MITRE ATT&CK

T1059.005 Visual Basic T1059.001 PowerShell

The file contains VBA macros, and a critical heuristic indicates the use of the Shell() function, suggesting an attempt to execute arbitrary commands. The presence of 'macros.bas' and ClamAV detections further support malicious intent. The document body is a generic template and does not provide specific lures.
