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

The PDF document contains numerous links to external websites, many of which are related to game hacks and cheats for popular titles like Coin Master and Roblox. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs and a visual download button lure suggests an attempt to trick the user into downloading a second-stage payload. The document body itself contains references to these lures and the primary malicious URL.
