Verdict Suspicious

Analyzed , 25 days ago

Is Velostrap.dll safe? Treat it as suspicious.

Only 1 of the 69 antivirus engines that checked it flagged this file, and that result came from less reliable APEX while all 17 major antivirus engines remained silent.

Read the whole reasonShow less

Why Suspicious? One antivirus engine (APEX) flags it; 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.

The reasoning behind this verdict

Analyst conclusion

The antivirus pattern strongly favors a false positive: APEX supplied the only detection among 74 engines, with no major detections or family consensus. The sample is also widely encountered, with 1,879 sources and 2,415 submissions over 222 days. The completed host-reputation cross-check covered all distinct observed domains and IPs and found no known malicious or suspicious hosts, while no inspected child was identified as malicious. Because the file is unsigned and the similar-file history is mixed and based only on import-table fingerprint matches without signer corroboration, the evidence does not support a fully benign conclusion.

Where this verdict could be wrong3 caveats
  • The saved runtime mapping includes process injection and a rule-based indicating access to the Windows password store, activities that warrant caution even though the sandbox did not issue a malicious verdict.
  • The missing code signature leaves the executable without a verifiable publisher.
  • Three unknown file it created outcomes remain in the dropped-file summary, although none of the four inspected children was identified as malicious.

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: Checked whether it was running on a test computer.

  • Note: Talked to servers over the internet during the test run.

  • Note: Read basic details of the test computer, such as its Windows version.

  • Note: Loaded extra code modules while running.

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.

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.

I already downloaded and ran Velostrap.dll — 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 Velostrap.dll?
The SHA-256 fingerprint of Velostrap.dll is 6fd8ae68be5e103a957250c32eae71d6a5f6495ac85ffe7d5a278d1474fe154e, and its MD5 is 72a63c8f2b6314ca6c58c75f6d71d462. 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 Velostrap.dll?
This report reflects the scan on Oct 1, 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.
