MITRE ATT&CK
T1059.001 JavaScript/JScript T1566.002 Spearphishing Attachment

The PDF file contains embedded JavaScript and is flagged as malicious by an ML classifier. The heuristics indicate it's an image-only document designed as a lure, with a clickable action that triggers an external URI. The embedded JavaScript likely executes this action, redirecting the user to the provided malicious URL, which is typical for phishing or malware distribution.

    PDF has 1 image(s), only 0 text block(s), carries a click-outward action, and is only 52 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
  • 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. (matched inside decoded stream)
  • External URI info PDF_URI
    PDF contains an external URL action
  • 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.
