Generic And Automated Drive-By GPU Cache Attacks From The Browser
In this paper, the authors present the first GPU cache side-channel
attack from within the browser, more specifically from the
restricted WebGPU environment. The foundation for our generic and
automated attacks are self-configuring primitives applicable to a
wide variety of devices, which they demonstrate on a set of 11
desktop GPUs from 5 different generations and 2 vendors.
