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

The PDF document contains multiple embedded URLs and a visual download button lure, suggesting an attempt to trick the user into downloading a payload. The ML classifier strongly flagged this PDF as malicious, and the presence of URLs related to game hacks and cheats indicates a common social engineering tactic. No scripts were extracted, but the overall structure points to a malicious download attempt.
