MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous links to external websites, many of which are hosted on domains related to game "hacks" and cheats. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests an attempt to redirect the user to a malicious download or exploit site. While no scripts were explicitly extracted, the overall structure and content point towards a phishing or malware distribution attempt.
