MITRE ATT&CK

T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The file is a Microsoft Word document containing VBA macros, specifically triggering a Document_Open macro. This indicates an attempt to automatically execute malicious code when the document is opened. The ClamAV detection as 'Doc.Trojan.Thus-8' further confirms its malicious nature. The primary attack vector is likely social engineering to entice the user to open the malicious document, leading to macro execution.
