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

This PDF document contains a mass of external links, many of which point to Shopify domains, but one critical link redirects to `https://ttraff.com/pify?keyword=2020+telugu+festival+calendar+pdf`. This indicates a link farm or redirection tactic designed to obscure the ultimate destination. The document body itself is heavily obfuscated and contains embedded URLs, further supporting the malicious redirection pattern.

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.
  • 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.
  • 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.
