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

The PDF document was identified as malicious due to the presence of numerous embedded links. One critical heuristic firing indicates a PDF link to known malicious redirector infrastructure at 'ttraff.com'. Another critical heuristic points to a PDF link farm, with the first URL being 'cdn.shopify.com/s/files/1/0431/9186/1412/files/66670925821.pdf'. The document body contains garbled text but also includes the 'ttraff.com' URL, suggesting a potential lure or redirection mechanism.

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.
