Encoded PowerShell Command Detection
This rule detects PowerShell commands that utilize encoded arguments such as '-enc', '-ec', or '-en'. Adversaries often use encoded PowerShell commands to obfuscate their malicious scripts, making it harder for security tools and analysts to detect and understand their activities. The rule specifically looks for the execution of 'powershell.exe' or 'powershell_ise.exe' with these encoding flags and attempts to capture and decode the obfuscated command.
