Verdict Suspicious

Analyzed , 12 days ago

Is OMNITUBE_Setup_1.4.2.exe safe? Treat it as suspicious.

A backdoor detection from a major antivirus engine and one hostile sandbox result raise concern, but sparse detections, a clean sandbox run, and non-hostile contacts prevent…

Read the whole reasonShow less

Why Suspicious? 4 antivirus engines flag it and one sandbox test run rated it malicious while another found nothing.

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

Four of the 69 antivirus engines that checked it flagged this unsigned, installer, including Kaspersky with a generic Python backdoor label. One sandbox reported hostile activity and mapped several offensive techniques, while another sandbox was clean and the fully covered host check found no suspicious destinations, leaving substantial uncertainty.

Where this verdict could be wrong5 caveats
  • Only 4 of the 69 antivirus engines that checked it flagged the file, and 16 major antivirus engines did not flag it; there is no major family consensus.
  • The second sandbox returned clean, so runtime verdicts do not agree.
  • All distinct observed non-background contacts were covered by the host-reputation check, with no malicious or suspicious host matches.
  • No malware-specific YARA rules matched, and none of the ten dropped files has a saved malicious verdict.
  • The observed Python environment setup and package-download activity could belong to a legitimate application installer.

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

  • High concern: Encrypted files on the test computer, as ransomware does.

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

  • Moderate concern: Downloaded a file during the test run.

  • Moderate concern: Unpacked hidden content while it ran.

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

  • Moderate concern: Hid files or windows on the test computer.

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

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 weakening security settings; no setting change was recorded.

  • Not confirmed: A sandbox rule tagged this run as changing how Windows loads code; nothing confirms it.

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.
