SMASH: Synchronized Many-Sided Rowhammer Attacks From JavaScript
Posted Apr 15, 2021
Authored by Kaveh Razavi, Herbert Bos, Cristiano Giuffrida, Pietro Frigo, Emanuele Vannacci, Finn de Ridder

In this paper, the authors show that under realistic assumptions, it is indeed possible to bypass TRR directly from JavaScript, allowing attackers to exploit the resurfaced Rowhammer bug inside the browser. In addition, their analysis reveals new requirements for practical TRR evasion. For instance, they discovered that activating many rows in rapid succession as shown in TRRespass may not always be sufficient to produce bit flips. The scheduling of DRAM accesses also plays an important role.

Cross-VM ASL INtrospection (CAIN)
Posted Aug 6, 2015

A new attack vector against memory de-duplication in Virtual Machine Monitors (VMM) was discovered where attackers can effectively leak randomized base addresses of libraries and executables in processes of neighboring Virtual Machines (VM).
