Valorant Anti-Cheat Update Turns $6,000 Cheating Hardware Into a “Paperweight,” Studio Mocks Cheaters on Social Media

Riot Games has updated Valorant’s Vanguard anti-cheat to target DMA-based cheating hardware, disrupting setups that cheat developers have used to bypass traditional software detection. The move has drawn attention because some cheaters claim expensive hardware rigs worth around $6,000 were rendered unusable after the update, though reports suggest the effect is temporary and can be reversed by reinstalling the operating system. Riot’s public response also fueled discussion, with an anti-cheat lead posting a mocking message on X aimed at the owners of the affected setups.
DMA, or Direct Memory Access, allows external devices to read and write system memory without going through the CPU in the usual way. While the technology has legitimate uses for developers, debuggers, and security researchers, it has increasingly been repurposed by cheat creators seeking to hide unauthorized tools from game-side detection. In competitive games like Valorant, where kernel-level anti-cheat software monitors the system for suspicious activity, DMA setups have become a workaround designed to separate the cheat logic from the main gaming PC.
A typical DMA cheating rig involves multiple pieces of hardware. One computer runs the game, while a second machine, such as a laptop or mini-PC, controls the cheat software. A DMA card is installed in the gaming PC to provide direct memory access, and custom firmware is often flashed onto the card to disguise it as a different device, such as a network adapter or storage controller. A hardware input emulator, often called a KMBox, is then used to make mouse and keyboard actions appear legitimate to the game. Together, these components allow cheats such as aimbots and wallhacks to operate with reduced risk of detection.
The latest Vanguard changes are believed to have introduced stronger IOMMU checks, which regulate how peripherals access memory and may interfere with DMA devices that attempt to operate through SATA or NVMe-style firmware tricks. Riot has not publicly detailed the exact method used to counter the cheating hardware, but the result appears to be a significant setback for users relying on these setups.
Reactions have been mixed. Many players have praised Riot for taking a hard line against cheating and for hitting offenders where it hurts. Others have raised concerns about the broader implications of kernel-level anti-cheat software, arguing that such deep system access can resemble malware and could introduce security or privacy risks if misused. The episode highlights the ongoing arms race between game publishers and cheat developers, where one side continually adapts to the other’s latest defenses.
