This software is part of the open-source component of our paper "Drammer: Deterministic Rowhammer Attacks on Mobile Devices", published in ACM Computer and Communications Security (CCS) 2016. It allows you to test whether an Android device is vulnerable to the Rowhammer bug. It does not allow you to root your device.
This code base contains the source for our Android GUI app, which is a wrapper around the native, C/C++-based mobile Rowhammer test implementation found in this repo.
If you don't want to build the test yourself, we also provide a pre-built Android app.
This app optionally collects basic statistics on the type of device and test results so that we can gain insights into the number and type of vulnerable devices in the wild, so please consider sharing them for science.
If, for some weird reason, you think running this code broke your device, you get to keep both pieces.
