
