MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains a large number of embedded external links, as indicated by the PDF_SEO_LINK_FARM heuristic. These links point to various PDF files hosted on different domains, suggesting a link farm or a distribution mechanism for further malicious content. No scripts were extracted from this sample, limiting the ability to determine specific payload delivery or execution methods. The primary attack pattern observed is the redirection of users to a multitude of external resources.

Heuristics 3

Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

Embedded URL info EMBEDDED_URL
