Before opening or extracting
Treat the file as unverified and avoid opening or extracting it until more evidence is available.
If you already opened or extracted it
Run a full device scan. If its origin cannot be confirmed, delete this archive and use a fresh copy from a trusted source.

Intelligence
The saved assessment, checked against the scan evidence and recorded coverage.
The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
No antivirus engine flagged the file, but the sample is only hours old and has been seen by just one submitter. Without sandbox execution or deeper unpacking, the contents remain unknown.
The 75 engines returned a unanimous clean result, yet the file is classified rare_new and has no sandbox or contacted-host data. Similar ZIP files in the RAG set also received unknown verdicts due to low coverage. Because signing is not applicable and no runtime evidence exists, the analysis cannot move beyond unknown.
What We Detected
75 engines scanned the 46 MB ZIP; none reported malicious content. No code-signing metadata applies to this file type.
Threat Behavior
No sandbox execution occurred, so no process, network, or dropped-file behaviour is available. The file has not been observed contacting any hosts.
What To Do Now
Exercise caution with brand-new archives. Unpack the ZIP in an isolated environment or wait for additional scanner coverage before trusting the contents.
Where this verdict could be wrong1 caveat
- If the ZIP contains malicious content that no engine has yet seen, the zero-detection result could be a coverage gap rather than proof of safety.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- zero engine detections across 75 scanners
- rare_new classification
- no sandbox or runtime data
Treat the archive as untrusted until further analysis or additional detections appear.
Behavior
Plain-English impact first, then the observed runtime evidence.
Runtime behavior was not available
The report does not treat a missing runtime observation as a clean result.

How widely this file has been seen
Barely seen in the wild and first surfaced recently. That limits reputation evidence, but rarity alone is not proof of malware.

What to do now
There isn't enough information to give this file a clear rating.
Be cautious — an unknown rating is not the same as a clean bill of health.
Open or extract it only when its sender or download source has been independently verified.
When in doubt, don't open or extract it — or scan it again later once it's more widely seen.
