MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic. These links point to a domain that appears to be used for hosting numerous PDF documents with numeric slugs, suggesting a link farm or SEO poisoning tactic. While the document body is heavily obfuscated, the presence of these links indicates an attempt to drive traffic to external resources, likely for malicious purposes such as distributing further malware or phishing content.

  • 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.
