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

The PDF document contains numerous embedded URLs, with a primary focus on game hacks and cheats for platforms like Roblox and Coin Master. The ML classifier strongly flagged this PDF as malicious, and the presence of a download-related heuristic further supports the intent to trick users into downloading a secondary payload. The primary IOC is the URL http://netcdn.tw/app/431946152/roblox-gang-game-hack, which is directly referenced in the document.
