MITRE ATT&CK
T1059.005 Visual Basic
T1566.001 Spearphishing Attachment
T1203 Exploitation for Client Execution
The sample is a malicious OLE document containing VBA macros, specifically a Document_Open macro that uses CreateObject to execute code. This indicates an attempt to download and run a second-stage payload. The ClamAV detection as 'Doc.Downloader.Generic' further supports this. The obfuscated VBA code and the presence of a Document_Open macro strongly suggest a downloader functionality.
