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

The PDF document contains multiple embedded URLs, with a primary focus on luring users to download game-related content such as Roblox hacks and free Robux. The ML classifier strongly flagged this PDF as malicious, and the presence of a download-themed button heuristic further supports a malicious intent. The primary IOC is the URL http://netcdn.tw/app/431946152/roblox-studio-free-templates-game-hack, which is likely a distribution point for a secondary payload.
