After missing the announcement for the second part of the Network Forensics Puzzle (yes, I’m subscribed the feed now!) I would like to regain your trust by bringing two other contests to your attention:
- Miracle on Thirty-Hack Street from ethicalhacker.net
- the sevenfour challenges (a “keygen-me” type of challenge)
- t2’09 challenge solutions (via the Reverse Engineering Reddit)
- Hacking Challenges: Have Fun Improving Your Skills! [PDF] – presentation from the RaDaJo guys
