MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 User Execution: Malicious File

The PDF document contains embedded URLs and a document body that promotes downloading an application related to game hacks and free spins. The presence of a 'download button' heuristic and the ML classifier's high confidence score indicate a malicious intent to trick the user into executing a payload. The primary URL http://netcdn.tw/app/406889139/free-spin-coin-master-twitter-game-hack is highly suspicious.
