T1566.001 Spearphishing Attachment T1204.002 Malicious File

The PDF document contains an embedded URI pointing to a Minecraft hack client download, and the ML classifier strongly flagged it as malicious. The document body also includes a call-to-action phrase, suggesting a lure to download potentially malicious software. The presence of numerous related PDF links further supports a campaign distributing such lures.
