Read the whole reasonShow less

Why Suspicious? 2 antivirus engines flag it; nothing else confirms it.

Limited evidence · One sign points to a problem; nothing else confirms it.

Don't install it until you know where it came from

Treat the file as unverified; avoid installation until additional Android-specific scans or sandbox results become available.

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 the APK file. If you need the app, get it from Google Play instead.

If you already installed 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

A one detection from a major antivirus engine (Ikarus) labels the APK Trojan-Spy.AndroidOS.Banker, yet 73 other engines report clean and no sandbox execution or host-reputation results are available. The file was first seen on May 10, 2026 with medium prevalence and no external-intel hits.

Where this verdict could be wrong1 caveat
  • One detection from a major antivirus engine on an Android sample with no sandbox run and no external-intel corroboration leaves the malicious label unconfirmed.

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