MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF file contains a large number of embedded links, identified by the PDF_SEO_LINK_FARM heuristic, pointing to external PDF documents. While the ML classifier also flagged this as malicious, the primary attack pattern observed is the distribution of links rather than direct payload delivery. The document body, though heavily obfuscated, contains these URLs, suggesting a lure to a link farm. No scripts were extracted from this sample.

Heuristics 2

  • 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.
