Fast Hack Detector

Detects speed hacking, rapid firing, and frequent nickname changes.

If you want full protection from cheats and false bans, you can’t do without this plugin!
Here’s why:

Imagine there are network lags or your server is under attack.

Other plugins can generate a lot of false bans!

• How laggers get banned – first they freeze, and when their connection restores, they suddenly teleport. Fast Hack Detector has a special algorithm that blocks speed hacks in these cases. If there are no updates from the player for a tenth of a second or longer, once their connection restores and they exceed the allowed distance, they will be returned to their previous position.
• Fast Hack Detector also accurately analyzes the network connection, allowing reduction of detections if the player has high ping, packet loss, or fluctuating ping.

Blocking isn’t enough – speed hacks almost always come with aim hacks and other cheats!

Such anti-cheats detect speed by counting FPS and/or calculating speed from coordinates obtained at set intervals.

• FPS-based detection can be of two types:
• Bans if FPS exceeds a certain value – can lead to false bans if the player increased FPS.
• Bans if FPS is above the player’s own average (the player themselves) – some cheats always increase FPS.

FPS-based anti-cheats may fail to detect minor speed hacks!
Additionally, they may ban players who didn’t move or shoot at all!

• In anti-cheats using coordinates, either moving objects are not accounted for or not all interactions between player and objects are considered. For example, a player in an elevator or pushed by a train. Fast Hack Detector accounts for all objects and interactions between players and objects.

Test map - DOWNLOAD - check your anti-cheat!
This map is designed to test anti-cheats that calculate player speed using coordinates obtained at intervals.
It contains many objects that could cause false bans in such anti-cheats.

• Do not be an admin during testing, as immunity may apply.
• Ensure no bans occur for players with FPS over 100 or fluctuating FPS.

• Add -dev to the game launch shortcut, for example: C:\Counter-Strike 1.6\hl.exe -dev
• In console, type developer "1"
• Bind two keys, e.g., bind j "fps_max 20; fps_modem 20" and bind k "fps_max 200; fps_modem 200"
• Press these keys while interacting with objects.

Features:

• If a player uses both speed hacks and rapid fire simultaneously, they will be banned twice as fast. Detections from speed and rapid fire are cumulative.
• Each weapon has its own allowed firing rate; you cannot shoot an AWP as fast as an AK, which other anti-cheats allow. (Maximum allowed firing rate for each weapon is configurable.)
• Detections gradually reset over time (configurable).
• The plugin checks movement and firing speed, counting FPS as detections. This ensures false positives give fewer detections than a cheater. With slight speed hacks, FPS reaches ~150; with strong hacks, ~500.
• Player’s game client is considered. Newer patches reduce cheat compatibility, lowering the probability of cheating. For patch 48, emulators are harder to bypass. Older patches have different detection thresholds.

• For banning with protocol 47 without an emulator, a minimum number of detections is required.
• For protocol 48 and with emulator, more detections are required; for Steam clients, even more (each client type has configurable detection settings).
• You can disable banning Steam clients and only log detections (logged in fhd_steam.log).
• At least 2 detections are required for a ban (configurable) – additional protection against false positives.

Use with caution alongside plugins that speed up, move, or teleport players!
