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

The PDF document contains multiple embedded URLs, with one prominent URL pointing to a site offering a 'roblox-hack-me-game-hack'. The ML classifier strongly flagged this PDF as malicious, and the presence of download-related lures further supports a malicious intent. The document likely serves as a lure to trick users into downloading malware disguised as game cheats or hacks.
