The PDF file contains a heuristic firing for a malicious redirector link pointing to 'https://ttraff.cc/pify?keyword=antimatter+dimensions+infinity+challenge+5+guide'. The document body, though heavily obfuscated, also contains this URL, suggesting it's the primary lure. The heuristic 'SE_URGENCY_LURE' further supports the idea that the document is designed to trick the user into clicking the link. No scripts were extracted from this sample.

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.
  • Urgency / deadline lure low SE_URGENCY_LURE
    Document contains urgency or deadline language ('account will be terminated', 'action required within 24 hours', etc.) — useful context, but low-signal without other findings
  • 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.
