FiveM Anti-Cheat: Protecting Your Server from Hackers

If your server is public and growing, you will eventually see a cheater. The question is whether you will catch them in five minutes or after they have ruined a week's worth of RP.

The honest landscape

There is no silver bullet anti-cheat for FiveM. Every tool catches some categories of cheats and misses others. Cfx's built-in OneSync server-authority is your strongest defense by default — most free menus simply don't work against a properly configured OneSync Infinity server.

Layered defense beats a single tool

Combine three things: server-authoritative event handlers, an active anti-cheat (FiveAC, BadgerAC, or a paid alternative), and a logging script that flags suspicious admin commands or impossible economy gains. Each layer catches a different failure mode.

Code your events defensively

The most exploitable category isn't menu hackers — it is poorly written scripts that trust client input. Any event that gives money, items, or moves a player should be validated server-side. TriggerServerEvent('myjob:pay') with no arguments and no validation is a payday for any kid with a basic script executor.

Bans that actually stick

Ban by hardware ID (HWID) when possible, not just steam hex or license. Discord IDs are useful as a softer signal. Be careful with IP bans — players on shared CGNAT will accidentally take down innocent users.

Logs are your best friend

A boring logs channel in Discord that posts every admin command, every large money transfer, and every kick is worth more than any anti-cheat. You will catch insider abuse and bugs in the same dashboard.

Wrapping up

Anti-cheat is a process, not a product. Configure your stack, write defensive code, log aggressively, and respond fast when reports come in. The cheater playing a long game will give up and find a softer target.
