Apparently Assured Information Security (AIS) is looking for hackers. Not sure they can find any good ones here if I have to go by the number of solvers of The BrownOS, but hey, who knows?

In any case, they made a challenge site: Can You Hack It?®

Currently there is no support for linking to WeChall, but you do get an account id to keep track of your progress yourself.

Happy Challenging!
