Apple warns iPhones, iPads and Mac computers hit by Intel flaw

It said that Apple Watch is not affected. Apple also added that since it would take a malicious app to set off Meltdown or Spectre, it recommends that iOS and Mac users install apps from a trusted source only, such as the App Store.

Besides, as per a report published on The guardian.com, Apple is also developing protections against the Spectre flaw for its Safari browser for iOS and macOS devices. Apple has already released mitigations in iOS 11.2, macOS 10.13.2, and tvOS 11.2 to help defend against Meltdown. In a new support document, Apple says that "all Mac systems and iOS devices are affected" by the vulnerability, but that there are no known exploits impacting customers right now...

Current updates to macOS and iOS protect against Meltdown, and Apple is working on providing better protections against Spectre.

On Wednesday, Alphabet Inc's Google and other security researchers disclosed two major chip flaws, one called Meltdown affecting only Intel Corp chips and one called Spectre affecting almost all computer chips made in the last decade. The company pledged to issue updates to the Safari web browser in the coming days "to help mitigate against Spectre", which affects processors from Intel and nearly all suppliers, including AMD and Arm Holdings. "We proceed to create and test encourage alleviations for these issues and will discharge them in up and coming updates of iOS, macOS, tvOS, and watchOS", the article states.

The two hardware bugs can be exploited to allow the memory content of a computer to be leaked.

Despite concern that fixes may slow down devices, Apple said its steps to address the Meltdown issue haven't dented performance.

There's no evidence that bad actors have yet exploited the bugs, but companies from Microsoft to Mozilla said they have worked to patch up vulnerabilities to their operating systems.

IDC estimated that there are 1.5bn PCs in use around the world today, out of which 90pc are powered by Intel processors.

Researchers at Google's Project Zero and academic institutions and discovered the issues past year and disclosed them this week. But someone, somewhere, blew the lid and tech giants are scrambling because the fear is that now the secret is out in the open, hackers could move fast to exploit these weaknesses.
