MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF contains a large number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic. These links are disguised as book titles and point to a single domain, suggesting a link farm or redirection scheme. The ML_NYX_PDF_MALICIOUS heuristic also flagged the document with high confidence. The embedded URLs are the primary IOCs, and the attack pattern involves luring users to click these links, likely to download further malicious content or redirect to phishing sites.

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

  • 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.
