- Row hammer - Wikipedia
Rowhammer (also written as row hammer or RowHammer) is a computer security exploit that takes advantage of an unintended and undesirable side effect in dynamic random-access memory (DRAM) in which memory cells interact electrically between themselves by leaking their charges, possibly changing the contents of nearby memory rows that were not
- Fundamentally Understanding and Solving RowHammer
RowHammer is the phenomenon in which repeatedly accessing a row in a real DRAM chip causes bitflips (i e , data corruption) in physically nearby rows This phenomenon leads to a serious and widespread system security vulnerability, as many works since the original RowHammer paper in 2014 have shown
- The Rowhammer: the Evolution of a Dangerous Attack | Infosec
Back in 2015, security researchers at Google's Project Zero team demonstrated how to hijack an Intel-compatible PCs running Linux by exploiting the physical weaknesses in certain varieties of DDR DRAM (double data rate dynamic random-access memory) chips
- Rowhammer Attacks in Dynamic Random-Access Memory and Defense Methods
Rowhammer is a security vulnerability in DRAM, enabling an attacker to change the data stored within memory cells Rowhammer attacks take advantage of the physical proximity of these cells within the memory array
- What Is Row Hammer? How It Works Examples | Twingate
Row Hammer is a security exploit that targets certain types of dynamic random-access memory (DRAM) chips It leverages a vulnerability where repeatedly accessing a row of memory cells can cause bit flips in adjacent rows
- RowHammer: A Retrospective | IEEE Journals Magazine | IEEE Xplore
RowHammer is caused by a hardware failure mechanism called DRAM disturbance errors, which is a manifestation of circuit-level cell-to-cell interference in a scaled memory technology
- RowHammer
Outline Why does RowHammer happen? What is its working mechanism? How to perform the attack in practice? Challenges? Attack consequences? Mitigations?
- Test DRAM for bit flips caused by the rowhammer problem
"Rowhammer" is a problem with recent DRAM modules in which repeatedly accessing a row of memory can cause bit flips in adjacent rows This repo contains a program for testing for the rowhammer problem which runs as a normal userland process
