MITRE ATT&CK
T1059.005 Visual Basic

The file contains VBA macros, including AutoOpen and Auto_Close, which are commonly used to execute malicious code upon opening or closing a document. ClamAV detections indicate this is a known trojan. The document body, while appearing to be biographical information about Jim Morrison, is likely a lure to encourage macro execution.
