MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs and a document body that explicitly advertises free items and hacks for popular games. The ML classifier strongly flagged this PDF as malicious, indicating it likely serves as a lure to download a second-stage payload from the provided URLs. The presence of game-related lures suggests a social engineering tactic to entice users into clicking malicious links.
