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

The PDF file contains a significant number of embedded links, with one heuristic specifically identifying it as a PDF link farm. The primary redirector URL, https://ttraff.cc/pify?keyword=ffxiv+parser+overlay, is flagged as malicious. The document body, though heavily obfuscated, also contains this URL and other links pointing to Shopify domains, suggesting a coordinated effort to distribute content or redirect users. The presence of numerous external links, including a malicious redirector, indicates a likely attempt to lure users to harmful sites or manipulate search engine results.

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.
