T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs and a prominent call-to-action to download a "Roblox Generator". The ML classifier strongly flagged this PDF as malicious, and the presence of external links suggests an attempt to redirect the user to a malicious site or download a secondary payload. The document body text and extracted URLs indicate a lure related to game hacking or cheats.
