    Malware: it downloads and runs hidden code

    Found in this file: HubParkour-2.6.2.jar (14 Jan 2022). 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 HubParkour-2.6.2.jar from the plugins folder of your server.
    2. Check the plugins folder of your server for files you did not add.
    3. Check your other plugins.

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

    What it can do on your server

    Downloads and runs hidden codeMalware
    The code downloads code from a fixed address and runs it on the server. The address is hidden in the code, or this happens as soon as the code is loaded, as in the fractureiser malware.
    Hides a web addressWarning
    A web address (johnpluginhub.xyz) is encoded in its code, so it cannot be read in the file.
    Connects to the internet
    It has code that can go online. Found in the plugin's own code and in code libraries built into it. See Privacy
    Starts other programs
    It can start another program on your computer. Found in code libraries built into it.

    Why we show this: a plugin runs on your server like any program, so harmful code in it can take over the server. 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

    Privacy

    Sends nothing about you

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.8 to 1.18.1.

    We read its code without running it: it contacts 2 web addresses while the server runs.

    Why we show this: a plugin can send things about your server and its players over the internet, like their player name or their login. Contacting an address to check for updates or download files sends nothing about them. Not in the grade: sending data can be normal for what a plugin does.

    How we checked · Its one file read
    • Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.

    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.
