ZeroLeak: Using LLMs for Scalable and Cost Effective Side-Channel Patching

no code implementations24 Aug 2023 M. Caner Tol, Berk Sunar

In this work, we explore the use of LLMs in generating patches for vulnerable code with microarchitectural side-channel leakages.

Don't Knock! Rowhammer at the Backdoor of DNN Models

1 code implementation14 Oct 2021 M. Caner Tol, Saad Islam, Andrew J. Adiletta, Berk Sunar, Ziming Zhang

To this end, we first investigate the viability of backdoor injection attacks in real-life deployments of DNNs on hardware and address such practical issues in hardware implementation from a novel optimization perspective.

An Optimization Perspective on Realizing Backdoor Injection Attacks on Deep Neural Networks in Hardware

no code implementations29 Sep 2021 M. Caner Tol, Saad Islam, Berk Sunar, Ziming Zhang

Recent works focus on software simulation of backdoor injection during the inference phase by modifying network weights, which we find often unrealistic in practice due to the hardware restriction such as bit allocation in memory.

FastSpec: Scalable Generation and Detection of Spectre Gadgets Using Neural Embeddings

1 code implementation25 Jun 2020 M. Caner Tol, Berk Gulmezoglu, Koray Yurtseven, Berk Sunar

In this work, we employ both fuzzing and deep learning techniques to automate the generation and detection of Spectre gadgets.

FortuneTeller: Predicting Microarchitectural Attacks via Unsupervised Deep Learning

no code implementations8 Jul 2019 Berk Gulmezoglu, Ahmad Moghimi, Thomas Eisenbarth, Berk Sunar

Therefore, we propose FortuneTeller, which for the first time leverages the superiority of RNNs to learn complex execution patterns and detects unseen microarchitectural attacks in real world systems.

SPOILER: Speculative Load Hazards Boost Rowhammer and Cache Attacks

3 code implementations1 Mar 2019 Saad Islam, Ahmad Moghimi, Ida Bruhns, Moritz Krebbel, Berk Gulmezoglu, Thomas Eisenbarth, Berk Sunar

We propose the SPOILER attack which exploits this leakage to speed up this reverse engineering by a factor of 256.

Undermining User Privacy on Mobile Devices Using AI

no code implementations27 Nov 2018 Berk Gulmezoglu, Andreas Zankl, M. Caner Tol, Saad Islam, Thomas Eisenbarth, Berk Sunar

Over the past years, literature has shown that attacks exploiting the microarchitecture of modern processors pose a serious threat to the privacy of mobile phone users.
