Riot Games Denies Claims of Vanguard Bricking PCs

Anti-Cheat Controversy Debunked: What Really Happened When Vanguard Met DMA Cheating Hardware

In the wake of accusations that Riot’s Vanguard anti‑cheat system was “bricking” players’ PCs, Riot Games issued clarifications emphasizing that only specialized DMA cheating devices—not users’ hardware—were being rendered inoperable. This article unpacks the technical reality, community reaction, and broader implications for anti‑cheat systems in competitive gaming.

The Spark: Allegations of ‘Bricked’ PCs

On May 21, 2026, Valorant players began accusing Riot Games’ Vanguard anti‑cheat of rendering their PCs unusable—even when the game wasn’t running. One user, “ogisada,” posted images and descriptions suggesting that DMA‑based cheat devices had become permanently inoperable, leading to claims of “bricked” hardware. Riot’s initial response—a tweet showing the devices with the caption “congrats to the owners of a brand new $6k paperweight”—was widely criticized for its tone‑deaf humor.

Riot’s Clarification: PCs Remain Unharmed

On May 22, Riot Games issued a statement clarifying that Vanguard does not brick PCs, components, or software. The company emphasized that the image in the tweet depicted specialized cheat hardware—not standard PC components. Riot explained that if a cheat setup continues to attempt unauthorized memory access after Vanguard’s protections are active, users might see hardware faults or instability—but this is expected behavior tied to IOMMU protections. Crucially, this affects only DMA‑based cheat devices; legitimate players are unaffected.
