MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF was identified as malicious by multiple heuristics, including a critical finding for a link to known malicious redirector infrastructure. The document body, though heavily obfuscated, contains text related to a movie lure, suggesting a phishing or social engineering pretext. The primary IOC is the malicious redirector URL, which is likely used to host or deliver a secondary payload.

  • Image-only document with action trigger (screenshot lure) medium PDF_IMAGE_LURE
    PDF has 1 image(s), only 0 text block(s), carries a click-outward action, and is only 48 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 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.
