Stopping FiveM Trigger Exploits: How We Solved It with Trigger Finder

If you've run a FiveM server for any length of time, you've met this problem: a player with a cheat menu starts handing themselves money, spawning vehicles, or filling their inventory with items-without ever touching the intended UI. They're not breaking the game engine. They're calling your server's networked events directly.

This is the single most common way FiveM servers get exploited, and "secure your events" is the standard advice. The trouble is that advice assumes you already know which of your events are exposed. On a real server running dozens of resources, almost nobody does. This post explains how trigger exploits work, why they're so hard to fix by hand, and how we turned the whole problem into a tool: Trigger Finder.

What a trigger exploit actually is

In FiveM, scripts communicate across the client–server boundary using networked events. A client calls TriggerServerEvent and the server runs whatever handler is registered for that event name. That's exactly how legitimate gameplay works-and it's exactly what a cheat abuses.

A cheat menu can fire any networked event your server registers, with any arguments it wants. If a resource has a server event that adds money, gives an item, or spawns a vehicle, and that event trusts the values the client sends, the cheater just calls it directly:

-- Vulnerable: the server trusts whatever the client sends
RegisterNetEvent("shop:buyItem", function(item, amount)
    local ply = FX.GetPlayerFromSource(source)
    -- No price check, no validation - the client controls everything
    ply.addItem(item, amount)
end)

-- A cheat just calls:
-- TriggerServerEvent("shop:buyItem", "gold_bar", 9999)

Why it's so hard to fix by hand

The fix for any single event is well understood-validate server-side, never trust client input. We cover the exact patterns in our FiveM Lua Event Security Guide. The hard part isn't fixing one event. It's knowing where all of them are.

A typical roleplay server runs anywhere from 50 to 300+ resources, many of them third-party scripts you didn't write. Each one can register dozens of networked events. That's potentially thousands of events, scattered across files you've never opened. You can't secure what you can't see, and no one is going to manually read every resource looking for a stray addMoney handler.

How we solved it

Rather than just publishing more documentation, we built the audit directly into the ZeroTrust panel. The idea was simple: if the dangerous part of a server is its event surface, then every owner should be able to see that entire surface at a glance, ranked by risk, with a direct path to each one.

• Find everything - automatically map every event and trigger across all of your resources, not just the ones you remember.
• Rank by risk - surface the handlers cheaters actually target (money, items, weapons, vehicles, jobs, outbound HTTP) so you start where it matters.
• Go straight to the source - point you to the exact resource, file, and line so fixing it takes seconds, not an afternoon of grepping.

Meet Trigger Finder

Trigger Finder is a scanner built into the ZeroTrust dashboard. You run a server-initiated scan, and it reads through your resources and pulls out every event and trigger it finds-tagging each one with its resource, file, line number, side (client or server), and event name.

It maps your entire trigger surface

Instead of guessing, you get a complete, searchable inventory of every networked event your server exposes. Each trigger is recorded with where it lives and which direction it flows-Client → Server, Server → Client, Client → Client, or Server → Server-so you can immediately see which ones are reachable by a malicious client.

It flags the dangerous ones automatically

• Move money: addMoney, giveMoney, addAccountMoney, addBank, giveBank.
• Grant items: giveItem, addItem, addInventoryItem.
• Hand out weapons: giveWeapon, addWeapon.
• Spawn vehicles: addVehicle, spawnVehicle.
• Change jobs: setJob, setPlayerJob.
• Create pickups or send outbound requests: createPickup, PerformHttpRequest, SendWebhook.

The result is a risk breakdown for your whole server: how many triggers are safe versus critical, which resources contain the most dangerous events, and how everything splits between client and server.

It sorts everything into categories

• Money Related, Add/Give Item Events, and Inventory Events for the economy.
• Vehicle Spawn and Job Change for common roleplay exploits.
• RegisterNetEvent and AddEventHandler so you can spot events registered in the wrong context.
• Dynamic Events for everything that doesn't fit a known pattern.

It takes you to the exact line

Every finding links back to its resource → file → line, with a code-context view so you can read the trigger in place. When Trigger Finder flags a dangerous addItem handler, you know exactly which script and which line to harden-no hunting required.

It's tunable to your server

Every server is different, especially with custom frameworks. You can configure your own keywords and dangerous-event list, so Trigger Finder flags the function names that matter for your scripts, not just the defaults.

From finding to fixing

Trigger Finder tells you what to secure. Closing the gap is the next step: validate every flagged event server-side, retrieve values using server-side methods instead of trusting client input, and check the player's state, position, and permissions before acting. The full patterns-plus the FXServer security convars worth enabling-are in our FiveM Lua Event Security Guide.

Stop guessing about your attack surface

You can't defend an attack surface you've never seen. Trigger Finder turns the vague advice of "secure your events" into a concrete checklist generated from your actual server-so you know precisely what's exposed and where to fix it.
