MITRE ATT&CK

T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The sample is a malicious Word document containing VBA macros, specifically a Document_Open macro. This macro is designed to execute automatically when the document is opened, likely to download and execute a secondary payload. The ClamAV detection 'Doc.Trojan.Thus-8' further confirms its malicious nature. The document body discusses historical events, likely a lure to encourage macro execution.
