MITRE ATT&CK

T1059.005 Visual Basic

The file is a Microsoft Word document containing VBA macros, specifically a Document_Open macro. ClamAV detections indicate it is a Trojan. The presence of a Document_Open macro suggests an attempt to automatically execute malicious code when the document is opened, likely to download and execute a secondary payload. The extracted artifact name 'macros.bas' and the ClamAV detection 'Doc.Trojan.Sxe-1' further support this assessment.
