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

The PDF file contains a significant number of embedded links, with the primary heuristic identifying it as a PDF SEO link farm. One of the embedded URLs, 'https://ttraff.cc/wix?keyword=iglesia+cristiana+de+tlaxiaco+videos', is flagged as a known malicious redirector. The document body also contains this URL, suggesting a deliberate attempt to redirect users to potentially harmful content. The presence of numerous links, including one to a malicious redirector, indicates a likely attack pattern focused on traffic redirection or SEO manipulation.

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.
