MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous links to external resources, with a primary focus on game cheats and hacks for Roblox and Coin Master. The ML classifier strongly flagged this PDF as malicious, and the presence of a download-related heuristic further supports a malicious intent. The primary URL, http://netcdn.co/app/431946152/money-cheats-for-jailbreak-roblox-game-hack, is likely a distribution point for a secondary payload.
