Analyzed , 1 month ago

Is zzz-mod-fixer-v3.1.exe safe? Treat it as suspicious.

An unsigned, rarely seen game-mod tool flagged only by generic labels from 4 of the 71 antivirus engines that checked it, with no hostile behaviour in the test run but too little…

Read the whole reasonShow less

Why Suspicious? 4 antivirus engines flag it; nothing else confirms it.

Limited evidence · One sign points to a problem; nothing else confirms it.

Don't run it until you know where it came from

If it came from a link, an attachment or a stranger, delete it.

What to do now4 steps

Some signs point to a problem, but nothing confirms it is harmful. Treat it with caution.

What to do

  1. Don't run it unless you're sure where it came from.

  2. Check where you got it: an unexpected attachment, a link someone sent you or a re-upload is a red flag.

  3. If you can't confirm where it came from, delete it. If you need the program, download it again from the publisher's own website.

If you already ran it

  1. Stop using it, run a full scan with your antivirus and watch for unexpected behavior or security alerts.

The reasoning behind this verdict

Analyst conclusion

Four of the 71 antivirus engines that checked it flagged this unsigned program, all with generic labels, including one machine-learning detection from Microsoft. The sandbox runs showed it unpacking game-mod assets, with no injection or suspicious network activity. However, it was submitted by only one source and has no publisher signature. Nobody has inspected its contents, so its safety cannot be confirmed.

Where this verdict could be wrong2 caveats
  • The sandbox run wrote only game-mod assets such as icons, character data scripts and a guide to a temporary folder, and showed no injection or network activity of its own. This looks like an ordinary Python-packaged hobby tool.
  • 17 of the major antivirus engines reported no detection, and the one detection from a major antivirus engine is a generic machine-learning label.

These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

What the test run showed

What the file did on a test computer

Confirmed in the test run

  • Moderate concern: Contains packed or scrambled code that is harder to inspect (common in installers too).

  • Moderate concern: Ran commands or a script on the test computer.

  • Moderate concern: Checked whether it was running on a test computer.

  • Note: Read the user name of the test computer.

  • Note: Listed the programs running on the test computer.

  • Note: Read basic details of the test computer, such as its Windows version.

  • Note: Looked through folders on the test computer (most installers do this).

Sandbox labels we could not confirm (common in safe files too)

  • Not confirmed: A sandbox rule tagged this run as code injection, but no injected program was recorded.

  • Not confirmed: A sandbox rule tagged this run as contacting a server, but no contacted host was recorded.

  • Not confirmed: Showed activity a sandbox rule links to file encryption; no ransomware behaviour was confirmed.

  • Not confirmed: A sandbox rule tagged this run as weakening security settings; no setting change was recorded.

This file was run on a test computer (a sandbox), not on yours. Labels we could not confirm are listed so you can see them, but they are not treated as evidence against the file.
