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

The PDF file contains a large number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic. These links likely serve as a link farm to redirect users to malicious websites, consistent with phishing or malware distribution campaigns. The ClamAV detection further supports its malicious nature. No scripts were extracted from this sample.

Heuristics 3
