Valorant's anti-cheat has rendered certain pricey cheat hardware ineffective.

      Riot Games' contentious Vanguard anti-cheat system has garnered renewed scrutiny following a recent update that reportedly rendered certain costly Valorant cheat hardware inoperable. Riot took a jab at hardware cheaters on X, stating, “congrats to the owners of a brand new $6k paperweight,” after the update seemingly blocked DMA-based cheating devices that utilize expensive external hardware.

      This remark ignited discussions about the actual impact of Vanguard. Some discussions suggested that the issue was related to SSD damage; however, Riot clarified that Vanguard does not harm PC hardware or disable genuine SSDs. The update is aimed at cheat hardware and firmware designed to circumvent Valorant’s anti-cheat protocols.

      What is DMA cheating?

      DMA, or Direct Memory Access, is a standard hardware function that allows devices to access system memory directly without sending each request through the CPU. In cheating scenarios, DMA can be exploited to read game memory from outside the standard software environment.

      A DMA device connects to a PC via PCIe, enabling cheaters to run tools like radar, wallhacks, or ESP using a separate machine. Such setups tend to be costly and utilize specialized programmable hardware disguised as normal PC components, making them difficult to detect.

      What changes did Riot implement?

      The most recent Vanguard update appears to focus on a vulnerability exploited by high-end cheating setups that rely on external hardware instead of traditional software. These devices mimic trusted components, such as storage drives, thus gaining access to game data while evading straightforward detection.

      In response, Riot seems to be tightening the enforcement of IOMMU (Input-Output Memory Management Unit), a hardware-level memory protection system that governs which connected devices can access certain data. By restricting these permissions, Vanguard can stop suspicious external hardware from accessing live game data, effectively eliminating the advantage provided by DMA cheats.

      Did Riot “brick” actual SSDs?

      Riot has stated that Vanguard does not damage hardware, disable devices, or render PCs, components, or software inoperable. The company clarifies that the devices impacted are DMA cheat tools used for Valorant cheating, not standard SSDs or PC components. Some users affected by the update have reported needing to reinstall Windows because their systems became nonfunctional.

      Riot claims that instability arises when IOMMU protections are activated, and a cheat setup continues to attempt access to protected memory. In such instances, the system might experience hardware faults or instability. This behavior is characteristic of IOMMU when a device tries to access memory it is not permitted to.

      Why did this lead to a trust debate?

      Community responses have been mixed. Many players on X and Reddit ridiculed the affected cheaters, asserting that anyone spending large sums on DMA cheat hardware deserved to lose it.

      Conversely, other players expressed concern over the implications of this situation. Some Reddit users questioned whether a kernel-level anti-cheat should have the authority to block hardware at such a degree. Players are wondering about the potential repercussions for legitimate hardware being mistakenly flagged. There are worries that a false positive could inhibit access to a genuine NVMe or SATA drive and necessitate a Windows reinstallation. While Riot has denied that Vanguard disables legitimate PC devices or bricks computers, not everyone is reassured.

      Halting cheaters is critical in a competitive game like Valorant, but kernel-level anti-cheats invite ethical concerns, as they operate deep within a player's system. When an anti-cheat can interfere with hardware functionality, even for justified reasons, it creates a trust issue between the game developer and the player.
