MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous links to external websites, including one at http://netcdn.tw/app/406889139/master-coin-hack-app-game-hack, which is likely a lure for downloading a malicious application. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs and a visual download button heuristic further supports a malicious intent. No scripts were extracted from this sample.
