PDF with embedded JS and sandbox-detected offensive techniques but zero AV detections.
No antivirus engine flagged the file, yet sandbox behaviour shows process injection, credential-dumping and direct-IP traffic. Two YARA rules also matched. Host reputation data is missing, leaving the risk unresolved.

Before opening
Do not open it until the source can be verified independently.
If you already opened it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Get a fresh copy from the original trusted source and verify its exact hash when possible.
Intelligence
The saved assessment, checked against the scan evidence and recorded coverage.
The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
No antivirus engine flagged the file, yet sandbox behaviour shows process injection, credential-dumping and direct-IP traffic. Two YARA rules also matched. Host reputation data is missing, leaving the risk unresolved.
Zero detections across 76 engines, including 18 tier-1, is a strong clean signal. However, the single sandbox run recorded ten offensive MITRE techniques and direct-IP connections whose reputation could not be checked. Two community YARA rules fired, and the file is three years old with only medium prevalence. These conflicting signals place the sample in mixed-signals territory.
What We Detected
76 engines scanned the PDF; none returned a malicious or suspicious result. Sandbox execution recorded MITRE techniques T1055 (process injection), T1003 (credential dumping), T1486 (data encrypted for impact) and direct-IP traffic to eight addresses. Two YARA rules (adonunix2, vmdetect) matched, indicating anti-analysis behaviour.
Threat Behavior
The PDF contains embedded JavaScript and performed actions typical of malicious documents, yet no engine labelled it malicious. Contacted-host reputation data is unavailable, so the nature of the external IPs remains unknown.
What To Do Now
Do not open the file. Re-scan with updated engines and, if possible, obtain a host-reputation check on the observed IPs before trusting the document.
Where this verdict could be wrong1 caveat
- YARAify returned 2 rules, but rule names (adonunix2, vmdetect) describe generic anti-analysis rather than a named malware family.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/76 engines flagged the file
- 18 tier-1 engines reported clean
- No dropped malicious children
- No brand-mismatch or adversarial filename
- Sandbox recorded 10 offensive MITRE techniques
- Direct-IP traffic with no domain names
- Two YARA rules matched (adonunix2, vmdetect)
- contactedHosts reputation check incomplete
Treat the document as untrusted until a complete host-reputation check and updated multi-engine scan are available.

What this file does
Observed actions and their security significance
High concern: Accessed operating-system credential data, which can expose saved passwords.
High concern: Injected code into another process, a technique that can conceal execution.
High concern: Encrypted files or data, behaviour commonly associated with ransomware.
High concern: Searched files or settings where passwords and keys may be stored.
High concern: Accessed browser or password-store data that may contain saved logins.
High concern: Attempted to impair or bypass security controls.
Moderate concern: Removed execution artefacts or logs, which can conceal activity.
These are observed capabilities from an isolated analysis. A technique does not prove malicious intent on its own, and the file never ran on your device.

Signatures and behavior heuristics
A community signature or high-severity behavioral heuristic matched. Signatures identify known patterns; heuristics are strong leads but are not proof on their own.
- adonunix2
- vmdetect
The saved runtime evidence maps this activity to MITRE T1055 (Process Injection). The mapping supports possible process injection, but it does not prove the exact injection method or the operator's intent.
Evidence"C:\Program Files\Adobe\Acrobat DC\Acrobat\Acrobat.exe" "C:\Users\<USER>\AppData\Local\Temp\readme.pdf"MITRE T1003 (OS Credential Dumping) mapped by at least one sandbox run.
The sample contacted an external IP address directly and no application domain was recorded. Direct-IP traffic also occurs in legitimate installers and infrastructure, so this is supporting context only and requires corroboration from host reputation and other runtime evidence.
