DontStealMyData

An extra layer of protection for your Minecraft modpack. DontStealMyData checks your mods before the game starts and shows which files are worth reviewing and why. Whether you’ve added a new mod or downloaded a modpack, a warning gives you a chance to stop and check the file before continuing.

Malicious code can be disguised as an ordinary mod or update. In one documented incident, infected JAR files attempted to download additional code and access login data. CurseForge incident report

What it does

Scans mods before launch. Checks files in your mods folder, including nested JARs, for signs of access to account data, changes to startup settings, code downloads, and external program execution.

Explains what triggered the warning. Shows the mod’s name and the specific findings so you can choose whether to continue or exit and review the file.

Monitors activity during play. Logs unexpected child processes and changes to supported startup locations on Windows and Linux.

Runs scans locally. Your files and their hashes stay on your device.

How to read a warning

Legitimate mods can match some of the same patterns. Each warning shows what the scanner found so you can check whether the behavior makes sense for that mod and verify where you downloaded it.

DontStealMyData works alongside your other security measures and helps you make a more informed decision before launching. I plan to refine the detection rules as new threats emerge and players report false positives.
