EVO Anti-Cheat 1.3

About:

This is a new server-side anti-cheat developed for OpenMP, whose goal is to have security and absolute control over the player's data (info).

It is currently in constant development, still having some inconsistencies in certain situations, but it already has dozens of detections and is currently being used for testing on a PvP server, having great feedback from the project management.





Detection configuration:


As this is a closed-source anti-cheat, it has an external configuration file that can be reloaded at any time.

The configuration file currently has just over 200 configuration entries, where it is possible to parameterize exactly how each cheat that allows an external configuration should be detected.



Below are some of the configuration entries for better understanding:

Code:

cbug_speed_limit=
cbug_alert_count=
auto_cbug_speed_limit=
auto_cbug_alert_count=
armour_delay_check=
armour_alert_count=
health_delay_check=
health_alert_count=
driveby_delay_check=
fakekill_kill_flood_sequence_time=
fakekill_death_flood_sequence_time=
fakekill_kill_flood_alert_coun t=
fakekill_death_flood_alert_count=
fastrun_distance=
fastrun_distance_alert_count=
incoming_connection_alert_count=
incoming_connection_sequence_delay=
interior_delay_check=
interior_alert_count=
virtual_world_delay_check=
virtual_world_alert_count=
special_action_delay_check=
money_delay_check=

Security:

Any information in SA:MP can be easily manipulated, which can mess up the entire economy and the gameplay of others.

Currently, with the use of this anti-cheat, it is possible to recover correct information from the data of players who use cheats to manipulate them, such as health, armour, skin, weapons, ammo, attacked objects, etc., so that even when manipulating the information, it is not possible to maintain it during the data saving, thus creating an extra layer of validation in the information and ensuring the protection of each player's data against any type of external change.





Configuration control:

• Set when the anti-cheat should start for a specific player
  
• Set when the anti-cheat should stop for a specific player
  
• Set when the anti-cheat should pause or resume checking a specific cheat for a specific player
  
• Change and reload the anti-cheat settings at any time without having to restart the server or reload the filterscript
  

OS Compatibility:

All anti-cheat dependencies can be obtained for both Linux and Windows.
The anti-cheat is a filterscript, so it can be easily implemented like any other external script.


Game Mode Compatibility:

Since it is a robust anti-cheat with dozens of detections, an external configuration was created to adjust the detections according to the game mode or taste.
In a roleplay server, for example, the detections can be more sensitive, while for a PvP it is necessary to make weapon-related detections less sensitive or race-related detections less sensitive.
You can completely configure each detection as you prefer.


Detection approach:

The server is completely independent in deciding what to do about the detection.
For this, a library (evo_ac.inc) is provided containing all the information needed to apply the punishments and configurations.
Unlike most anti-cheats, this one generates an individual call in the respective callback informing more details about the detection.

Some callbacks:

Code:

AC_OnInvalidCameraCrasher(playerid, cam_mode)
AC_OnPlayerAmmo(playerid, old_ammo, new_ammo, weaponid)
AC_OnPlayerArmour(playerid, Float:old_armour, Float:new_armour)
AC_OnPlayerCBug(playerid, speed)
AC_OnPlayerAutoCBug(playerid, speed)
AC_OnPlayerCheckpoint(playerid)
AC_OnPlayerDamageFlood(playerid, damagedid, weaponid, damage_count)

Damage control:

With Evo Anti-Cheat's damage control, even using cheat, the player's life decreases and if it doesn't decrease (through RPC blocks) there is no problem, because the player's life and vest are The player's health is handled unilaterally, that is, the client's (player's) health and vest are just another visual piece of information, just like money. So, for example, if the player's health is zero on the server, but on his screen his health is full due to RPC blocking, it will be considered cheating and will call the functions corresponding to the cheat.

It is also possible to configure the damage in different situations:

• Body parts
  - For custom damage in 7 areas of the body
  
• Range
  - Automatically blocks shots fired outside the defined range
  
• Damage blocking in body parts
  - For custom damage blocking in 7 areas of the body
  
• Permission/block to give/receive damage
  - To allow and/or block damage given or received to players
