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

The document contains a lure instructing the user to copy and paste content into a command-line context, which is a common technique for executing malicious scripts or downloading further payloads. The presence of multiple URLs suggests an attempt to redirect the user to malicious sites. While no scripts were directly extracted, the ML classifier and heuristic firings strongly indicate malicious intent.
