Why we think so
1 point against it and 5 in its favour, checked against the scan evidence.
The reasoning behind this verdict
None of the 63 antivirus engines that checked it flagged this PDF, including all 17 major antivirus engines. When opened in a sandbox it launched Adobe Acrobat and its usual helper processes, contacted only Adobe and system hosts, and the run finished clean.
None of the 63 antivirus engines that checked it flagged the file, and every major antivirus engine that reported returned no detection. The single sandbox run was clean, and the processes observed belong to Adobe Acrobat DC and Windows Installer, as expected when a PDF is opened. Every contacted host was checked against our reputation cache with no malicious or suspicious results. The document uses auto-actions and forms, which are common in interactive PDFs and showed no abuse here.
What We Detected
No detections from any of the 75 engines, including major antivirus engines such as Kaspersky, ESET, Microsoft and BitDefender. No hits in external malware intelligence or YARA rule feeds. The file has been seen from 73 sources over about eight months.
Threat Behavior
In one sandbox run the PDF opened in Adobe Acrobat DC, which started its crash-reporting and logging helpers and Windows Installer. Network contacts went to an Adobe service host and normal system background traffic; all were checked against our host reputation data with nothing flagged. The document contains auto-actions and form fields, which are standard in interactive PDFs.
What To Do Now
The document can be opened normally. As with any PDF, keep your PDF reader updated and keep your antivirus protection enabled.
Where this verdict could be wrong2 caveats
- The sandbox mapped techniques such as process injection and credential dumping, though the observed processes are Adobe Acrobat's own components and no injected process was recorded.
- The PDF carries auto-action and interactive form features, which can be abused, but nothing in this sample's runtime showed abuse.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- None of the 63 antivirus engines that checked it flagged the file.
- The sandbox run finished clean and showed only Adobe Acrobat and Windows components.
- All contacted hosts were checked with no malicious or suspicious results.
- No matches in external malware intelligence feeds.
- Seen from 73 different sources over about eight months.
- The document uses auto-run actions and interactive forms, features that are sometimes abused in malicious PDFs.

Signatures and behavior heuristics
Low-severity pattern matches — worth noting but not on their own cause for alarm.
VirusTotal's sandbox summary maps this run to MITRE T1055 (Process Injection), but no injected process of the sample's own was recorded (the analysis VM's own WMI adapter, crash handlers and Chrome updater are not counted). VirusTotal maps T1055 on about half of all files no engine flags, so the mapping alone is not evidence of injection.
EvidenceT1055 (sandbox MITRE mapping)VirusTotal's sandbox summary maps this run to MITRE T1003 (OS Credential Dumping), but no process targeting LSASS or another credential store was recorded. VirusTotal maps T1003 on clean files more often than on detected ones, so the mapping alone is not evidence of credential theft.
