We've updated the security module used by "secure" Counter-Strike servers. Your server should update itself in the next while, so you don't need to do anything. This version of the security module detects versions of OGC and clients abusing the scr_ofs* cvars

Oh and a cute "YOU ARE CHEATER" message here. Given the infrastructure that's now in place as demonstrated by the auto-update of all the secure servers you can probably expect a few more things like this. To tell if a server is "secure" or not, there will not be a yellow icon next to the server in the in-game server menu. All CS servers are secure by default. Anyone notice a few less hackers out there?
