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

The ML classifier strongly indicated maliciousness, and the document body contains numerous links related to game hacks and free currency, such as Robux. The presence of an external URI pointing to 'netcdn.co' further suggests a malicious download or redirection attempt. No scripts were extracted from this sample.
