Genuine exploit researchers (e.g., from the Minecraft@Home community) name their projects neutrally: "TimingTestMod" or "PacketDebug." A file screaming "DUPETRIGGER" is either a honeypot or a 12-year-old’s script-kiddie attempt.

| Warning Sign | Why It’s Suspicious | |--------------|----------------------| | No documentation | Legit mods have READMEs, wikis, or mod page descriptions | | Random source | If it came from a file-sharing site (MediaFire, Dropbox, unknown Discord user), treat as malicious | | Requires disabling antivirus | Many fake mods instruct you to turn off real-time protection | | Claims “works on all servers” | Impossible – most servers have anti-dupe patches |

Upload to VirusTotal – though many fresh Minecraft mod viruses may have low detection rates initially.

If you already downloaded Dupe-Trigger-Mod-Fabric-1.20.1.jar and want to know what it actually does without infecting your PC:

  • Look for suspicious strings: Search for:
  • Check the fabric.mod.json: Does it declare unusual dependencies? Does it list an author with no GitHub history?

    • If you find any of the above, delete the file immediately and run a full antivirus scan (Malwarebytes + Windows Defender).
