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

The PDF document contains numerous links to external websites, many of which are hosted on 'atrax.hr' and 'netcdn.tw', and are disguised as guides for obtaining free spins or hacks for popular games. The ML classifier strongly flagged this PDF as malicious, and the presence of these deceptive links suggests a social engineering attempt to trick users into visiting potentially harmful sites. No scripts were extracted from this sample.
