Is PDF_225FFM_20260921080356.ZIP safe?
No antivirus engine detected a threat in this ZIP archive, although its recent appearance and lack of runtime analysis warrant ordinary caution.
All 75 antivirus engines were free of malicious or suspicious detections, including 17 tier-1 engines. However, the ZIP is newly observed, no sandbox run examined its contents, and one external rule check timed out, so extract and scan enclosed files before opening them.

Before opening or extracting
Open or extract it only when its sender or download source has been independently verified.
If you already opened or extracted 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.
All 75 antivirus engines were free of malicious or suspicious detections, including 17 tier-1 engines. However, the ZIP is newly observed, no sandbox run examined its contents, and one external rule check timed out, so extract and scan enclosed files before opening them.
The strongest evidence is the complete absence of malicious or suspicious detections across 75 antivirus engines. Seventeen tier-1 engines, including Microsoft, Kaspersky, ESET-NOD32 and BitDefender, reported no detection. No threat indicators appeared in MalwareBazaar or CIRCL, and no heuristic rules fired. Confidence is moderated because the archive was first observed today, has only four submissions, and has no completed runtime observation. Contacted-host reputation was not checked, while the YARAify query timed out, so those areas provide no complete result.
What We Detected
No malicious or suspicious result was reported by any of the 75 antivirus engines. All 17 participating tier-1 engines reported no detection, and neither MalwareBazaar nor CIRCL supplied a known threat match.
Threat Behavior
No completed sandbox observation is available, so the archive's runtime behavior and any enclosed files were not observed. No complete contacted-host reputation result is available, and the YARAify rule check timed out.
What To Do Now
Keep endpoint protection enabled. Because this ZIP is newly observed, scan the extracted contents individually and verify that the sender and expected document context are legitimate before opening anything inside.
Where this verdict could be wrong3 caveats
- The archive is 0 days old and has only 4 submissions, so the absence of detections may partly reflect limited exposure.
- YARAify timed out, leaving a gap in researcher-rule coverage.
- As a ZIP archive, it may contain files that were not dynamically executed or independently assessed in the available evidence.
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 detection
- 17 tier-1 engines reported no detection
- MalwareBazaar returned no match
- CIRCL returned no match
- No triggered heuristics or brand mismatch
- First observed 0 days ago
- Only 3 unique sources and 4 submissions
- No completed sandbox observation
- No complete contacted-host reputation result
- YARAify rule check timed out
- Archive contents were not separately described
Keep security protection enabled and scan every extracted file before opening it. If the archive was unexpected or came from an unverified sender, confirm its origin first.

What to do now
This file appears low risk based on the evidence available now.
- Recovery step 01
Open or extract it only when its sender or download source has been independently verified.
- Recovery step 02
A clean result reduces known risk, but it cannot guarantee that every new or targeted threat has been detected.
- Recovery step 03
Keep your antivirus and Windows updates switched on so you stay protected.
