MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded URLs, identified by the PDF_SEO_LINK_FARM heuristic, which suggests a tactic to manipulate search engine results or redirect users to malicious sites. While no scripts were explicitly extracted, the document body contains text related to forex trading, which may serve as a lure. The embedded URLs are the primary indicators of malicious activity.

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.
