In recent studies, sophisticated attack vectors that use a Rowhammer bug have been developed. These attacks are dangerous, given that they can corrupt data stored in arbitrary memory rows without accessing them. Successful Rowhammer attacks require to flip data of the target cell. However, non-target cells are also corrupted by the attacks.

Detection of Rowhammer Attacks in SoCs with FPGAs
2020 IEEE European Test Symposium (ETS), 2020Heterogeneous SoCs integrate FPGAs and microprocessor cores on the same fabric to accelerate applications such as cryptography and deep learning. Since FPGAs share resources with the microprocessor cores, they can launch non-cacheable SDRAM transactions through direct FPGA-to-microprocessor SDRAM interface.

A new approach for rowhammer attacks
2016 IEEE International Symposium on Hardware Oriented Security and Trust (HOST), 2016Rowhammer is a hardware bug identified in recent commodity DRAMs: repeated row activations can cause bit flips in adjacent rows. Rowhammer has been recognized as both a reliability and security issue. And it is a classic example that layered abstractions and trust (in this case, virtual memory) can be broken from hardware level.

The Rowhammer Attack Injection Methodology
2016 IEEE 35th Symposium on Reliable Distributed Systems (SRDS), 2016This paper presents a systematic methodology to identify and validate security attacks that exploit user influenceable hardware faults (i.e., rowhammer errors). We break down rowhammer attack procedures into nine generalized steps where some steps are designed to increase the attack success probabilities. Our framework can perform those nine operations

Lecture Notes in Computer Science, 2019 MasterTo perform sophisticated rowhammer attacks, attackers need to repeatedly access the neighboring rows of target data. In DRAM, however, the physical addresses of neighboring rows are not always contiguous even if they are located before or after a ...

Triggering Rowhammer Hardware Faults on ARM
Proceedings of the 2018 Workshop on Attacks and Solutions in Hardware Security, 2018The rowhammer bug belongs to software-induced hardware faults, and has posed great security challenges to numerous systems. On x86, many approaches to triggering the rowhammer bug have been found; yet, due to several different reasons, the number of discovered approaches on ARM is limited.
