MITRE ATT&CK

T1059.001 PowerShell

The presence of VBA macros, specifically an Auto_Close macro and a reference to PowerShell, indicates a malicious intent to execute code. The ClamAV detection further supports this. The Auto_Close macro suggests that malicious code is designed to run automatically when the presentation is closed. The embedded URL, while marked as benign, is included as a potential IOC.

VBA macros detected medium OLE_VBA_MACROS

Document contains VBA macro code
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
