MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a document body that explicitly advertises "Coin Master Hack 2021" and various Roblox-related cheats and freebies. The primary malicious URL identified is http://netcdn.co/app/406889139/coin-master-hack-2021-ios-download-game-hack, which likely serves as a download link for a secondary payload. The ML classifier strongly flagged this PDF as malicious, supporting the conclusion that it is designed for social engineering and malware distribution.
