MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a significant 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. The primary purpose seems to be SEO manipulation or redirecting users to potentially malicious content hosted on these numerous domains. No scripts were extracted from this sample.
