What Intel's Foreshadow Flaw Means for the Future of Cryptocurrency
Yet another dire security flaw was unveiled Tuesday with potential ripple effects across the tech world, including for cryptocurrency projects seeking to leverage certain hardware devices. Following a pair of bugs unveiled earlier this year, the Foreshadow vulnerability impacts all Intel’s Software Guard Extensions (SGX) enclaves, a special, supposedly extra-secure region of chip often used for storing sensitive data. In short, while the enclave is supposed to be tamper-proof, a group of researchers found a way for an attacker to steal the information it stores. For many, Meltdown and Spectre were spooky enough. The bugs impacted every single Intel chip, the hardware powering most of the world’s computers. But, since it wasn’t so easy to execute, there weren’t many real-world attacks. Foreshadow might not sound as bad because it impacts a more specific type of Intel hardware: SGX. However, since many cryptocurrency projects plan to use this technology, Foreshadow
