INTEL POWER GADGET INSTALLATION FAILED MAC DRIVER
This is because the Linux kernel ships with the powercap framework, a universal driver for interacting with RAPL interfaces and other power capping APIs, allowing easy reads of power consumption values.Īttacks on Windows and macOS are also possible, but in these cases, the Intel Power Gadget app must be installed on the attacked devices to allow the attackers to interact with the RAPL interface. Linux more vulnerable than the restĪccording to the research team, Platypus attacks work on Linux systems the best. In another test, they also retrieved data that was being processed inside Intel SGX secure enclaves.Ī Platypus attack that retrieved RSA private keys from an SGX enclave required the attacker to monitor RAPL data for 100 minutes, while an attack that retrieved AES-NI encryption keys from an SGX enclave and from the Linux kernel memory space took 26 hours. In tests, researchers said they bypassed KASLR by observing RAPL power consumption values for only 20 seconds, and then they retrieved data from the Linux kernel. However, researchers say that Platypus allows an attacker to bypass all these security systems by looking at variations in power consumption values. These can be encryption keys, passwords, sensitive documents, or any other type of information.Īccessing this kind of data is normally protected by a slew of security systems, such as kernel address space layout randomization (KASLR) or hardware-isolated trusted execution environments (TEEs), like Intel SGX. These "loaded values" refer to data loaded in the CPU. "Using PLATYPUS, we demonstrate that we can observe variations in the power consumption to distinguish different instructions and different Hamming weights of operands and memory loads, allowing inference of loaded values," researchers said. In a research paper published today, academics from the Graz University of Technology, the University of Birmingham, and the CISPA Helmholtz Center for Information Security have revealed how a Platypus attack can be used to determine what data is being processed inside a CPU by looking at values reported via the RAPL interface.

RAPL, which effectively lets firmware and software apps read how much electrical power a CPU is pulling in to perform its tasks, is a system that has been used for years to track and debug application and hardware performance. RAPL, which stands for Running Average Power Limit, is a component that allows firmware or software applications to monitor power consumption in the CPU and DRAM. Named Platypus, an acronym for " Power Leakage Attacks: Targeting Your Protected User Secrets," the attack targets the RAPL interface of Intel processors.
