I invariably seem to hear about the hacker challenge stories on the EthicalHacker site only after the deadlines have passed. I’m not sure if I’m the one who is behind or if it has anything to do with the headache-inducing site they have which looks like a freakish juxtaposition of a forum with news script software from 1998 (yet powered by Joomla!). Great books! Messy site!
At any rate, their latest challenge is up and hopefully the chosen answer sometime soon!
