Why we think so
2 points against it and 4 in its favour, checked against the scan evidence.
The reasoning behind this verdict
None of the 62 antivirus engines that checked it flagged this PDF document. When it was opened in the sandbox, only Adobe Acrobat and its helper processes ran, with no injection into other programs and no network activity of its own. It is rare and recently seen, so stay alert for links asking you to log in.
None of the 62 antivirus engines that checked it flagged the file, including 17 major antivirus engines that returned a clean result. The sandbox runs show the document opened in Adobe Acrobat with only Adobe's own crash and logging helpers starting. Two technique labels appeared in the summary, but nothing they describe was actually recorded, which is common for documents opened in a viewer. The only network contact was the analysis machine's own background traffic. The file is rare and recently observed, and its theme resembles common business lures, so any links inside deserve caution.
What We Detected
None of the 62 antivirus engines that checked it flagged this PDF document, and 17 major antivirus engines reported it clean. No engine named any malware family.
Threat Behavior
In the sandbox runs the document was opened in Adobe Acrobat, and only Adobe's own components (the browser renderer, crash processor and log transport) started. No other process was injected into, no persistence was set up, and the only network contact was the analysis machine's own background traffic. Technique labels for process injection and credential access appeared in the summary without any matching activity, which is typical for documents opened in a viewer.
What To Do Now
The file itself shows no harmful content. Because it is rare and quotation-themed, treat any links or login prompts inside it with caution and confirm the sender before entering credentials.
Where this verdict could be wrong1 caveat
- The document is rare and recently observed, with a single submitter, and request-for-quotation themed PDFs are a common phishing lure; a phishing link inside the document would not necessarily be flagged by the engines.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

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.
