MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs, with a primary external URI pointing to 'http://netcdn.tw/app/406889139/www-coin-master-game-hack'. The document body and heuristics suggest a lure related to game cheats and virtual currency, aiming to trick users into downloading further content. No scripts were extracted, but the presence of external links and the ML classifier's high confidence indicate a malicious intent.
