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

The sample contains a VBA macro that is triggered by the Document_Open event, indicating an attempt to execute code upon opening. The macro attempts to disable virus protection and copy itself to other documents, suggesting a self-propagating or evasive behavior. The ClamAV detection name 'Doc.Trojan.Thus-14' further supports its malicious nature.
