The file is identified as malicious by ClamAV with the signature 'Doc.Trojan.Panther-2'. Static analysis detected a high-severity 'OLE_VBA_DOCOPEN' heuristic, indicating the presence of a Document_Open macro. This macro is likely responsible for executing malicious actions, such as downloading and running a second-stage payload, as is common with this type of malware. No specific family could be confidently identified.
