    Why no grade

    Malware was found in one of its files, so it has no grade. See Security

    In-game changes

    Adds no new blocks, items or other content.

    Keeps all of vanilla Minecraft's textures, models and sounds.

    Malware: it steals your Minecraft session and sends it to a server

    Found in this file: slimgario-1.0.jar (9 Nov 2019). Its download is blocked.

    We found this in its code, read without running it.

    Because of this malware, it has no grade.

    If you installed it

    1. Remove slimgario-1.0.jar from your mods folder.
    2. Run a full scan with your antivirus.
    3. Sign out of all sessions and change your Microsoft account password.
    4. Check your other mods.

    Another project by this creator, DASMTTIISE, contains malware according to our analysis.

    What it can do on your computer

    Steals your Minecraft session and sends it to a serverMalware
    One part of the code reads saved logins, tokens or your game session, and a linked part sends data to a fixed address.
    Sends your Minecraft login tokenWarning
    Sends your Minecraft login token to an address built at run time, not to Mojang. With it, someone can use your account.
    Connects to the internet
    It has code that can go online. It contacts 1 web address. See Privacy

    Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.

    How we checked · The latest file checked
    • FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.
      1 latest file. It is not for a recent Minecraft version, so the answer above is about it. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
    • Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.

    AI

    No sign so far that AI was used to make it

    We looked for AI tools in its description, files and images and found none.

    We have not read its changelogs yet.

    No sign of AI in the game

    We found no AI service, AI library or AI model file in its code.

    Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
