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)

Bonus content:

• t2’09 challenge solutions (via the Reverse Engineering Reddit)
• Hacking Challenges: Have Fun Improving Your Skills! [PDF] – presentation from the RaDaJo guys

Have fun!
