MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of external links, identified as a 'PDF SEO LINK FARM' heuristic. The document body, though heavily obfuscated, contains references to URLs such as 'http://maeganprovan.com/uploads/1/3/0/7/130740128/130740128.html#the+shock+doctrine+full+documentary' and 'http://rosebudtel.info/uploads/1/3/0/7/130776452/57d18bb9b6de.pdf'. This suggests the primary purpose is to redirect users to a multitude of other sites, potentially for SEO manipulation or to host further malicious content.

Heuristics 3

  • 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.
  • External URI info PDF_URI
    PDF contains an external URL action
  • 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.
