MITRE ATT&CK
T1059.001 PowerShell

The PDF file was flagged by an ML classifier with high confidence, indicating malicious intent. Heuristics indicate the presence of embedded JavaScript, a common technique for delivering malicious payloads. The JavaScript's exact function is not fully discernible due to potential obfuscation, but its presence strongly suggests an attempt to execute further malicious code. No specific malware family could be identified.

Heuristics 4

  • JavaScript action low 1 related finding PDF_JAVASCRIPT
    PDF contains a /JavaScript action. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
  • Embedded JS stream low PDF_JS
    PDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
  • Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTAL
    The same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
