Kigen's Anti-Cheat

IMPORTANT: KAC will NOT work with non-Steam (cracked) servers!
Cafe list system has been discontinued.

Goto http://kigenac.com/viewtopic.php?f=4&t=231 for the latest version.

This plugin was developed before both ES Anti-Cheat and VBAC. It was originally kept private in order to help prevent the bypassing of it, but since it was using similar methods that were published in ES Anti-Cheat and VBAC I fear it is only a matter of time before a bypass is made. So I decided to go ahead and give the community something useful before that time arrives.

KAC is a more advanced cheat CVar detector than ES Anti-Cheat or VBAC and was designed to detect most cheats. It will query and check for most cheat prone CVars and replicated CVars. Most cheats today currently disable CVar replication and also turn off sv_consistency and turn on sv_cheats and thus this plugin will detect those cheats. This plugin will enforce sv_cheats 0 on most servers. (Exception being RPG, I highly advise not turning sv_cheats on yourself.)

This plugin will also attempt to use SourceBans over local-bans if SourceBans is present.

It will also block the "unconnected" people.

Requirements
SourceMod v1.1.0 or higher.
Sockets v2.3.1 - Use the latest version available if possible.

Optional
IRC Relay - You must have it in order to use the IRC announcement option.

Server ConVars

• kac_version - Version of KAC. (No edit)
• kac_block_multibyte_names - Blocks people from using multibyte characters in their name. (Unicode)
  
• kac_block_namecopy - Block people from copying another's name. ( 1 (on) or 0 (off) )
• kac_irc_channel - Optional IRC channel to announce KAC actions. Requires IRC Relay for use. (String)

• 1.0.0 - Intial Release.
• 1.0.1 - Removed useless dependencies on cstrike and sdktools.
• 1.0.2 - Fixed round_freeze_end for servers that don't have it.

• 1.1.8 - Added Spam Checking. More optimizations to the code. Added define to exclude Sockets at will.
• 1.1.9 - Added fixes for a lot of crash exploits. Added checks for mat_dxlevel and third party server plugins running on clients. Added corruption checks. Fixed issues with admins messing with protected cvars.

Donating
I will proudly accept donation for the creation of KAC.
Please click here to donate. I'm jobless so some money for food would be appreciated.



Note: Due to the usage of the include socket.inc the plugin will no longer compile on the forums. I have provided a complied version.

I can confirm that this was built and been in testing before the previous anti-cheats were made. Good work Kigen.

It was too late once ES Anti-Cheat and VBAC were released. So the community might as well have something good to use for the time being.

The convars variables ar only 1 for ON an 0 for OFF?

If i don't have source bans the it stores the bans in the banned_user.cfg?
Does it stores somewhere some log if someone is caught?
