[Share][CS:S]Kigen's Anti-Cheat

[Sinaya]

This is the KAC Open Beta of version 1.2. This version is a complete rework of KAC from the ground up with the exception of the networking part, which is to be reworked later when the KAC Network is rewritten from the ground up itself.

 

Basic Change Log:

 

  1. Everything was rewritten from the ground up except the network code.

Commands and ConVars

 

KAC 1.2 has a completely different system for settings than the previous versions.

---

Here is the list of commands.

 

  1. kac_addcvar <cvar name> <comparison type> <action> <value> <value2 if bound>

  2. kac_removecvar <cvar name>

  3. kac_addcmd <command name> <ban (1 or 0)>

  4. kac_removecmd <command name>

  5. kac_status

---

 

Here is the list of convar settings.

 

  1. kac_version - Version of KAC (not changable)

  2. kac_client_enable - Enable Client Module.

  3. kac_client_balance - Force everyone to auto-assign when joining a team.

  4. kac_client_antirejoin - CS:S only. Prevents the rejoin exploit which allows a person to play twice in one round.

  5. kac_client_nameprotect - Prevent name exploits.

  6. kac_client_antispamconnect - Seconds a person needs to wait between connection attempts or they'll get IP banned for a minute. (0 = disable)

  7. kac_cmds_enable - Enable Command module.

  8. kac_cmds_spam - Amount of commands in one second a person may enter before getting booted for command spam. (0 = disable)

  9. kac_cmds_log - Logs all command usage into separate files based on server instance. Useful for debugging if you think someone is crashing your server by a command.

  10. kac_cvars_enable - If the CVar detection engine is enabled or not.

  11. kac_eyes_enable - If the Eye Test detection routine is enabled or not. (Disabled on INS and CS:S.)

  12. kac_eyes_antiwall - Enable KAC's Anti-Wallhack routine. This renders wallhacking ineffective.

  13. kac_rcon_crashprevent - Prevent a specific crash with RCON. Default is disabled because it will expose your server to brute force guess attempts. Make a strong password before enabling this.

About the Command Engine

 

This part of the plugin was designed to monitor command usage by players on the server in order to prevent abuse of commands. By default this engine will prevent players from using certain exploitable commands that can cause the server to crash. It will also monitor how many commands the player is entering in one second.

About the CVar engine

 

I have rewritten this part of the plugin from the ground up to be dynamically allocated so that you can freely add and remove ConVars to and from the list. Lets say you don't like the built-in list preventing people from joining your server with server side plugins on their client. You can now remove them as you see fit. Lets also say that you may not want people messing with their net_graph while connected to your server. All you'd have to do is enter the command " kac_addcvar net_graph equal kick 0 " and your done.

About the Eye Test engine

 

This one is the new detection routine. You aren't likely to see a whole lot from it but what it does is test for impossible eye angles coming from clients. By default a client will never send eye angles past 90 and -90 degrees on the X or Z axis. Cheats however disable this behavior for a multitude of cheat features. This part of the plugin now enables KAC to test for these.

---

About the Network engine

 

This has basically been the only thing left over from previous versions of KAC. It has been optimized and now also includes a Auto-Update feature so that it can download the latest KAC directly from the KigenAC website. I have plans to rewrite the entire KAC Network (aka the KAC Master server) from the ground up to be more flexible and more feature oriented so that you can use the KAC Network to do more than ever (feature details are private at this time).

---

About the RCON engine

 

This is about the only thing that needs true testing. I've made this part in an attempt to more accurately block the RCON crash via preventing the engine from handling it by itself. This feature does not interfere with the RCON bad password banning that the Source engine employs but makes it better by banning any players matching that IP out of the server before banning the IP.

---

About the Translation engine

 

This is my solution to the translation problem. It currently, during the Beta, will only have the English language, but when KAC 1.2 is official released it will contains many languages. The main reason why I created my own solution instead of using SourceMod's is mainly due to two reasons. I wanted to keep KAC compressed into one file and I've ran into issues in the past where SourceMod cached the first version of any particular text file to be loaded and wouldn't reload it basically preventing the updating of translations which is important now that KAC has a Auto-Update feature.
