Verdict Safe
Is this PDF document safe? Yes, no threats found.
No antivirus engine detected the PDF, and its clean sandbox run provides no concrete support for the isolated credential-access and injection mappings.
Read the whole reasonShow less
Moderate evidence · No engine flags it, but no publisher signature confirms who made it.
The file can be handled with standard document precautions. Use an updated, sandboxed PDF reader, keep protection enabled, and avoid interacting with unexpected active content.

Chapter 02
Why we think so
2 points against it and 5 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, including the reporting major antivirus engines. One sandbox run completed without a malicious verdict; although it mapped credential-dumping and process-injection techniques, it identified no injection target or other concrete corroboration.
The strongest evidence is the complete absence of detections among 74 engines, including no major detection. A completed sandbox run produced a clean verdict and showed the document opening through Adobe Acrobat alongside related Adobe and Windows Installer processes. The and mappings are cautionary, but no injected process, credential target, malicious child, or malicious sandbox verdict supports them. The only sample-attributed domain was fully covered by the host-reputation check and had no malicious or suspicious cache result; the DNS address was identified as sandbox background traffic. The document's AcroForm and automatic-action features warrant normal PDF precautions but do not outweigh the broader evidence.
What We Detected
No malware family was identified, and malware-specific external rules produced no match.
Threat Behavior
One completed sandbox run opened the document with Adobe Acrobat and returned a clean verdict. It mapped T1055 process injection and T1003 credential dumping, but no injected target process or concrete credential-access operation was recorded. The sample-attributed Adobe domain was fully covered by the available host-reputation check without a malicious or suspicious result, while the DNS address was marked as analysis-environment background traffic. Ten generated files lack individual saved verdicts, so they provide no positive or negative conclusion by themselves.
What To Do Now
Open the document only in an updated PDF reader, preferably with protected mode enabled. Keep security software active, and avoid enabling embedded actions or following unexpected links if the document came from an untrusted source.
Where this verdict could be wrong3 caveats
- The PDF carries AcroForm and automatic-action features, which can increase document attack surface even though no engine detected a payload.
- One sandbox mapped process injection and credential dumping, but it supplied no target process or corroborating malicious verdict.
- Ten generated files have no saved child verdict, so their individual reputation remains unconfirmed.
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 62 antivirus engines that checked it flagged the file.
- The completed sandbox run did not issue a malicious verdict.
- No injected process, persistence indicator, or confirmed malicious child was recorded.
- The fully covered sample-attributed domain had no malicious or suspicious cache result.
- No malware-specific external rule matched the file.
- The PDF contains an AcroForm and an automatic-action feature, expanding the document's potential active-content surface.
- Ten generated files do not have individual saved 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.
