A post on CS-Nation (thanks Shacknews)
reproduces an email sent to the Half-Life dedicated servers mailing list by
Valve's Eric Smith describing how the Half-Life master server is going to start
compiling lists of cheaters. Here's the word:
Security module update
*** This only affects Counter-Strike servers. ***
We've updated the public security modules again. Your Counter-Strike servers
should update themselves automatically. If you find your servers are suddenly
having problems, try restarting the servers.
These modules should detect OGC's OpenGl Hack 1.8 and will start reporting
detected cheaters to our master ban list server. We won't be banning anyone yet,
but we'll be gathering information about detected cheaters. You will see
outgoing traffic to: 188.8.131.52:27013.
