MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV with a phishing and trojan detection. It contains embedded URLs, one of which is flagged as confirmed benign, but others are unknown and potentially malicious. The document body is heavily obfuscated, preventing a clear understanding of its specific lure, but the presence of multiple embedded URLs suggests an attempt to redirect the user to external sites. No scripts were extracted from this sample.
