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

The sample contains VBA macros that construct a PowerShell command to download and execute a payload. The macro dynamically builds a URL from concatenated strings, which appears to be a downloader. The ClamAV detection and the presence of WinExec API calls further support its malicious nature.
