T1566.001 Spearphishing Attachment

The PDF document contains a lure for "Coin Master Hack Online Without Human Verification" and embeds external URLs pointing to similar cheat/hack download sites. The ML classifier flagged this PDF as malicious, and the presence of embedded URLs suggests an attempt to redirect users to download potentially unwanted or malicious software. No scripts were extracted, but the overall pattern indicates a social engineering lure for software downloads.
