MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains numerous links to external websites, including one directly hosted on 'netcdn.co', which likely serve as download sites for malware or unwanted software. The document body and extracted URLs suggest a lure for game-related cheats or currency, a common tactic for distributing malware. No scripts were extracted from this sample, but the presence of external URIs and the ML classifier's high confidence indicate a malicious intent to redirect the user to a malicious resource.
