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…
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…
MicroWalk: A Framework for Finding Side Channels in Binaries
Jan Wichelmann, Ahmad Moghimi, Thomas Eisenbarth +1
Microarchitectural side channels expose unprotected software to information leakage attacks where a software adversary is able to track runtime behavior of a benign process and ste…
MemJam: A False Dependency Attack against Constant-Time Crypto Implementations
Ahmad Moghimi, Thomas Eisenbarth, Berk Sunar
Cache attacks exploit memory access patterns of cryptographic implementations. Constant-Time implementation techniques have become an indispensable tool in fighting cache timing at…
CacheZoom: How SGX Amplifies The Power of Cache Attacks
Ahmad Moghimi, Gorka Irazoqui, Thomas Eisenbarth
In modern computing environments, hardware resources are commonly shared, and parallel computation is widely used. Parallel tasks can cause privacy and security problems if proper…
