Grazer Linuxtage 2019 speaker: Moritz Lipp
I am an PhD student at in the Secure Systems group at the Institute of Applied Information Processing and Communications at Graz University of Technology. I am the founder of pwmt.org, an open-source community creating functional and simplistic applications and libraries. I am interested in microarchitectural side-channel attacks and apiculture.
A Christmas Carol - The Spectres of the Past, Present, and Future
With the beginning of last year, two major security vulnerabilities have been disclosed: Meltdown and Spectre. While mitigations in software and hardware have been rolled out right away, new variants have been continuously released in the following months. With all those confusing names, how can you possibly still have a clear overview of all those vulnerabilities (SpectreV1, SpectreV2, Meltdown, Spectre-NG, SpectreRSB, L1TF, Foreshadow, ...)? With this talk, we present a novel classification that will ease the naming complexity of the current jungle of variants. Along with all different attacks, we will give an overview of all proposed mitigations and show how an attacker still can mount an attack despite the presence of implemented countermeasures. Furthermore, we will present new variants of the Meltdown attack, exploiting different parts of the CPU.
