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

The PDF document contains numerous embedded URLs, with a primary focus on 'hacks-for-roblox-sript-reader-game-hack'. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs and a visual download button heuristic further supports a malicious intent. The document's content and structure suggest it is designed to trick users into downloading potentially harmful software by posing as a game hack.
