The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
All 74 engines returned clean results, including 17 tier-1 engines. The file is a 60 MB academic PDF on the history of mathematics with no sandbox data, no dropped children, and no external-intel matches.
The complete absence of malicious detections from every engine tier, combined with the academic filename pattern and lack of any external-intel or sandbox signals, indicates a benign research document. The file's age and low submission count are consistent with an obscure academic title rather than a threat. No contradictory evidence exists in the payload.
What We Detected
74 antivirus engines scanned the 60 MB PDF file; none flagged it as malicious or suspicious. Seventeen tier-1 engines explicitly marked it clean. Filename analysis flagged the document as matching research-tool patterns, which aligns with its academic title.
Threat Behavior
No sandbox execution data, dropped children, or contacted-host reputation results are available. External intelligence sources (CIRCL, MalwareBazaar, YARAify) returned zero matches.
What To Do Now
The file can be opened with a standard PDF reader. Keep endpoint protection enabled as a general precaution.
- 0/74 engines malicious
- 17 tier-1 engines clean
- academic filename pattern
- no external-intel hits
Open the PDF with any standard reader; no further action required.
