RowHammer Vulnerability Counter (RVC): Redefining RowHammer Detection with Victim-Centric Tracking
The Rowhammer vulnerability poses an increasing challenge with newer generations of DRAM and aggressive technology scaling. Existing mitigation techniques, such as Graphene, Twice, and Hydra, primarily rely on tracking activation counts for each row and issuing refreshes when a row reaches a predefined tracking threshold.

FP-Rowhammer: DRAM-Based Device Fingerprinting
Proceedings of the 20th ACM Asia Conference on Computer and Communications SecurityDevice 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 ...

It’s Hammer Time: How to Attack (Rowhammer-based) DRAM-PUFs
, 2018 Physically Unclonable Functions (PUFs) are still considered promising technology as building blocks in cryptographic protocols. While most PUFs require dedicated circuitry, recent research leverages DRAM hardware for PUFs due to its intrinsic properties ...

Nethammer: Inducing Rowhammer Faults through Network Requests
, 2018 A fundamental assumption in software security is that memory contents do not change unless there is a legitimate deliberate modification. Classical fault attacks show that this assumption does not hold if the attacker has physical access.

Randomized Line-to-Row Mapping for Low-Overhead Rowhammer Mitigations
, 2023 Modern systems mitigate Rowhammer using victim refresh, which refreshes the two neighbours of an aggressor row when it encounters a specified number of activations.

Schrödinger's Toolbox: Exploring the Quantum Rowhammer Attack
2025 IEEE International Conference on Quantum Computing and Engineering (QCE)Residual cross-talk in superconducting qubit devices creates a security vulnerability for emerging quantum cloud services. We demonstrate a Clifford-only Quantum Rowhammer attack-using just X and CNOT gates-that injects faults on IBM's 127-qubit Eagle processors without requiring pulse-level access.
