MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV and an ML classifier, with heuristics indicating the presence of external URIs. Although the document body is heavily obfuscated, the presence of embedded URLs suggests an attempt to redirect the user to malicious content. The primary attack vector appears to be a phishing lure, likely leading to the download of further malicious content.
