MITRE ATT&CK
T1559.002 Component Object Model Hijacking T1204.002 Malicious File

The PDF contains embedded RichMedia (Flash) content, identified as 'sploit.swf', which is a strong indicator of an exploit attempt. The presence of JavaScript actions and embedded JS streams further supports the likelihood of malicious code execution. The primary attack vector appears to be leveraging a Flash vulnerability within the PDF document.

Heuristics 5

  • RichMedia (Flash) high PDF_RICHMEDIA
    PDF contains /RichMedia (Adobe Flash) which is a historic exploit vector
  • JavaScript action low 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.
  • Embedded file low PDF_EMBEDDED
    PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
  • 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.
