MITRE ATT&CK
T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The PDF contains embedded URLs and a visual download button lure, suggesting an attempt to trick the user into downloading a secondary payload. The ML classifier strongly flagged this PDF as malicious, and the presence of game-related lures like 'Roblox Vehicle Simulator Hack' and 'Coin Master Free Spins' indicates a social engineering tactic. The primary IOC is the external URI pointing to a potential download site.
