MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs, including one pointing to 'netcdn.tw' which is associated with game cheats and hacks. The ML classifier strongly flagged this PDF as malicious, and the presence of a visual download button heuristic further supports a malicious intent to trick the user into downloading a payload. No scripts were extracted from this sample.
