Nethammer: Inducing Rowhammer Faults through Network Requests

, 2020
International audienceIn this paper, we present Nethammer, a remote Rowhammer attack without a single attacker-controlled line of code on the targeted system, i.e., not even JavaScript.

PThammer: Cross-User-Kernel-Boundary Rowhammer through Implicit Accesses

, 2020
Rowhammer is a hardware vulnerability in DRAM memory, where repeated access to memory can induce bit flips in neighboring memory locations. Being a hardware vulnerability, rowhammer bypasses all of the system memory protection, allowing adversaries to ...

An Analysis of HMB-based SSD Rowhammer

Rowhammer has been shown to be an extensive attack vector. In the years since its discovery, numerous exploits have been shown, attacking a wide range of targets from kernels, through web browsers to machine learning models. These attacks were not always

GuardION: Practical mitigation of DMA-based rowhammer attacks on ARM [PDF]

, 2018
Over the last two years, the Rowhammer bug transformed from a hard-to-exploit DRAM disturbance error into a fully weaponized attack vector. Researchers demonstrated exploits not only against desktop computers, but also used single bit flips to compromise

Exploiting correcting codes:On the effectiveness of ECC memory against rowhammer attacks

, 2019
Given the increasing impact of Rowhammer, and the dearth of adequate other hardware defenses, many in the security community have pinned their hopes on error-correcting code (ECC) memory as one of the few practical defenses against Rowhammer attacks ...

Implementation of Rowhammer Effect in gem5

, 2021
Modern computer memories have been shown to have reliability issues. The main memory is the target of a security attack called Rowhammer, which causes bit flips in adjacent victim cells of aggressor rows. Existing architectures simulator don't provide any implementation of unintended memory modifications like bit-flips.

In-Depth Analysis of DRAM Cells During Rowhammer: And a Novel Protection Method

, 2023
Rowhammer is a security exploit used to cause bit errors DRAM chips. Newer DRAM technologies are becoming more vulnerable to rowhammer attacks, and existing protec- tion methods are starting to reach their limits.
