MITRE ATT&CK

T1059.005 Visual Basic T1059.001 PowerShell T1204.002 Malicious File

The file is a malicious Office document containing VBA macros. The presence of ShellExecute and GetObject API calls, along with the 'macros.bas' artifact, strongly suggests that the VBA code is designed to execute arbitrary commands or download additional payloads. The ClamAV detection further confirms its malicious nature. The exact intent of the script is not fully discernible due to potential obfuscation, but it is highly likely to be a downloader or initial execution vector.
