Detects remote PowerShell execution initiated by processes associated with Remcos RAT or Optimax. The rule specifically looks for PowerShell or cmd.exe processes executing commands containing 'IEX', 'Invoke-Expression', 'DownloadString', or a specific IP address (62.102.148.212), where the initiating parent process is identified as 'Remcos' or 'Optimax'. This indicates a potential compromise and execution of malicious code via a known RAT.
