Upside-Down-Ternet is a funny example of what one guy did to his leeching neighbours.

If you still are under the illusion that WEP is a safe way to secure your wireless access point, think again. Read how the FBI demonstrated cracking WEP in 3 minutes.

Every kid goes through a stage where secret codes and invisible ink are exciting. Eventually though, you find that what you need to say to your buddies is not really top secret and the effort to encode your "Let's go play hockey" message is impractical.

I still find cryptography interesting and the article How I Broke The Confederate Code (137 Years Too Late) is very cool.

When a computer is compromised one of the first things the intruder does is install a root-kit. The article How to scan your Linux-Distro for Root Kits is an excellent step-by-step HOWTO to detect if your systems have been kitted.
