List of kernel-level anti cheats

2026-05-25T22:03:45Z

Ednovstormbrewer: Despite overwhelming list of games, I added more games on the list that stand out the most. Also, one thing needed corrected. ARC Raiders uses Easy Anticheat, not Anticheat Expert.

Talk:List of kernel-level anti cheats

2026-05-25T21:59:33Z

Ednovstormbrewer: /* Problem with listing every game */ Reply

==Problem with listing every game==

For EA anti cheat or Vanguard every game can be easily listed without any problems but for BattlEye or Easy Anti-cheat there are so many games that use these its just not practical. Linking to something like SteamDB [https://steamdb.info/tech/AntiCheat/BattlEye/] is probably a better idea. Maybe games that are considered "notable" can be listed like GTA V, Rainbow 6 Siege, etc.

[[User:Kadencant|Kadencant]] ([[User talk:Kadencant|talk]]) 03:30, 24 February 2026 (UTC)

:[https://www.pcgamingwiki.com/wiki/Home PCGamingWiki] has pages dedicated to various anti-cheat solutions, and even various forms of DRM (Denuvo for example), might be easier to link there instead. [[User:Saya|Saya]] ([[User talk:Saya|talk]]) 15:23, 5 April 2026 (UTC)
::[https://areweanticheatyet.com/ AreWeAntiCheatYet] has a table list of games with anti-cheat along with a search query to find what you're looking for. [[User:Ednovstormbrewer|Ednovstormbrewer]] ([[User talk:Ednovstormbrewer|talk]]) 21:59, 25 May 2026 (UTC)

Kernel level anti-cheats

2025-07-03T17:43:24Z

Ednovstormbrewer: Revised short list under Further reading pertaining to Rainbow Six Siege

'''Kernel-level anti-cheat''' is a subset of anti-cheat dedicated towards running above the user level. These types of anti-cheat, such as [[Easy Anti-Cheat|Easy Anticheat]] (EAC), have grown in popularity among large developers for their online multiplayer games.{{Citation needed}} Alongside this rise in popularity is increasing concern from both consumers regarding their privacy with the use of this software,{{Citation needed}} and from security professionals who recognize the significant risks of kernel-level software being breached.{{Citation needed}}

==How it works==
Kernel level anti-cheats run at the {{Wplink|Kernel (operating system)|kernel level}}; the deepest and most authoritative level of the computer. In layman's terms, this essentially means the software is capable of tracking every process occurring on a computer, and additionally exhibit control if necessary. Alternatives to kernel level anticheat include user level anticheat which runs as a standard process on the player's machine, and server side anticheat which leaves the user's machine untouched and solely operates on the game's servers.

The arms race between hacking and anticheat software has seen hackers better able to circumvent user level anticheat in recent years, pushing more anticheat developers to demand kernel access from players and more developers to require use of a kernel anticheat to access their games.

==Consumer impact summary==
===Privacy concerns===
Kernel-level anti-cheat has access to every process that runs on a computer, from a simple video running in the background, to processes that may be more private for the user. As this software is designed to run on startup,<ref>{{Cite web |last=Rigney |first=Ryan K. |date=23 Feb 2024 |title=The Gamers Do Not Understand Anti-Cheat |url=https://www.pushtotalk.gg/p/the-gamers-do-not-understand-anti-cheat |access-date=2025-06-10 |website=Push To Talk}}</ref> this means even if the intended game the software was installed for is not currently running, it retains the capability to track the user's behaviors. This can range from gathering data that could be sold to advertisers to, if the software itself is hijacked by a malicious actor, the harvesting of sensitive personal information.

===Security concerns===
As kernel-level software holds the highest authorization on the hardware of a user,<ref>{{Cite web |last=Litchfield |first=Ted |date=27 Feb 2024 |title=According to experts on kernel level anticheat, two things are abundantly clear: 1) It's not perfect and 2) It's not going anywhere |url=https://www.pcgamer.com/according-to-experts-on-kernel-level-anticheat-two-things-are-abundantly-clear-1-its-not-perfect-and-2-its-not-going-anywhere/ |url-status=live |archive-url=https://web.archive.org/web/20250406200223/https://www.pcgamer.com/according-to-experts-on-kernel-level-anticheat-two-things-are-abundantly-clear-1-its-not-perfect-and-2-its-not-going-anywhere/ |archive-date=2025-04-06 |access-date=2025-06-10 |website=PC Gamer}}</ref> this is favorable towards malicious actors.

If a malicious actor was to discover a security issue in a kernel level anti-cheat significant enough to allow them to hijack the software, they would be able to directly execute code at its level of access, allowing them to bypass security measures put in place by the {{Wplink|operating system}} and {{Wplink|Antivirus software|anti-virus software}}.

