Rowhammer.js: A Remote Software-Induced Fault Attack in JavaScript
As DRAM has been scaling to increase in density, the cells are less isolated from each other. Recent studies have found that repeated accesses to DRAM rows can cause random bit flips in an adjacent row, resulting in the so called Rowhammer bug. This bug has already been exploited to gain root privileges and to evade a sandbox, showing the severity of faulting single bits for security. However, these exploits are written in native code and use special instructions to flush data from the cache.
In this paper we present Rowhammer.js, a JavaScript-based implementation of the Rowhammer attack. Our attack uses an eviction strategy found by a generic algorithm that improves the eviction rate compared to existing eviction strategies from 95.2% to 99.99%. Rowhammer.js is the first remote software-induced hardware-fault attack. In contrast to other fault attacks it does not require physical access to the machine, or the execution of native code or access to special instructions. As JavaScript-based fault attacks can be performed on millions of users stealthily and simultaneously, we propose countermeasures that can be implemented immediately.
