MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF contains embedded URLs and a document body that advertises cheats and free spins for the game Coin Master, strongly suggesting a lure for users to download malicious content. The ML classifier also flagged this PDF with high confidence. While no scripts were directly extracted, the presence of embedded URLs and the nature of the lure indicate a likely attempt to trick users into downloading a second-stage payload.
