Read the whole reasonShow less

Why Suspicious? 2 antivirus engines flag it, but no major engine agrees and a community rule for known malware matched it.

Moderate evidence · More than one sign points to a problem, but nothing confirms it is harmful.

Don't install 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 install 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 installed 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

Only 2 of the 70 antivirus engines that checked it flagged this unsigned installer, and none of the major antivirus engines did. Two community pattern rules for droppers and ransomware matched it, which keeps it from being cleared. In the sandbox runs it installed LuaTools into the user profile and checked GitHub for updates, without recorded injection or a malicious run result.

Where this verdict could be wrong3 caveats
  • Activity in the test run looks like an ordinary self-updating installer: it unpacks the app into the user profile, checks GitHub for releases and sends analytics, with no recorded injection target or malicious run.
  • The two malware-specific pattern rules are community-written and broad (one simply named for ransomware), so they may match benign strings in a large .NET bundle.
  • None of the 18 major antivirus engines flagged the file, and it has been submitted by 765 different sources.

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: Downloaded a file during the test run.

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

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

  • Note: Talked to servers over the internet during the test run.

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

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: Showed activity a sandbox rule links to file encryption; no ransomware behaviour was confirmed.

  • Not confirmed: A sandbox rule tagged this run as creating a service; no new service was recorded.

  • Not confirmed: A sandbox rule tagged this run as setting up auto-start; no auto-start entry 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.
