Hackers have infested video games for as long as gaming has existed. In particular, the Call of Duty franchise has been the target of many hackers dating as far back as the Call of Duty: World at War era.
Nowadays, cheating is quite common, and many hackers are finding new ways to ruin the fun for others. Warzone had its ups and downs throughout its release. When the highly-acclaimed battle royale was released, the hackers were rampant.
After numerous complaints and multiple ban waves, the situation just kept getting worse until the release of Activision's very own kernel-level anti-cheat, RICOCHET.
The release of RICOCHET helped take down a lot of hackers, making the situation much better. However, despite Raven Software's commendable efforts, the hackers seemed to have found a way around the anti-cheat.
A Redditor, u/aBipolarTree, posted about the influx of blatant hackers in Warzone. The OP agreed that after the introduction of RICOCHET, cheating was reduced drastically. However, it was not until recently that the OP started running into multiple blatant hackers.
