MITRE ATT&CK

T1059.005 Visual Basic

The file is an OLE document with VBA macros, including AutoOpen and Auto_Close, which are commonly used to execute malicious code upon opening or closing the document. ClamAV detections indicate it is a known trojan. The document body contains generic text about concerts and sales, serving as a lure to encourage macro execution. No specific scripts were extracted, but the presence of AutoOpen/Auto_Close macros strongly suggests the execution of malicious VBA code.
