  "abstract": "Everyone knows and loves the famous line from the cinematic masterpiece where the IT-Security specialist asks the CPU architect: \"Warum leaked hier Strom?\" (Why is power leaking here?).",
  "description": "In this talk, we want to answer that question. We demonstrate how we can attack modern processors purely in software, relying on techniques from classical power side-channel attacks. We explain how we abuse the unprivileged access to energy-monitoring features of modern Intel and AMD CPUs. With PLATYPUS, we show how to steal cryptographic keys from the operating system or trusted-execution environments, and how to break kernel address-space layout randomization within seconds. Finally, we discuss the mitigations that prevent our attacks.",
