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

The PDF contains multiple embedded URLs that lead to sites offering free game-related content, such as Minecraft generators and Robux. The presence of a 'CLICK HERE TO ACCESS MINECRAFT GENERATOR' text and a heuristic firing for a 'Visual download / call-to-action button lure' suggests a social engineering attempt to trick the user into downloading further content. The ML classifier also flagged this PDF as malicious.
