Microarchitectural Leakage Templates and Their Application to Cache-Based Side Channels
Ahmad Ibrahim, Hamed Nemati, Till Schlüter +2
The complexity of modern processor architectures has given rise to sophisticated interactions among their components. Such interactions may result in potential attack vectors in te…
Osiris: Automated Discovery of Microarchitectural Side Channels
Daniel Weber, Ahmad Ibrahim, Hamed Nemati +2
In the last years, a series of side channels have been discovered on CPUs. These side channels have been used in powerful attacks, e.g., on cryptographic implementations, or as bui…
BGPeek-a-Boo: Active BGP-based Traceback for Amplification DDoS Attacks
Johannes Krupp, Christian Rossow
Amplification DDoS attacks inherently rely on IP spoofing to steer attack traffic to the victim. At the same time, IP spoofing undermines prosecution, as the originating attack inf…
Padding Ain't Enough: Assessing the Privacy Guarantees of Encrypted DNS
Jonas Bushart, Christian Rossow
DNS over TLS (DoT) and DNS over HTTPS (DoH) encrypt DNS to guard user privacy by hiding DNS resolutions from passive adversaries. Yet, past attacks have shown that encrypted DNS is…
ret2spec: Speculative Execution Using Return Stack Buffers
Giorgi Maisuradze, Christian Rossow
Speculative execution is an optimization technique that has been part of CPUs for over a decade. It predicts the outcome and target of branch instructions to avoid stalling the exe…
Speculose: Analyzing the Security Implications of Speculative Execution in CPUs
Giorgi Maisuradze, Christian Rossow
Whenever modern CPUs encounter a conditional branch for which the condition cannot be evaluated yet, they predict the likely branch target and speculatively execute code. Such pipe…
