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

The ML classifier strongly indicated maliciousness, and the document contains a prominent external URI pointing to a suspicious URL. Additionally, a heuristic detected a visual download button lure, suggesting an attempt to trick the user into downloading a payload. The presence of numerous other URLs further supports a malicious intent to redirect the user to potentially harmful content.
