Before opening
Open it only when its sender or download source is one you independently trust.
If you already opened it
Keep normal device protection enabled and stop if the file behaves unexpectedly.
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 engines flagged the PDF. Sandbox execution produced no malicious indicators and no malicious dropped children were found. The file is newly observed but shows no signs of malice.
All 75 engines returned clean results with zero tier-1 detections. The single sandbox run observed only benign Acrobat Reader activity and wrote no malicious files. External intelligence sources returned no hits. While the file is rare and newly submitted, the complete absence of malicious signals across multiple independent sources supports a clean classification.
What We Detected
75 antivirus engines scanned the PDF with zero malicious detections. Sandbox analysis showed only standard Acrobat Reader processes writing temporary cache files.
Threat Behavior
No offensive MITRE techniques, no malicious network contacts, and no malicious dropped children were observed. External threat-intel sources returned no matches.
What To Do Now
The file can be opened normally. Keep endpoint protection enabled and scan any future PDFs from unknown sources.
- Zero detections across 75 engines
- Clean sandbox verdict
- No malicious dropped children
Open the PDF with standard precautions; no further action required.
