MITRE ATT&CK
T1059.001 PowerShell
The presence of a critical ClamAV detection and high-severity heuristics for VBA macros and PowerShell execution strongly indicate malicious intent. The Auto_Close macro and VBA p-code auto-execution suggest an attempt to run code upon opening or closing the document. The embedded URL, though marked as benign, is included as a potential IOC. The primary attack pattern involves leveraging VBA to initiate PowerShell, a common technique for downloading and executing further malicious content.
