MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV with a specific signature indicating it is a phishing trojan. It contains an embedded URI that, while flagged as benign by reputation services, is likely part of a phishing lure. The document body is heavily obfuscated and does not provide clear textual content, but the presence of the URI and the ClamAV detection strongly suggest a phishing attempt.
