MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 User Execution: Malicious File

The PDF file contains a large number of embedded URLs, identified by the PDF_SEO_LINK_FARM heuristic. These links are presented in a way that suggests they are PDF files, but they lead to various domains. The document body contains text related to forex trading, which appears to be a lure to encourage users to click on the links. The primary attack pattern involves tricking users into navigating to external, potentially malicious, websites.

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.
