MITRE ATT&CK

T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The file is a Microsoft Word document with a high-severity heuristic indicating the presence of VBA macros. The 'Document_Open' macro firing suggests that the malicious code executes automatically upon opening the document. ClamAV detection as 'Doc.Trojan.Panther-2' further confirms its malicious nature. The primary attack pattern involves leveraging VBA macros to initiate a malicious process, likely a downloader for further stages.
