MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and text that explicitly promise free in-game currency for popular games, acting as a lure. The primary external URI, http://netcdn.tw/app/431946152/get-robux-game-hack, likely hosts a malicious payload. The ML classifier strongly flagged this PDF as malicious, supporting the suspicious nature of the content.
