Why we think so
0 points against it and 4 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 document, including every major antivirus engine. When opened in the sandbox it only launched Adobe Acrobat and its normal helper processes, with no injection into other programs and no network activity of its own.
None of the 63 antivirus engines that checked it flagged this PDF document, and all 18 major antivirus engines returned a clean result. The sandbox summary shows only Adobe Acrobat, its embedded browser component and its crash-log helpers running, which is what opening a PDF looks like. Two generic technique labels appeared without any matching activity, so they are not evidence of injection or credential theft. The only network contact was the analysis machine's own DNS resolver. The file has a short history, first seen on Jul 6, 2026, but nothing in the evidence points to hostile content.
What We Detected
None of the 63 antivirus engines that checked it flagged this PDF document. Every major antivirus engine, including Kaspersky, ESET, BitDefender and Microsoft, reported it clean. It was first seen on Jul 6, 2026 and has been submitted by a single source.
Threat Behavior
In the sandbox the document opened in Adobe Acrobat, which started its usual rendering and crash-reporting helpers and wrote ordinary font cache and temporary files. No code was injected into other processes, no persistence was created, and the only network contact belonged to the analysis machine's background DNS traffic. Two generic technique labels appeared in the summary without any matching activity behind them.
What To Do Now
The evidence supports opening this document normally. As with any PDF, keep your PDF reader updated and avoid enabling unusual prompts that ask to run programs or open external links.
Where this verdict could be wrong1 caveat
- The document has been submitted by only one source, so there is little community history, and our own static analysis of its contents was not available.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- No detections from any of the 74 antivirus engines, including all major antivirus engines
- Opening it in the sandbox started only Adobe Acrobat and its normal helper processes
- No code injection, persistence or outside network contact was observed
- The file is a PDF document whose name matches its actual type

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.
