Why we think so
5 points against it and 3 in its favour, checked against the scan evidence.
The reasoning behind this verdict
The T1003, T1055, and mappings warrant caution, but they lack target details, process-injection evidence, persistence, or other corroboration.
The strongest evidence is the absence of detections across 75 engines, including no major alerts. One completed sandbox run returned clean and recorded no injected process or persistence indicator. Although the runtime report mapped T1003, T1055, and T1485, those abstract mappings do not identify a target or demonstrate that the PDF performed those actions. No malware-specific YARA rule or malware-repository match corroborates the mappings. Confidence is moderated because the encrypted document is three dropped files lack saved verdicts, and no complete contacted-host reputation result is available.
What We Detected
None of the 63 antivirus engines that checked it flagged the PDF, including 17 major antivirus engines that reported no detection. No malware-specific YARA rule, named threat family, or malware-repository match was present.
Threat Behavior
The completed sandbox run returned clean and showed the document opening through Adobe Acrobat. It mapped T1003, T1055, and T1485, but did not identify a credential target, injected process, destructive action, or persistence mechanism. Those unsupported mappings are insufficient to establish hostile behavior. Three dropped files have no saved verdict, and no complete contacted-host reputation result is available.
What To Do Now
The document can be handled with ordinary caution. Keep the PDF reader and security software enabled and updated; if the file came from an unexpected sender or requests credentials, scripts, or external content, verify the source before interacting further.
Where this verdict could be wrong4 caveats
- The PDF is encrypted and only one day old, so static inspection and reputation history are limited.
- The sandbox mapped credential dumping, process injection, and data destruction techniques, although it supplied no target details and returned a clean verdict.
- Three dropped files have no saved verdict, leaving their nature unresolved rather than establishing them as harmful.
- No complete contacted-host reputation result is available, although the completed run recorded no sample contacts.
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 completed sandbox run returned clean and recorded no injected process or persistence indicator.
- No malware-specific researcher rules or malware-repository matches were found.
- The PDF is encrypted, which can limit static inspection.
- It was first observed on Oct 13, 2026 and has a single known submission.
- The sandbox mapped credential dumping, process injection, and data destruction techniques without enough detail to validate them.
- Three generated files have no saved classifications.
- No complete reputation check is available for contacted hosts.

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.

How widely this file has been seen
Barely seen in the wild and first surfaced recently. That limits reputation evidence, but rarity alone is not proof of malware.
