MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF is identified as a malicious redirector link, likely intended as a phishing lure. The document body contains a URL that redirects to a known malicious infrastructure. The ML classifier also strongly indicates maliciousness. The PDF structure and heuristics suggest it's designed to trick users into clicking the embedded link, which is a common tactic for credential harvesting or malware delivery.

Heuristics 3

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK
    PDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
  • 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 9 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.
