What it detects

This rule detects the Deno JavaScript runtime executing a payload retrieved from a remote HTTP or HTTPS URL, the second stage of a ClickFix campaign that abuses the Deno runtime to deliver an infostealer. Legitimate use of Deno to run code directly from a remote web address on an endpoint is uncommon.
