T1566.001 Spearphishing Attachment

The PDF contains multiple embedded URLs and a prominent external URI pointing to a domain associated with game hacks and cheats, specifically 'a-lot-of-robux-game-hack'. The ML classifier strongly flagged this PDF as malicious. The presence of these links suggests the document is designed to trick users into downloading further malicious content, likely a second-stage payload.
