Is Download (81).mp4 safe?
No antivirus engine detected this MP4, and external intelligence found no matching threat indicators, although the newly observed hash lacks runtime analysis.
All 75 antivirus engines returned no malicious or suspicious detection, including 17 tier-1 engines. The sample also has no external-intelligence hits, but it was only recently observed and no sandbox or complete contacted-host assessment is available.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
All 75 antivirus engines returned no malicious or suspicious detection, including 17 tier-1 engines. The sample also has no external-intelligence hits, but it was only recently observed and no sandbox or complete contacted-host assessment is available.
The strongest evidence is the unanimous antivirus result: none of 75 engines flagged the MP4, and all 17 reporting tier-1 engines found no detection. Its MP4 type makes code signing inapplicable, so an absent signature does not count against it. MalwareBazaar, CIRCL, and YARAify supplied no corroborating threat intelligence. Five prior MP4 samples received clean assessments, although those are only broad file-type matches and therefore carry limited weight. The remaining uncertainty comes from the hash being newly observed and from the lack of completed runtime and contacted-host analysis.
What We Detected
None of 75 antivirus engines flagged the file as malicious or suspicious. This includes 17 tier-1 engines, and no engine supplied a malware-family label. MalwareBazaar, CIRCL, and YARAify also returned no matching threat intelligence.
Threat Behavior
No completed sandbox observation is available, so execution or media-parser behavior was not observed. A complete contacted-host reputation result is also unavailable. The file is identified as an MP4, and code signing is not meaningful for this format.
What To Do Now
The available static evidence supports opening the file with a fully updated media player while keeping endpoint protection enabled. Because the hash is newly observed, obtain it again from a trusted source if its origin is uncertain or if the player reports malformed content.
Where this verdict could be wrong3 caveats
- prevalence.classification=rare_new with 1 submission from 1 source, so the hash has virtually no established history.
- behaviour=null and contactedHosts=null, leaving runtime behavior and contacted-host reputation unverified.
- similarHashes entries are filetype-only matches, so they provide weaker support than signer or close binary similarity.
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 reported a malicious or suspicious result
- 17 tier-1 engines reported no detection
- No MalwareBazaar, CIRCL, or YARAify hit
- 5/5 filetype-matched prior samples received safe verdicts
- No brand mismatch or suspicious filename heuristic was present
- Newly observed hash with only 1 submission from 1 source
- No completed sandbox runtime observation
- No complete contacted-host reputation assessment
- Similar-file history is based only on broad MP4 file-type matches
Open it only with an updated media player and keep endpoint protection enabled. If the download source is unfamiliar, verify the source or obtain a fresh copy before use.
