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

This PDF document contains a large number of external links, identified by the PDF_SEO_LINK_FARM heuristic. The primary URL http://iphonebuyerz.com/uploads/1/3/0/6/130621422/130621422.html#patch+fr+batman+telltale and numerous others suggest a link farm or redirection scheme. The document body is heavily obfuscated and contains embedded URLs, reinforcing the malicious intent of directing users to external sites.

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.
