MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a document body that explicitly advertises free spins for the game Coin Master, acting as a lure. The primary external URI, http://netcdn.tw/app/406889139/update-coin-master-free-spins-game-hack, likely hosts a malicious payload. The ML classifier also flagged this PDF with high confidence, supporting the suspicious verdict.
