MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous links to external resources, with a primary URL pointing to a file hosted on netcdn.tw. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs suggests an attempt to redirect the user to download potentially harmful content. The document body's content, advertising game cheats, supports the lure-based attack pattern.
