What is GLitch?
GLitch is one part of our series of Rowhammer attacks. We started by breaking the EDGE browser and the cloud. Then we moved towards Android devices showing how to root them with bit flips. This time we wanted to show that also mobile phones can be attacked remotely via the browser.
Meet GLitch: the first instance of a remote Rowhammer exploit on ARM Android devices. This makes it possible for an attacker who controls a malicious website to get remote code execution on a smartphone without relying on any software bug.
You want to know what makes this attack even cooler? It is carried out by the GPU. This is the first GPU-accelerated Rowhammer attack.[…]
