Ethical Hacker challenge “Prison Break” solution
As I usually do, I’ll publish my entry for the Ethical Hacker challenge after the deadline passed: Challenge Question 1: What is the most probable reason Michael could not get network connectivity from the desk Ethernet jack?

T2’09 Challenge
Sorry for being a little late: the T2’09 challenge just started. Via the F-Secure weblog. Don’t be fooled by the fact that page already contains two entries (“Mr. Speed” and “Mr. Style”) in the top.

Careful with that axe^H^H^H static, Eugene!
