Why we think so
3 points 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 the PDF, including the major antivirus engines, and the completed sandbox run returned clean.
The static scan produced no detection from any of the 75 engines, with all 17 major participants silent. One completed observation from the test run opened the document in Adobe Acrobat and did not produce a malicious sandbox assessment. Automated mappings included T1003, T1055, and T1485, but no injected process, persistence indicator, malicious child, or concrete credential-access action was recorded. All three observed sample domains received complete cache coverage without a malicious or suspicious match, while the public DNS contact was identified as sandbox background traffic. The file is and its ten generated files lack saved individual verdicts, so ordinary caution remains appropriate despite the strongly benign evidence.
What We Detected
None of the 63 antivirus engines that checked it flagged the PDF, including the 17 major antivirus engines that returned results. Malware-specific research rules and the external malware repository also produced no match.
Threat Behavior
The completed sandbox run opened the document with Adobe Acrobat and returned clean. Automated analysis mapped T1003, T1055, and T1485, but it recorded no injected target process, persistence mechanism, malicious child, or concrete credential-access event. Reputation checks covered all three observed sample domains and found no malicious or suspicious cache entries; the 8.8.8.8 contact was identified as analysis-environment background traffic.
What To Do Now
The evidence supports opening the document in a fully updated PDF reader with normal security software enabled. Because the hash is and ten generated files lack saved individual verdicts, avoid enabling embedded content or following unexpected links if the document behaves unusually.
Where this verdict could be wrong3 caveats
- The file is from only one submitter, so its wider reputation is not yet established.
- Sandbox mappings included T1003, T1055, and T1485; these are concerning labels, although the recorded process and injection details do not substantiate those actions.
- Ten generated files have no saved individual verdicts, leaving their identities unresolved even though none is currently identified as a malicious child.
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 PDF.
- All 17 major antivirus engines that returned results reported no detection.
- The completed sandbox run returned clean and showed the document opening in Adobe Acrobat.
- No injected process, persistence mechanism, or identified malicious child was recorded.
- Complete reputation coverage for the three observed sample domains found no malicious or suspicious matches.
- The exact hash is and has only one known submission.
- Automated sandbox mapping referenced credential dumping, process injection, and file deletion, though the underlying records did not confirm those actions.
- Ten generated files do not yet have saved individual verdicts.

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.
