Latest note from GameServers.com is that a security patch was applied to all Black Ops servers last night. There isn’t any other information on what the identified security issues are at this point but I will update with any information that I find. Could this be addressing the servers that have enabled power leveling through the console or are there other security issues that we should be aware of?

An emergency security patch is being applied to all Black Ops servers to fix an exploit that has been discovered. Your server will automatically restart once to apply the patch.

My call was spot on and based on a reply from [GS] devicenull on the GameServers.com forums this security patch addresses the power leveling servers.

The security issues were related to the power leveling, or fastrank, servers. This is all that was fixed in last nights patch.
