Is rufus-4.15.exe safe?
No antivirus engine detected this verified Akeo Consulting executable, and the completed sandbox produced no malicious verdict or malicious child artifact.
The executable is verified as signed by Akeo Consulting, and 0 of 75 antivirus engines flagged it. One sandbox observed storage and USB-related activity without issuing a malicious verdict; packing and one defense-related technique merit caution, so obtain it from the official Rufus channel.

Before running
Run it only when it came from the developer's official site or another source you independently trust.
If you already ran it
Keep normal device protection enabled and stop if the file behaves unexpectedly.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
The executable is verified as signed by Akeo Consulting, and 0 of 75 antivirus engines flagged it. One sandbox observed storage and USB-related activity without issuing a malicious verdict; packing and one defense-related technique merit caution, so obtain it from the official Rufus channel.
The strongest evidence is the 0/75 antivirus result, including no tier-1 detections. The executable carries a verified Akeo Consulting signature that matches the curated trusted publisher. One completed sandbox observed activity consistent with a USB and storage utility and did not issue a malicious verdict, while neither of the two inspected child files was identified as malicious. High-entropy UPX-packed code and T1562.001 are legitimate caution points, but they lack corroboration from engines, sandbox verdicts, or external intelligence. A complete reputation check for contacted hosts was not available, although the recorded sandbox contact lists were empty.
What We Detected
None of 75 antivirus engines flagged the executable, and ten tier-1 engines reported no detection. The file has a verified signature from Akeo Consulting, which matches the curated trusted publisher associated with Rufus.
Threat Behavior
One completed sandbox run recorded storage, USB, system-discovery, and temporary-file activity without issuing a malicious verdict. T1562.001 was also recorded, which can indicate interference with security controls, but no persistence was observed and neither of the two inspected child hashes was identified as malicious. The executable contains high-entropy UPX-style code, a feature that can complicate static inspection but is not independently proof of malware. No complete contacted-host reputation result is available.
What To Do Now
Verify the Akeo Consulting signature in Windows and obtain the executable only from the official Rufus release channel. Keep endpoint protection enabled, and avoid running the file if its signature is invalid or its hash differs from the publisher-provided release.
Where this verdict could be wrong5 caveats
- behaviour.offensiveTechniques includes T1562.001, indicating activity associated with impairing defenses, although the completed sandbox did not issue a malicious verdict.
- peAnalysis.highEntropyCode=true and peAnalysis.likelyPacked=true, with the UPX1 section at entropy 8; packing can conceal code but is also used by legitimate compact utilities.
- Community annotations report suspicious or malicious automated assessments, but they have zero votes and are not corroborated by the 0/75 engine result or curated external intelligence.
- contactedHosts=null, so no complete host-reputation cross-check is available.
- signing.signerStats contains only 1 historical sample, limiting the strength of publisher-history evidence despite the verified trusted-publisher match.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/75 antivirus engines flagged the executable
- Verified signature from Akeo Consulting
- signing.trustedPublisher.matched=true
- No malicious sandbox verdict across one completed run
- No malicious child among two inspected dropped files
- peAnalysis.highEntropyCode=true and peAnalysis.likelyPacked=true
- behaviour.offensiveTechniques includes T1562.001
- contactedHosts=null, leaving host-reputation coverage incomplete
- signing.signerStats.totalSamples=1 provides limited historical depth
- Community annotations include uncorroborated suspicious automated assessments
Use the file only if downloaded from the official Rufus release channel and Windows confirms the Akeo Consulting signature. Keep endpoint protection enabled.
