MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains a prominent link to 'netcdn.tw' which is associated with a lure for 'coin-master-free-link-facebook-game-hack'. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs and a visual download button further supports a malicious intent. The document likely aims to trick users into downloading a secondary payload by presenting a fake offer.
