MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous links to external resources, including a primary URL hosted on 'netcdn.tw' that advertises a 'Coin Master Hack'. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs and a call-to-action button further supports a malicious intent. The document likely serves as a lure to download a second-stage payload or exploit.
