MITRE ATT&CK

T1059.005 Visual Basic 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 initiating malicious actions upon opening. The document body discusses a celebratory event for a TV show, likely a social engineering lure to encourage macro execution. The presence of the Document_Open macro strongly suggests the intent to download and execute a second-stage payload. No specific family could be identified, and no IOCs were directly extracted from the provided evidence.
