MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains a large number of external links, identified by the PDF_SEO_LINK_FARM heuristic. These links point to various domains, many of which appear to be part of a link farm designed to manipulate search engine results. The embedded document body text also contains one of these URLs, suggesting a direct attempt to redirect the user. The primary goal appears to be SEO manipulation or directing users to potentially malicious content hosted on these numerous domains.

  • Embedded URL info EMBEDDED_URL
