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

The file is identified as malicious by ClamAV with a signature indicating phishing and trojan activity. It contains an embedded URI pointing to 'bologen.ru', which is likely a phishing lure. The document body, though heavily obfuscated, suggests a search result context related to a Cessna 210 manual, aligning with a phishing pretext.
