T1566.001 Spearphishing Attachment

The PDF document contains numerous URLs and text referencing free Robux, Coin Master spins, and game hacks, indicating a lure for users to download potentially malicious content. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs further supports a suspicious nature. The document's primary goal appears to be tricking users into downloading malware disguised as game cheats or currency generators.
