Two years after Spectre and Meltdown, the x86 processor faces another side-channel exploit – only this time, it is based on sensing temperature While Spectre and Meltdown may be long forgotten, a microprocessor flaw using a side-channel attack, dubbed Platypus, is again haunting Intel and AMD. An international team of security researchers has found that fluctuations in software power consumption can be exploited to access sensitive data on Intel processors. The researchers describe power side-channel attacks as attacks that exploit fluctuations in power consumption to extract sensitive data such as cryptographic keys. In...
