T1566.002 Spearphishing Attachment
The PDF contains a large number of embedded links, forming a link farm. The ML classifier also flagged this PDF as malicious. The primary attack pattern appears to be SEO poisoning, directing users to a large collection of external PDF documents hosted on the domain 'cefasfese.4pu.com'. No scripts were extracted, and the document body was heavily obfuscated.
