MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains a significant number of external links, identified by the PDF_SEO_LINK_FARM heuristic. The document body, though partially corrupted, contains a URL that points to a list of anti-inflammatory drugs, suggesting a lure to a potentially malicious website. The primary function appears to be directing users to a large farm of external PDF files hosted on various domains, likely for SEO manipulation or to distribute further malicious content.

Heuristics 3

Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

Embedded URL info EMBEDDED_URL