This is not a purely hypothetical scenario; it has already taken place in an incident with the popular {{Wplink|Gacha game|gacha}} co-op adventure [[Genshin Impact|''Genshin Impact'']], where the game's anti-cheat '''mhyprot2.sys''<nowiki/>' was hijacked by malicious actors to disable users' anti-virus software, with the intent of distributing {{Wplink|ransomware}}.<ref>{{Cite web |last=Soliven |first=Ryan |last2=Kimura |first2=Hitomi |date=2022-08-24 |title=Ransomware Actor Abuses Genshin Impact Anti-Cheat Driver to Kill Antivirus |url=https://www.trendmicro.com/en_us/research/22/h/ransomware-actor-abuses-genshin-impact-anti-cheat-driver-to-kill-antivirus.html}}</ref>

Another perfect example is Hotta Studios' Tower of Fantasy game. Users have reported that the kernel-level anticheat 'ksophon_x64.sys' has caused BSOD along with the DPC_WATCHDOG_VIOLATION. This incident occurs when the game is uninstalled, launched, closed, or even running before the new publisher Perfect World Games. As of now, since the update by the company, the file doesn't appear to exist in System32/drivers.

Kernel level anti-cheats

2025-07-03T17:37:03Z

Ednovstormbrewer: Revised last paragraph under Security concerns. Added links pertaining to kernel-level anticheats to Helldivers 2 and Rainbow Six Siege as an example of Linux gamers being unable to launch the game.

If a malicious actor was to discover a security issue in a kernel level anti-cheat significant enough to allow them to hijack the software, they would be able to directly execute code at its level of access, allowing them to bypass security measures put in place by the {{Wplink|operating system}} and {{Wplink|Antivirus software|anti-virus software}}.

Kernel level anti-cheats

2025-07-02T19:17:01Z

Ednovstormbrewer: /* Added another paragraph to Security Concerns to address history with Hotta Studios and more companies using kernel-level anticheats under Further reading */

'''Kernel-level anti-cheat''' is a subset of anti-cheat dedicated towards running above the user level. These types of anti-cheat, such as [[Easy Anti-Cheat|Easy Anticheat]] (EAC), have grown in popularity among large developers for their online multiplayer games.{{Citation needed}} Alongside this rise in popularity is increasing concern from both consumers regarding their privacy with the use of this software,{{Citation needed}} and from security professionals who recognize the significant risks of kernel-level software being breached.{{Citation needed}}

==How it works==
Kernel level anti-cheats run at the {{Wplink|Kernel (operating system)|kernel level}}; the deepest and most authoritative level of the computer. In layman's terms, this essentially means the software is capable of tracking every process occurring on a computer, and additionally exhibit control if necessary. Alternatives to kernel level anticheat include user level anticheat which runs as a standard process on the player's machine, and server side anticheat which leaves the user's machine untouched and solely operates on the game's servers.

The arms race between hacking and anticheat software has seen hackers better able to circumvent user level anticheat in recent years, pushing more anticheat developers to demand kernel access from players and more developers to require use of a kernel anticheat to access their games.

==Consumer impact summary==
===Privacy concerns===
Kernel-level anti-cheat has access to every process that runs on a computer, from a simple video running in the background, to processes that may be more private for the user. As this software is designed to run on startup,<ref>{{Cite web |last=Rigney |first=Ryan K. |date=23 Feb 2024 |title=The Gamers Do Not Understand Anti-Cheat |url=https://www.pushtotalk.gg/p/the-gamers-do-not-understand-anti-cheat |access-date=2025-06-10 |website=Push To Talk}}</ref> this means even if the intended game the software was installed for is not currently running, it retains the capability to track the user's behaviors. This can range from gathering data that could be sold to advertisers to, if the software itself is hijacked by a malicious actor, the harvesting of sensitive personal information.

===Security concerns===

It is based on a modified version of the Linux kernel and other open-source software, designed primarily for touchscreen-based mobile devices such as smartphones and tablets, but is also used in smart TVs, cameras, in-car infotainment systems, etc.{{Citation needed}}

==Consumer impact summary==
Google, as the developer of Android, has faced scrutiny over privacy concerns, short software support lifespans, patent disputes, and anti-competitive behaviors.{{Citation needed}}

Google encourages the use of their [https://developer.android.com/google/play/integrity/overview Play Integrity API], a mechanism for Android applications to detect whether they are running on a non-OEM version of Android. This is employed mostly to prevent users from running Android versions with anti-consumer features removed, i.e. ads and unconsented data collection. For example, the Android YouTube app which leverages the API to detect whether it has been patched to remove ads, in which case it will refuse to play back videos.

==Incidents==
This is a list of all consumer protection incidents related to this software. Any incidents not mentioned here can be found in the [[:Category:{{PAGENAME}}|{{PAGENAME}} category]].

===Data collection===
{{Main|Android Data Collection}}
Android mobile devices, even when minimally configured, collect and share with Google extensive user data with little options for opting-out, raising privacy concerns.

===Android System Safety Core silent install===
{{Hatnote|Full article: [[Android System SafetyCore]]}}
In January 22, 2025, Google quietly rolled out Android System SafetyCore to all Android devices. The installation of the program neither informed consumers that it was installed, nor did it request consumers to install it onto their devices.

'''OEM Locked Bootloaders'''

''Article:'' [[Motorola]]

In North America, Many of Android devices like phones or tablets will not allow consumers to unlock and do what they want to modify the software. Therefore, it has been incredibly difficult and nearly impossible to root and install custom ROMs into the device unless an exploit has been found.
