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

The PDF file contains a lure related to a "Panasonic smart tv owners manual" and embeds multiple links. One critical heuristic indicates that the PDF links to known malicious redirector infrastructure, specifically the URL https://ttraff.me/wix?keyword=panasonic+smart+tv+owners+manual. Another heuristic identifies a PDF link farm, with the first URL being https://cdn.shopify.com/s/files/1/0436/5654/4409/files/darkness_rises_pc.pdf. The presence of these links and the redirector strongly suggests a phishing or social engineering attack.

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.
