Hacking challenges

The following sites offer various short challenges (mostly hacking challenges) categorized as:

Your task is to review all the sites (provide feedback to your instructors!), then register on WeChall, which is sort of a score-tracking hub across all such challenge sites.

Then, you can register on any other of those sites and do their challenges. (You can also work on WeChall challenges first.) Most sites will require a registration before you can view the challenges, but let that not deter you from reviewing all the sites carefully. Some challenges will likely be over your head (and even your all-knowing instructors couldn’t solve them), some you should find fairly easy to moderate.

It depends on how good a hacker you want to become. ;)
