MITRE ATT&CK

T1059.005 Visual Basic for Applications T1566.001 Spearphishing Attachment

The file is a Microsoft Word document containing VBA macros, specifically a Document_Open macro, which is a common technique for initial execution. The document body appears to be a curriculum vitae, suggesting a social engineering lure. The presence of VBA macros and the Document_Open heuristic strongly indicate that the file is designed to execute malicious code upon opening. The ClamAV detection as 'Doc.Trojan.Thus-8' further confirms its malicious nature.
