T1059.005 Visual Basic
T1059.001 PowerShell
T1204.002 Malicious File
The sample is a malicious DOC file containing a large VBA macro, indicated by the OLE_VBA_MACROS heuristic. The presence of an AutoOpen macro and a GetObject call (OLE_VBA_AUTOOPEN, OLE_VBA_GETOBJ, OLE_VBA_PCODE_AUTOEXEC_EXEC) strongly suggests that the macro is intended to execute code upon opening the document. The ClamAV detection further confirms its malicious nature. The macro's likely purpose is to download and execute a second-stage payload, although the specific payload and download mechanism are not detailed in the provided evidence.
