MITRE ATT&CK
T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The PDF file is identified as malicious by multiple heuristics, including a critical finding for a malicious redirector link. The document's structure suggests it's an image-based lure, typical of phishing attacks designed to trick users into clicking embedded links. The embedded URL leads to a known malicious redirector, likely serving as a gateway to further malicious content or exploits.

  • 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 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.
  • 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.
