MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs, with the primary one being http://netcdn.tw/app/406889139/coin-master-free-spin-generator-without-human-verification-game-hack. The document body and heuristics suggest a lure for game hacks or cheats, likely leading to a download of a second-stage payload. The ML classifier strongly flagged this PDF as malicious.
