MITRE ATT&CK

The sample is a Microsoft Word document containing VBA macros, specifically a Document_Open macro. The document body presents a school supply list, likely as a lure to trick the user into enabling macros. The presence of VBA macros and the Document_Open auto-execution trigger are strong indicators of malicious intent, commonly used for initial access or payload delivery.
