MITRE ATT&CK

T1059.005 Visual Basic for Applications T1204.002 Malicious File

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 presents a legal-sounding agreement, likely a lure to trick the user into enabling macros. The presence of VBA macros and the Document_Open heuristic strongly suggest the intent is to execute malicious code upon opening the document, potentially to download a second-stage payload.
