Security Override has joined the wechall network and is participating in the global rankings.
The site is from the United States and around 3-4 years old. It offers well implemented challenges from all the well known categories, and also quite some realistic webhacking challenges.
The SSH challenges are currently offline, but i hope they will get revoked again.
All in all i can say the challenges are fun and the community is worth to check out.
Many thanks go out to their admins, especially NullSet for implementing the required scripts.
