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

The PDF document contains numerous embedded URLs, including one pointing to 'netcdn.co', which likely serves as a download lure for game cheats or hacks. The ML classifier strongly flagged this PDF as malicious, and the presence of multiple game-related URLs suggests a social engineering attempt to trick users into downloading further malware. No scripts were extracted from this sample.
