MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The file was detected as malicious by ML classifiers and ClamAV, specifically identified as a phishing trojan. The document body, though heavily obfuscated, contains text related to a movie lure, and an embedded URI points to a URL that appears to be part of a phishing or malware distribution scheme. No scripts were extracted, but the presence of external URIs suggests an attempt to redirect the user to a malicious site.
