Copilot autorun=1 URL click triggering unattended prompt execution
Detects Microsoft Copilot interaction URLs containing the 'autorun=1' parameter alongside a 'q=' prompt parameter. This combination indicates a potential attempt to execute a prompt in the user's Copilot session without explicit user confirmation upon link click, a technique sometimes referred to as a CoSnitch or one-click attack.
