According to:

"Infinity Ward Tweets that more bans are on the way for those found cheating in Call of Duty: Modern Warfare and Warzone. You have been warned:

1. Cheating will not be tolerated. More banwaves are coming. If you receive a ban it is for unauthorized manipulation of game data. Don't fall for unscrupulous services offering cheats and modifications, these are fraudulent. For a list of security and enforcement policy details please visit https://support.activision.com/mwpolicy

2. Please do not use unauthorized 3rd party software to mod or hack. This includes tools such as hex editors, that equip items you have not acquired properly. We define this is cheating and there is no place for that in our game. This is a bannable offense and you risk losing your account.

3. Unauthorized 3rd party software includes, but is not limited to aimbots, wallhacks, trainers, stats hacks, texture hacks, leaderboard hacks, injectors, hex editors or any software used to deliberately modify game data or memory. Don't do it. This may result in being banned.

4. Avoid tutorials and services that offer ways to modify your camo. Anything that suggests altering the memory on your console or PC in order to acquire new gear, items or loadouts beyond what is offered in game is a hack, and is considered cheating. We will enforce accordingly, which may result in being banned. "
