MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains multiple embedded URLs, with a primary one pointing to a 'coin-master-hack-no-survey-2021-game-hack'. The ML classifier strongly flagged this PDF as malicious, and the presence of download-related lures reinforces a social engineering attack. The document's content and embedded links suggest it is designed to trick users into downloading potentially malicious files disguised as game cheats or hacks.
