Is BAI - Notice of Supplementation 9-15-26.pdf safe?
No antivirus engine detected a threat in this PDF, though its recent appearance and lack of runtime observation warrant normal document-opening precautions.
All 74 antivirus engines were free of malicious or suspicious findings, including 15 tier-1 engines that completed analysis without detection. No curated external-intelligence matches were found, but the document is newly observed and was not executed in a sandbox, so it should still be opened with an updated PDF reader.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
All 74 antivirus engines were free of malicious or suspicious findings, including 15 tier-1 engines that completed analysis without detection. No curated external-intelligence matches were found, but the document is newly observed and was not executed in a sandbox, so it should still be opened with an updated PDF reader.
The strongest evidence is complete agreement across the antivirus network: 0 of 74 engines reported a malicious or suspicious result. Fifteen tier-1 engines completed analysis without detection, including BitDefender, ESET-NOD32, Kaspersky, and Microsoft. MalwareBazaar, CIRCL, and YARAify produced no matching intelligence, which provides additional static support but does not prove absence of hidden content. The five historical comparisons were also assessed as benign, although they match only by PDF file type and therefore carry little weight. Because no sandbox run or complete contacted-host reputation check is available, runtime activity cannot be characterized. The document is also newly observed, so ordinary caution remains appropriate despite the strong static results.
What We Detected
None of 74 antivirus engines reported the PDF as malicious or suspicious. Fifteen tier-1 engines completed analysis without detection, including BitDefender, ESET-NOD32, Kaspersky, and Microsoft. MalwareBazaar, CIRCL, and YARAify also returned no matching intelligence.
Threat Behavior
No completed sandbox observation is available because behaviour is null. The contacted-host reputation check was also not completed or saved, so no conclusion can be drawn about network contacts. Static metadata identifies a PDF containing an AcroForm, but no heuristic or malware-family evidence was reported.
What To Do Now
Open the document only if its source and expected subject matter make sense. Keep endpoint protection enabled, use a fully updated PDF reader, and avoid enabling unexpected actions, opening embedded attachments, or following unusual links.
Where this verdict could be wrong3 caveats
- The file is 0 days old and has only 1 recorded submission, so reputation-based assurance is limited.
- behaviour=null and contactedHosts=null — no completed runtime observation or host-reputation cross-check is available.
- The PDF carries the acroform tag; interactive form content expands the document's attack surface, although no engine identified a threat.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/74 engines reported malicious or suspicious findings.
- engines.tier1Malicious=0, with engines.tier1ReportedClean=15.
- externalIntel.malwareBazaar.hit=false.
- externalIntel.yaraify.ruleCount=0.
- brandMismatch is not detected and triggeredHeuristics is empty.
- Newly observed file: prevalence.timesSubmitted=1 and file.ageDays=0.
- No runtime evidence: behaviour=null.
- No completed host-reputation result: contactedHosts=null.
- Interactive PDF content indicated by file.tags containing acroform.
The document may be opened with an updated PDF reader if it came from an expected source. Keep endpoint protection enabled and avoid unexpected links, attachments, or interactive prompts.
