MITRE ATT&CK
T1059.005 Visual Basic for Applications T1204.002 Malicious File

The file is an OLE document containing VBA macros, specifically a Document_Open macro, which is a common technique for initial execution. The document body presents a plausible lure about a celebrity, designed to encourage the user to enable macros. While no specific malicious script content or network indicators were extracted, the presence of the Document_Open macro and the ClamAV detection strongly suggest malicious intent, likely to download and execute a second-stage payload.
