Apple has released three urgent updates to fix a bug called Spectre which could allow hackers to steal information from people’s computers and devices.
Last week, security researchers disclosed two major chip flaws affecting the chips which power almost all modern devices.
Anyone using an iPhone or iPad should install iOS 11.2.2, whilst there are two new software releases for Mac computers: macOS High Sierra 10.13.2 Supplemental Update and Safari 11.0.2.
Macs and iOS devices are vulnerable to Spectre attacks through code that can run in web browsers including Apple’s own Safari.
It’s not thought that hackers have built viruses or malware which exploit the vulnerabilities.
Apple gave users this advice in a blog post: ‘These issues apply to all modern processors and affect nearly all computing devices and operating systems.
‘All Mac systems and iOS devices are affected, but there are no known exploits impacting customers at this time.
‘Since exploiting many of these issues requires a malicious app to be loaded on your Mac or iOS device, we recommend downloading software only from trusted sources such as the App Store.’
