MITRE ATT&CK
T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The file is an OLE document containing VBA macros, specifically a Document_Open macro, which is a common technique for initial execution. ClamAV detected this file as 'Doc.Trojan.Thus-8', indicating a known malicious pattern. The presence of the Document_Open macro suggests the intent is to automatically execute malicious code upon opening the document, likely to download and execute a second-stage payload.
