MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF file contains embedded JavaScript and an embedded script payload, indicating malicious intent. The 'PDF_IMAGE_LURE' heuristic suggests the document is designed as a phishing lure, presenting an image to trick the user into clicking an embedded action. No document body text was available for analysis, but the presence of embedded scripts and the lure technique strongly suggest the document is intended to redirect the user to a malicious site or download further malware.

Heuristics 7

  • Embedded script payload in PDF stream medium PDF_EMBEDDED_SCRIPT_PAYLOAD
    PDF stream bytes contain an HTML/XFA <script> tag without accompanying Windows shell-execution primitives — common in accessible XFA forms but worth surfacing for analyst review.
  • Image-only document with action trigger (screenshot lure) medium PDF_IMAGE_LURE
    PDF has 2 image(s), only 1 text block(s), carries a click-outward action, and is only 269 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
  • Embedded file low PDF_EMBEDDED
    PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
  • 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. (matched inside decoded stream)
  • 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. (matched inside decoded stream)
  • XFA form low PDF_XFA
    PDF uses XML Forms Architecture — can contain script logic (matched inside decoded stream)
  • 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.
