Over the weekend the Securinets Quals CTF ran worldwide. As part of the technical team I contributed two challenges: a compact pyjail (sandbox escape / exploitation) and a structured forensics scenario.

In this writeup, you’ll find the detailed solution for my two chalenges:

• Easy Jail, a minimal Python sandbox designed to test creative use of restricted language features.
• Recovery, a realistic snapshot that exercises evidence discovery and timeline reconstruction skills, emphasising careful triage and reproducible analysis.
