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

The file was detected as a phishing trojan by ClamAV. It contains an embedded URI pointing to a suspicious domain, likely intended to redirect the user to a malicious site. The document body, though heavily obfuscated, suggests a lure related to 'idle clicker business farming games'. No scripts were extracted, but the presence of embedded URIs and the ClamAV detection strongly indicate a malicious intent to redirect users.
