RAMPART: RowHammer Mitigation and Repair for Server Memory Systems

, 2023
RowHammer attacks are a growing security and reliability concern for DRAMs and computer systems as they can induce many bit errors that overwhelm error detection and correction capabilities.

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.

FP-Rowhammer: DRAM-Based Device Fingerprinting

Proceedings of the 20th ACM Asia Conference on Computer and Communications Security
Device fingerprinting leverages attributes that capture heterogeneity in hardware and software configurations to extract unique and stable fingerprints. Fingerprinting countermeasures attempt to either present a uniform fingerprint across different devices through normalization or present different fingerprints for the same device each time through ...

TeleHammer: A Formal Model of Implicit Rowhammer

, 2019
The rowhammer bug allows an attacker to gain privilege escalation or steal private data. A key requirement of all existing rowhammer attacks is that an attacker must have access to at least part of an exploitable hammer row. We refer to such rowhammer attacks as PeriHammer.

SoK: Rowhammer on Commodity Operating Systems

Proceedings of the 19th ACM Asia Conference on Computer and Communications Security
Rowhammer has drawn much attention from both academia and industry in the past years as rowhammer exploitation poses severe consequences to system security. Since the first comprehensive study of rowhammer in 2014, a number of rowhammer attacks have been demonstrated against dynamic random access memory (DRAM)-based commodity systems to break software ...
