MITRE ATT&CK

T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The file is a Microsoft Word document containing a VBA macro, specifically a Document_Open macro, which is a common technique for initial execution. ClamAV detections (Doc.Trojan.Flop-2 and Doc.Trojan.Flop-1) indicate a known malicious pattern. The presence of the Document_Open macro suggests the intent is to automatically run malicious code when the document is opened, likely to download and execute a second-stage payload.
