T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a visual download lure, suggesting an attempt to trick the user into downloading a malicious application disguised as a game hack. The ML classifier strongly flagged this PDF as malicious, and the presence of multiple external URLs reinforces the suspicious nature of the file. No scripts were extracted, but the overall pattern indicates a downloader or dropper.
