MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.002 Malicious File

The PDF contains a large number of external links, identified by the PDF_SEO_LINK_FARM heuristic, pointing to other PDFs. This is a common technique for distributing phishing content or redirecting users to malware download sites. The ClamAV detection further confirms its malicious nature. The embedded URLs are the primary indicators of compromise, suggesting a link farm used for SEO poisoning or traffic redirection.
