MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous links to external websites, including one at 'http://netcdn.co/app/431946152/get-roblox-synapsex-free-game-hack', which likely serves as a lure for downloading malware. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs and a visual download button further supports a malicious intent to trick users into downloading unwanted software. No scripts were extracted from this sample.
