‘Call of Duty: Warzone’ and ‘Vanguard’ anti-cheat updates embrace a kernel-level driver | Engadget

Activision has unveiled its massive, new strategy to squashing hackers in Call of Duty: Warzone and Vanguard, and it is a two-pronged system known as RICOCHET Anti-Cheat. The first stage is a sequence of server-side enhancements that can higher establish and take away cheaters from video games, and that is scheduled to hit Warzone with the Pacific replace later this yr. These new server instruments shall be stay in Vanguard when it comes out on November fifth.

The second prong is a PC kernel-level driver designed to watch the deepest stage of each participant’s rig whereas they’re in-game, in an effort to cease exterior software program from sneaking in by way of this again door. The kernel, or ring 0, is probably the most privileged stage of any PC, granting entry to each layer of {hardware}, and customarily reserved for issues like graphics card drivers and trusted bits of the working system. The RICOCHET Anti-Cheat kernel-level driver will solely activate when Warzone or Vanguard is lively; it is not an always-on scenario.

While working within the kernel is not unusual for anti-cheat software program, that is doubtless probably the most regarding a part of Activision’s new plans for a lot of gamers.

With these classes in thoughts, Activision has pressured that RICOCHET will solely be lively when the related recreation is stay, saying particularly, “the driver shuts down when you exit the game and turns on when you start a new game.”

The kernel-level driver will hit Warzone alongside the Pacific replace this yr, and it will come to Vanguard at a later date.

Cheating has been a big downside in Call of Duty: Warzone for an extended whereas now. Activision has banned greater than 500,000 accounts for the reason that recreation’s launch, although it is not unusual for matches to be riddled with aimbots and low-cost hacks to today. Players have been screaming for a sturdy anti-cheat system in Warzone and different Call of Duty titles, and RICOCHET is Activision’s kernel-level, not-always-on reply.
