Verdict Suspicious

Analyzed , 3 months ago

Is ClassicPaint.zip safe? Treat it as suspicious.

ZIP installer shows direct-IP network activity and offensive MITRE techniques despite zero AV detections.

Why Suspicious? Direct-IP a control server without DNS resolution.

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

Don't open or extract it until you know where it came from

Treat as suspicious; obtain Classic Paint from an official channel and avoid running this archive.

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.

Not sure what to do?

MT AI Engine · Verdict analysis

The reasoning behind this verdict

Analyst conclusion

Sandbox behaviour includes 5 offensive techniques, direct-IP contacts to 18 addresses, and persistence indicators. Mixed signals from unsigned status, rule-based trigger, and community tags keep the file in suspicious territory.

Where this verdict could be wrong3 caveats
  • Zero engine detections and widely seen and long established prevalence suggest benign installer, yet direct-IP a control server pattern and offensive MITRE techniques remain unexplained by a legitimate paint application.
  • Community comments label the sample #bootkit #stealer #spyware, but these are researcher annotations without engine or sandbox corroboration.
  • ZIP containing an Inno Setup installer (ClassicPaint-1.1-setup.exe) could be a legitimate re-packaged utility or a delivery vehicle for the observed persistence and data-access behaviour.

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

Questions & answers

Short answers to the 6 questions people ask most about this file.

Is ClassicPaint.zip safe, or is it malware?
ClassicPaint.zip is rated Suspicious: some signs point to a problem, but nothing confirms it is harmful. No antivirus engine flags it; the caution comes from other evidence, such as who made it, how widely it is used or what it did in a test run. Don't open or extract it unless you're sure where it came from. If you need what's inside, download it again from the original website.
What is ClassicPaint.zip?
ClassicPaint.zip is a ZIP archive, about 4.3 MB. VirusTotal first saw it on Dec 8, 2022.
How many antivirus engines detected ClassicPaint.zip?
None of the 66 antivirus engines that checked it flag ClassicPaint.zip. A clean antivirus result is not proof of safety; the caution comes from other evidence, such as who made it, how widely it is used or what it did in a test run.
I already downloaded and opened or extracted ClassicPaint.zip — what should I do?
No infection is confirmed: the rating is a caution, not a malware finding. 1) Check where it came from. If you can't confirm the source, delete it. 2) Run a full scan with your security software. 3) If the scan finds something, follow its removal steps and change passwords you typed on the device since then.
What is the SHA-256 hash of ClassicPaint.zip?
The SHA-256 fingerprint of ClassicPaint.zip is fe64c7ab3ef7daf4fb576ee2a1d9a7c2aec2ce01154293f31e51a5dd4a72b4d2, and its MD5 is b87c81e588571d81438144b903d2c317. Two files with the same SHA-256 are identical, so use it to check you have exactly this file, not just one with the same name.
How up to date is this analysis of ClassicPaint.zip?
This report reflects the scan on Jul 9, 2026. A file's fingerprint never changes, but antivirus engines keep learning, so a rating can change later. To get a newer result, scan the file again: we refresh the antivirus results when the saved ones are out of date.
