Verdict Suspicious

Analyzed , 1 month ago

Is Plutonium.Updater.App.exe safe? Treat it as suspicious.

The engine result alone is weak: 3 of 75 detections, none from major antivirus engines, and only one Quasar label.

Read the whole reasonShow less

Why Suspicious? 3 antivirus engines flag it, but no major engine agrees; 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.

MT AI Engine · Verdict analysis

The reasoning behind this verdict

Analyst conclusion

Three of the 70 antivirus engines that checked it flagged the sample, with no major detections or family consensus, so the Quasar identification is not established. The executable is unsigned and appears packed, and ten researcher YARA rules matched it, adding meaningful static corroboration. Its age, broad prevalence, lack of a malicious sandbox verdict, and absence of confirmed malicious files it created reduce certainty. Host-reputation coverage was incomplete because only one host was inspected despite numerous observed IP and URL contacts.

Where this verdict could be wrong5 caveats
  • Sixteen major antivirus engines, including BitDefender, Kaspersky, ESET-NOD32, and Microsoft-class peers represented in tier1ReportedClean, did not flag the sample; no major family consensus exists.
  • No dropped file is known to be malicious, but all 10 children retained unknown verdicts, so this does not establish that the downloaded components are benign.
  • No sandbox returned a malicious verdict, despite the recorded offensive-technique mappings.
  • The file is old and widely submitted: it was submitted 35788 times and it has 3723 distinct submitters.
  • contactedHosts.inspected=1 does not cover the many distinct behaviour.contactedIps and contactedUrls, so host reputation remains incomplete.

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: Listed the programs running on the test computer.

  • Note: Deleted files or logs during the test run (installers often clean up after themselves).

  • 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: A sandbox rule tagged this run as recording keystrokes; no keylogging was confirmed.

  • 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 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.
