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

The PDF document contains numerous embedded URLs, with a primary focus on game-related cheats and hacks, suggesting a lure for users to download potentially malicious content. The ML classifier strongly flagged this PDF as malicious, reinforcing the suspicious nature of the embedded links. The presence of a 'download button' heuristic further supports the attack pattern of enticing users to click on malicious links.
