A series of flaws have been discovered in Intel, AMD, and ARM chipsets that allow speculative references to be probed for privileged data. "Meltdown" is a flaw currently believed to affect only Intel processors and "melts security boundaries which are normally enforced by the hardware". "Spectre" is a flaw that affects Intel, AMD, and ARM processors due to the way "speculative execution" is handled. Both could theoretically be used to read information from a computer's memory, including private information like passwords, photos, messages, and more. Apple has apparently already started patching Meltdown in macOS. Here's what you need to know. January 15, 2018: No, iOS 11.2.2's Spectre patch isn't crippling older iPhones. Sigh. A strange story began gaining traction over the weekend. It was based on a set of comparative CPU benchmarks for an iPhone before and after the iOS 11.2.2, posted to the internet, that appeared to show significant addition slowdown post-update. A...
