Is C0345.pdf safe?
None of 75 antivirus engines detected this PDF, and available external intelligence produced no malware-family, research-rule, or known-bad sample match.
The PDF drew no malicious or suspicious detections from 75 antivirus engines, including no tier-1 alerts. Available threat-intelligence checks also returned no matches, although no completed sandbox observation or contacted-host reputation check is available.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
The PDF drew no malicious or suspicious detections from 75 antivirus engines, including no tier-1 alerts. Available threat-intelligence checks also returned no matches, although no completed sandbox observation or contacted-host reputation check is available.
The strongest evidence is unanimous antivirus silence: 0 of 75 engines flagged the PDF, with 16 tier-1 engines reporting no detection. No malware family was identified, and available CIRCL, MalwareBazaar, and YARAify checks produced no matches. Five prior PDF samples with file-type similarity also received safe decisions, though file-type matching alone is weak corroboration. Code signing is not meaningful for this PDF, so its absence does not count against it. No completed runtime observation or complete contacted-host reputation result is available, which prevents absolute assurance about embedded behavior.
What We Detected
None of 75 antivirus engines marked the PDF as malicious or suspicious. Tier-1 products including BitDefender, Kaspersky, Microsoft, ESET-NOD32, and Fortinet reported no detection, and no engine supplied a malware-family label.
Threat Behavior
No completed sandbox observation is available, so runtime behavior was not observed. The contacted-host reputation cross-check was also not completed or saved, and therefore no complete network-reputation conclusion can be drawn. Available CIRCL, MalwareBazaar, and YARAify checks returned no matching intelligence.
What To Do Now
The evidence supports ordinary handling of this PDF. Keep endpoint protection enabled, use an updated PDF reader, and exercise additional caution if the document arrived unexpectedly or asks you to open links, attachments, or enable unusual features.
Where this verdict could be wrong3 caveats
- behaviour=null, so no completed runtime observation is available to assess embedded PDF actions or execution behavior.
- contactedHosts=null, meaning no complete contacted-host reputation result is available.
- file.ageDays and prevalence are unavailable, limiting reputation and distribution context.
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.
- 16 tier-1 engines reported no detection.
- No MalwareBazaar, CIRCL, or YARAify match was found.
- No heuristic rule fired.
- Five file-type-similar PDF samples previously received safe decisions.
- No completed runtime observation is available.
- No complete contacted-host reputation result is available.
- File age and prevalence data are unavailable.
The file can be handled normally with endpoint protection kept enabled and the PDF reader fully updated. If its source is unexpected, verify the sender before following embedded links.

What to do now
This file appears low risk based on the evidence available now.
- Recovery step 01
Open it only when its sender or download source is one you independently trust.
- 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.
