Why we think so
1 point against it and 3 in its favour, checked against the scan evidence.
The reasoning behind this verdict
When opened in a sandbox, it only launched Adobe Acrobat and its usual helper processes, with no network contacts or process injection recorded. It is rarely submitted, so stay alert to any links or requests it contains.
The sandbox runs show Adobe Acrobat opening the file along with its crash reporter and log helpers, which is ordinary viewer behaviour. Two technique labels for injection and credential access were mapped without any matching activity, and such labels routinely appear on clean files. The document was first seen on Aug 25, 2026 and submitted by only two sources, and our own static check of its contents was not available, so its links and text were not reviewed.
What We Detected
None of the 63 antivirus engines that checked it flagged this PDF document. It was first seen on Aug 25, 2026 and has been submitted by two sources.
Threat Behavior
In the sandbox runs, the document opened in Adobe Acrobat, which started its normal crash-reporting and logging helpers. No other process was targeted, no network contacts by the document were recorded, and no files were dropped. Labels suggesting injection or credential access were mapped without any matching activity and are common on clean files.
What To Do Now
The file shows no signs of malicious content. As with any document from an unfamiliar source, be cautious with links or requests for login details inside it, and keep your PDF reader updated.
Where this verdict could be wrong1 caveat
- The document has been submitted by only two sources and our own static analysis of its contents was not available, so a freshly crafted phishing PDF cannot be fully excluded.
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, including all major antivirus engines that reported.
- Sandbox runs only showed Adobe Acrobat opening the document with its usual helpers.
- No process injection, dropped files or network contacts by the document were recorded.
- Rarely submitted, seen from only two sources.

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.
