The reasoning behind this verdict

Analyst conclusion

No legitimate purpose justifies this behavior; let your antivirus remove it now.

Where this verdict could be wrong3 caveats
  • droppedChildren.hasMaliciousChild=false (10 unknown); no behaviour.hasMaliciousSandboxVerdict — children may be undetected.
  • tier1FamilyConsensus 'script' with only 2 agreeingEngines (not strong); some generic labels like Sophos 'Mal/Generic-S'.
  • contactedIps '162.159.36.2' resolves to Cloudflare CDN (benign), weakening direct-IP a control server heuristic.

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

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

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

Threat context

How trojans work

A trojan pretends to be something useful or harmless so that you run it. Once open, it does its real job in the background, from stealing data to opening a back door or downloading more malware.

Bottom line:The disguise is the whole trick, so a trustworthy-looking name or icon means nothing.
