MITRE ATT&CK
T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The ML classifier strongly indicated maliciousness, and the document body contains numerous URLs promoting free in-game items for popular games. The primary external URI, http://netcdn.tw/app/479516143/how-to-get-minecraft-for-free-ios-game-hack, likely leads to a payload or phishing page. The presence of a download button lure further supports a malicious workflow aimed at tricking users into downloading further malware or providing sensitive information.
