T1566.001 Spearphishing Attachment
This PDF document contains a large number of external links, many of which are structured as a link farm for SEO purposes, pointing to other PDF files. The document body and embedded links suggest a lure for game hacks and cheats, likely intended to lead users to malicious websites or download further malware. The ML classifier strongly indicated maliciousness, and the PDF structure with numerous external links supports this assessment.
