Eulen, Redengine, HamMafia: A 2024 Field Guide to FiveM Cheats

If you have ever stared at a Discord ticket reading "some guy is flying around in a tank," the cheat in question almost certainly came from one of three vendors. Eulen, Redengine, and HamMafia dominate the FiveM cheat market in 2024, and the differences between them shape which detection layers actually catch them.

This is not a how-to. It is a non-technical field guide aimed at server owners and admins so you can identify what is hitting your server, talk to your anticheat vendor sensibly, and recognise the marketing language that gets thrown around in support tickets.

The three big names

Eulen

Eulen is the closest thing to a household name in the FiveM cheat scene. It has been around for years, runs a public website, and operates on a recurring subscription model that resembles a SaaS product more than an underground tool. Pricing typically sits between $20 and $40 per month.

Feature-wise, Eulen is a Lua executor first and a mod menu second. It loads custom Lua into the FiveM client, lets the operator run arbitrary code, and ships pre-built scripts for common abuses (money drops, entity spawning, godmode, ESP). The user interface is approachable, which is part of why it spreads - a teenager with a credit card can be wreaking havoc inside ten minutes.

Redengine

Redengine is Eulen's direct competitor. Similar pricing, similar feature set, slightly different engineering philosophy. Where Eulen leans on a polished script catalog, Redengine leans on a more modular architecture that makes it easier for users to author custom modules.

From a detection standpoint, the two are mostly interchangeable. Anticheats that catch one usually catch both within a few weeks of each release.

HamMafia

HamMafia is the rougher product. Cheaper, less polished, with a community that openly traffics in stolen scripts and leaked resources. It attracts a different user profile than Eulen - more griefing, less "I want godmode for fun in roleplay," more "I want to break this server."

Detection is generally easier on HamMafia because it does less to evade signature scans. The trade-off is that HamMafia users are often more aggressive once they get in, so the cost of a missed detection is higher.

What they all have in common

All three rely on injecting code into the FiveM process. The injection vector varies, but the practical effect is the same:

• The cheat runs as part of the FiveM client, with full access to the Lua state and the rendering pipeline.
• It can call any client-exposed server event the running resources allow.
• It can read memory, including positions of other players, vehicle pointers, and ammo counts.
• It can hook the input handler to deliver aimbot snaps and trigger-bot fires.

How anticheats catch them

Each of these vendors gets caught in roughly the same ways:

• Memory signatures. The injected cheat leaves identifiable byte patterns in process memory. A client-side scanner that reads its own process can match those patterns and report.
• Hook detection. The cheat hooks game functions to install its features. A scanner that knows what the genuine game functions look like can detect that they have been altered.
• Behavioral anomalies. A player teleporting 40 metres in a frame is not a thing the legitimate engine produces. Server-side trust scoring catches this even when the client signature scan misses.
• Event-call shape mismatch. Cheats often call server events with argument patterns that a real client would not produce. Validating input shape and source is one of the cheapest server-side detections.

Practical takeaway for owners

If a player on your server is using one of these cheats, the most likely thing you will see in your logs is:

• A spike of TriggerServerEvent calls from one player.
• Position reports that imply movement faster than any vehicle.
• Inventory or balance changes with no transaction record on your end.
• Other players reporting visual cheats they cannot ignore.

A modern anticheat should be flagging at least one of those before your players notice. If yours is not, it is worth asking your vendor specifically which of Eulen, Redengine, and HamMafia they currently detect, and what their typical lag is between a new cheat release and a patched signature.

The cheat market evolves weekly. Knowing which vendor your problem player is using makes the conversation with your anticheat support faster. It is also a useful filter for evaluating new anticheats - any vendor that cannot tell you specifically how they handle these three is selling you marketing rather than detection.
