T1105 Ingress Tool Transfer
The sample is a malicious Office document containing a VBA macro that is automatically executed upon opening (Document_Open). The macro utilizes CreateObject to execute obfuscated code, which is a common technique for Emotet. The ClamAV detection also strongly suggests Emotet. The script's primary function appears to be downloading and executing a secondary payload, indicated by the obfuscated code and the embedded URL, which is characteristic of Emotet's infection chain.
