what is antirat fr?

AntiRat is a security mod for Minecraft, built on the Fabric mod loader, that tries to catch other mods designed to steal a player's account or spy on their computer, commonly called stealers or remote access trojans. It only runs on the player's own game client, not on a server, and installation is a single step: dropping the correct file into the mods folder for your Minecraft version, with nothing else required. It works in layers. Before other mods even finish loading, it scans their code and files for suspicious signs, things like hidden nested files, disguised executable code, or capabilities related to reading credentials and sending data out to the internet. The README is clear that no single suspicious trait is enough to trigger action. It looks for combinations, such as something capable of reading login credentials paired with something capable of sending data elsewhere. Once the game is running, it keeps watching. If a mod tries to access session or login data, AntiRat checks where that request is actually coming from and compares it against a verified fingerprint of that mod's file taken at startup. Trusted mods are let through normally, while anything suspicious, altered, or unrecognized gets fake, empty data instead of the real thing. It applies similar watching to file access, network connections, and attempts to launch other programs, covering common places stealers try to read from, like browser data or messaging app files, and common ways they try to send data out, like webhooks or direct network sockets. It is explicit that it does not store the actual credential values or file contents it detects, only sanitized summaries of what happened. When something is confirmed dangerous, AntiRat moves the offending file into a quarantine folder rather than deleting it outright, and disables anything else that depended on it, so the next time Minecraft starts things load cleanly. Players can also run in game commands to list, inspect, manually scan, or quarantine specific mods themselves. The project is released under the MIT license.
