JackHammer: Efficient Rowhammer on Heterogeneous FPGA-CPU Platforms
Zane Weissman, Thore Tiemann, Daniel Moghimi +3
After years of development, FPGAs are finally making an appearance on multi-tenant cloud servers. These heterogeneous FPGA-CPU architectures break common assumptions about isolatio…
TPM-FAIL: TPM meets Timing and Lattice Attacks
Daniel Moghimi, Berk Sunar, Thomas Eisenbarth +1
Trusted Platform Module (TPM) serves as a hardware-based root of trust that protects cryptographic keys from privileged system and physical adversaries. In this work, we perform a…
FortuneTeller: Predicting Microarchitectural Attacks via Unsupervised Deep Learning
Berk Gulmezoglu, Ahmad Moghimi, Thomas Eisenbarth +1
The growing security threat of microarchitectural attacks underlines the importance of robust security sensors and detection mechanisms at the hardware level. While there are studi…
Fallout: Reading Kernel Writes From User Space
Marina Minkin, Daniel Moghimi, Moritz Lipp +7
Recently, out-of-order execution, an important performance optimization in modern high-end processors, has been revealed to pose a significant security threat, allowing information…
Credential Masquerading and OpenSSL Spy: Exploring ROS 2 using DDS security
Vincenzo DiLuoffo, William R. Michalson, Berk Sunar
The trend toward autonomous robot deployments is on an upward growth curve. These robots are undertaking new tasks and are being integrated into society. Examples of this trend are…
SPOILER: Speculative Load Hazards Boost Rowhammer and Cache Attacks
Saad Islam, Ahmad Moghimi, Ida Bruhns +4
Modern microarchitectures incorporate optimization techniques such as speculative loads and store forwarding to improve the memory bottleneck. The processor executes the load specu…
