No strong family consensus exists and files it created returned clean, leaving mixed signals.

Why Suspicious? 10 antivirus engines flag it; nothing else confirms it.

Don't open or extract 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 open or extract 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 opened or extracted 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

The file is a ZIP that extracts multiple PE components. Evidence from the test run maps to and T1562.001, and three major antivirus engines label the sample malicious. However, the major family consensus is weak, 14 major antivirus engines cleared it, and no file it created or cached host is confirmed malicious. Community notes reference several infostealer families, but prevalence is widely seen and long established. These conflicting indicators place the sample in the suspicious band.

Where this verdict could be wrong2 caveats
  • droppedChildren.hasMaliciousChild=false and contactedHosts.maliciousHosts.length=0 — no confirmed malicious child or cached host hit.
  • prevalence is widely seen and long established rather than rare and which can indicate a long-lived unwanted program or cracked utility rather than fresh malware campaign.

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