Riot Games Comments on Vanguard Bricking PCs Rumors

On May 19th, an update to Riot Games’ Vanguard anti-cheat software appeared to be causing problems with devices that use direct memory access (DMA), particularly those with SATA or NVMe drives. Reports quickly spread online, with some players claiming Vanguard was damaging their computers and sharing images of error screens. Riot Games added to the concern when they posted a picture of cheating devices labeled a “$6k paperweight,” seemingly referencing the issues. Users reported that even after removing Vanguard, their DMA firmware was no longer working, and some experienced warnings about their computer’s IOMMU security features.
