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

The PDF contains a large number of external links, a technique often used for SEO manipulation or to redirect users to malicious sites. The heuristic 'PDF_SEO_LINK_FARM' specifically indicates this behavior, pointing to domains like 'ozhiking.com' and 'prettyelite.org'. While no scripts were extracted, the sheer volume of embedded links suggests a malicious intent to drive traffic to potentially compromised or malicious web pages.
