Spectre smartphone security flaw – what happens next? Can Spectre be fixed? We’re still learning more about Spectre as this story develops, but you’ll be pleased to hear that companies are already making moves to protect your devices. Apple will be rolling out various updates and fixes for both Spectre and Meltdown (which affects MacBooks and iMacs) over the coming days. The company says it has already ‘released mitigations in iOS 11.2, macOS 10.13.2, and tvOS 11.2’. Apple will now be publishing updates for Safari to help defend against Spectre on mobile. Android users will receive the necessary fixes and updates in waves – Google has already made these available for its own-brand Nexus devices, and we can expect to see security updates for Android devices from other manufacturers imminently. Samsung, Amazon, OnePlus and Huawei phones run variants of the Android OS. Windows 10 tablets and Windows Phone devices will shortly receive security fixes from Microsoft. Apple has emphasised that ‘there are no known exploits impacting customers at this time’. An Apple blog post published this week explains: ‘We continue to develop and test further mitigation’s within the operating system for the Spectre techniques, and will release them in upcoming updates of iOS, macOS, tvOS, and watchOS.’ Will the fixes cause slowdown? It’s been widely reported that the fixes required to address the Meltdown and Spectre security flaws could result in slowdown for devices. We’re conducting tests of affected laptops to confirm if this is the case. If you’ve shelled out for an expensive Mac in the hope of top speeds, you may be in luck. In a statement, Apple said: ‘Our testing with public benchmarks has shown that the changes in the December 2017 updates resulted in no measurable reduction in the performance of macOS and iOS.’ What do you need to do? Companies are battling to improve software security before hackers are able to take advantage of either the Spectre of Meltdown flaws. They’ve had a headstart, too, with chip manufacturers such as Intel being aware of the flaw for months, before making it publicly known this week. Keep an eye out for software updates on your tech devices. It’s important to install these promptly, be it on your smartphone, tablet, laptop or desktop. In its blog post, Apple notes that ‘many of these [security issues] require a malicious app to be loaded on your Mac or iOS device’. It’s important to only download apps and other software from known, trusted sources. You’re locked to using the App Store on iPads and iPhones, and Android users would be wise to stick to the Google Play Store only – these days, it’s vetted by Google to ensure malicious apps don’t sneak in. Amazon Fire tablet users must use the Amazon app store. Google has confirmed that its Chrome browser will be updated on January 23 to protect against exploitation. Meanwhile, Amazon Web Services, Google Cloud and Microsoft Azure have all been patched in light of this week’s security news. At the time of writing, we’ve seen no signs that any of these services have been compromised by hackers. We also suggest strengthening your computer’s defences with a Best Buy antivirus package.
