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

The PDF contains numerous links to external websites, many of which are related to game cheats and hacks for popular games like Coin Master and Roblox. The ML classifier flagged this PDF as malicious with high confidence. The presence of a 'download button' heuristic further supports the lure of downloading content. The document body, though partially corrupted, also contains a URL pointing to game-related cheats.
