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

The PDF document contains a deceptive title related to Cisco mobility express and embeds a large number of external links. These links point to various domains, many of which appear to be part of a link farm designed to host malicious content or redirect users to phishing sites. The heuristic 'PDF_SEO_LINK_FARM' strongly indicates this malicious intent, suggesting the document is used for SEO poisoning or to distribute malware via numerous disguised URLs.

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.
