The PDF contains a link to a known malicious redirector, ttraff.com, disguised as a document about English-Marathi word substitution. The PDF also acts as a link farm, pointing to numerous other PDFs hosted on Shopify. The embedded URL in the document body, 'https://ttraff.com/pify?keyword=one+word+substitution+in+english+with+marathi+meaning+pdf', is the primary indicator of malicious intent, likely leading to further malicious content or phishing pages.

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.
