MITRE ATT&CK

T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The file contains VBA macros, specifically a Document_Open macro, which is a common technique for executing malicious code upon opening the document. The ClamAV detection 'Doc.Trojan.Thus-8' further confirms its malicious nature. The document body, while appearing benign, is likely a lure to encourage macro execution. The primary attack vector is the execution of embedded VBA macros.
