VBScript Process Initiating File Downloads or Executing System Utilities
This rule detects instances where 'wscript.exe' or 'cscript.exe' (VBScript interpreters) initiate processes that attempt to download files from the internet (HTTP, HTTPS, FTP) or from network shares, or execute common system utilities often used for file transfer or execution like 'net.exe', 'certutil.exe', or 'bitsadmin.exe'. This pattern is indicative of multi-stage VBScript loaders often used in phishing campaigns to retrieve and execute further malicious payloads.
