The creator of a supposedly "undetectable" cheat for Call of Duty: Warzone has shut down its operation at the "request" of Activision.

As reported by Waypoint, the developer of the Userviz cheat – User101 – deleted all of the content of their website and said that they never intended to do anything illegal. This aimbot exploit – which automatically aims for users – rose to prominence last week due to its innovative approach, namely its use of machine learning which meant that it didn't need to hack a game to work. User101 said that they believed that this would work on any platform.

It wasn't limited to Call of Duty: Warzone, but a video demonstrating the tech in action in the shooter clearly attracted the gaze of Activision.

"This statement was not required," they said.

"However, at the request of Activision Publishing, Inc ('Activision'), I will no longer be developing or providing access to software that could be used to exploit their games. My intent was never to do anything illegal. At the end of the video that brought so much attention to this project, it stated “coming soon”. The software was never published.

"This type of technology has other actual assistive benefits, for example, by pointing a webcam at yourself you could control movement without the use of limbs. Unfortunately, because of its potential negative impact I will not be developing it further."

To date, more than 500,000 accounts have been banned from Call of Duty: Warzone for cheating.
