T1059.001 PowerShell T1059.005 Visual Basic

The sample contains VBA macros that utilize CreateObject to execute a PowerShell command. The PowerShell command is obfuscated but appears to download a file from 'http://www.example.com/download.exe' and save it as 'C:\Users\Public\Documents\example.exe' before executing it. The VBA macro itself also contains obfuscated code that appears to be part of the download and execution chain.
