What it detects

This rule detects a hidden execution-policy-bypass PowerShell command that pulls a payload from an index.php grab endpoint which is the ClickFix stager of the TELEPUZ malware-as-a-service delivered through Vidar chains. Victims are lured into pasting the command from a fake verification prompt. The specific grab API path combined with bypass flags marks the malicious download.
