MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.001 Malicious Link

The PDF file contains a large number of embedded links, including a critical finding of a malicious redirector pointing to 'https://ttraff.com/pify?keyword=captivate+instagram+android'. The document also exhibits characteristics of a PDF SEO link farm, with numerous links to benign Shopify domains, likely to inflate search engine rankings or distribute traffic. The presence of urgency language further suggests a lure to entice users to click on these links.

Heuristics 4

  • 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.
  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
    Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
  • 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.
