PACTF_2017: Dinosaur Never-Forget System

Category: Points: 30 Description:

Those Dinosaurs… The dinosaurs need some way to archive their messages and news for the future, so they created the Dinosaur Never-forget System. They wanted the login to be public, but they also didn’t want it to be too easy to find. So they hid it in a system more antiquated than the dinosaurs themselves.


They kept records, too.


A simple challenge involving TXT DNS records.
