🚨 Riot atualiza o Vanguard para combater hardwares de cheats DMA avançados, podendo danificar dispositivos. Segundo relatos, a nova atualização do anti-cheat da Riot danifica o firmware de dispositivos utilizados nesse tipo de trapaça ao detectá-los. Os aparelhos podem ser reparados, mas a prática levantou discussões. A atualização mira hardwares com firmware SATA e NVMe modificados, usados para ler a memória do jogo e burlar sistemas anti-cheat tradicionais. A Riot também teria trabalhado com fabricantes como ASUS, MSI, Gigabyte e ASRock para corrigir vulnerabilidades relacionadas ao acesso DMA.

Well, that escalated quickly. There’s been a wave of claims by cheaters about Vanguard “bricking” their PCs, so let’s clear that up: Vanguard does not damage hardware or disable your devices. The photo we posted is a picture of cheat hardware devices that are sold explicitly for cheating in VALORANT (not normal PCs or PC components). Through our latest updates, Vanguard now makes those devices worthless for VAL, but does not in any way brick PCs or PC components or PC software. Our latest update enforces standard platform security features, like the Input-Output Memory Management Unit (IOMMU), on accounts identified as using Direct Memory Access (DMA) cheating devices. These protections are already part of modern systems and when enabled, they block DMA cheat devices (such as those shown in the photo) from accessing memory in downstream applications, like our games. If a cheat setup continues attempting to cheat after those protections are enabled, the system may generate hardware faults or instability. This is expected behavior under IOMMU when attempts are made to read protected memory. Disabling IOMMU allows the cheat device to function again, but IOMMU will still be required to play our games. This means the cheat device won’t work with our games, but your PC isn’t “bricked.” We would not, and cannot, impact your PC’s functionality in any other fashion. This functionality only applies to systems attempting to use DMA cheat devices, and players who are not using DMA-based cheat setups are not affected. We’ll keep investing in anti-cheat to protect competitive integrity, and we’ll keep being as transparent as possible about how those systems work.
