Dedup Est Machina: Memory Deduplication as an Advanced Exploitation Vector
2016
Memory deduplication, a well-known technique to reduce the memory footprint across virtual machines, is now also a default-on feature inside the Windows 8.1 and Windows 10 operating systems. Deduplication maps multiple identical copies of a …

ZebRAM: comprehensive and compatible software protection against rowhammer attacks
2018 · VU Research Portal
The Rowhammer vulnerability common to many modern<br/>DRAM chips allows attackers to trigger bit flips in a row<br/>of memory cells by accessing the adjacent rows at high<br/>frequencies. As a result, they are able to corrupt sensitive<br/>data …

Terminal brain damage: exposing the graceless degradation in deep neural networks under hardware fault attacks
2019 · arXiv (Cornell University)
Deep neural networks (DNNs) have been shown to tolerate brain damage: cumulative changes to the network's parameters (e.g., pruning, numerical perturbations) typically result in a graceful degradation of classification accuracy. However, the limits of this …

VPS
2019
Polymorphism and inheritance make C++ suitable for writing complex software, but significantly increase the attack surface because the implementation relies on virtual function tables (vtables). These vtables contain function pointers that attackers can potentially hijack …

NetCAT: Practical Cache Attacks from the Network
2020
Increased peripheral performance is causing strain on the memory subsystem of modern processors. For example, available DRAM throughput can no longer sustain the traffic of a modern network card. Scrambling to deliver the promised performance, …

Rage Against the Machine Clear: A Systematic Analysis of Machine Clears and Their Implications for Transient Execution Attacks
2021 · VU Research Portal
Since the discovery of the Spectre and Meltdown vulnerabilities, transient execution attacks have increasingly gained momentum. However, while the community has investigated several variants to trigger attacks during transient execution, much less attention has been …
