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

The PDF file contains a significant number of external links, a common tactic for SEO poisoning and distributing malicious content. The heuristic 'PDF_SEO_LINK_FARM' indicates a mass of external PDF links, with 'issakasoccerfootball.com' being a dominant host. The document body, though heavily obfuscated, contains a URL that matches one of the extracted external links, suggesting a lure to a potentially malicious website. No scripts were extracted from this sample.

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.
