MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains a heuristic firing for a 'PDF_SEO_LINK_FARM', indicating a large number of embedded external links. The document body is filled with text related to 'Forex trading zimbabwe' and other trading terms, likely as a lure to disguise the malicious intent. The embedded URLs are likely used to redirect users to potentially malicious websites or for SEO manipulation purposes.

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.
