MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF contains a critical heuristic firing indicating it links to known malicious redirector infrastructure. The embedded URL, 'https://ttraff.club/pify?keyword=diamond+dimensions+modpack+list', is the primary indicator of malicious intent. While no scripts were explicitly extracted, the PDF structure and the presence of embedded URLs suggest an attempt to lure the user to a malicious site, likely for phishing or further payload delivery.

Heuristics 2

  • 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.
  • 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.
