MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of external links, a technique often used for SEO manipulation or to distribute further malicious content. The heuristic 'PDF_SEO_LINK_FARM' specifically identifies this behavior, indicating a malicious intent to redirect users to potentially harmful sites. No scripts were extracted, and the document body is heavily obfuscated, but the presence of numerous external URLs is a strong indicator of malicious activity.
