How to keep your device protected against Meltdown and Spectre

Panic over the security holes named ‘Meltdown’ and ‘Spectre’ that have the potential to affect devices powered by Intel, AMD or AMD processors has been widespread. These chips speed up your device’s performance by assuming what you’ll do next, based on previous usage, to execute the action in advance. The ‘hole’ is that hackers could use this common feature to steal private data such as passwords.

These security issues apply to all modern processors and unfortunately affect nearly all computing devices and operating systems. The good news? Apple, Google, Intel and Microsoft have confirmed that there have been no known cases of either Meltdown or Spectre impacting customers.

“All Mac systems and iOS devices are affected, but there are no known exploits impacting customers at this time.” – Apple

 “We have not received any information to indicate that these vulnerabilities has been used to attack our customers.” – Microsoft

Since learning of the security issues, industry leaders have been working hard to overcome the potential loopholes. For customer protection, information of Meltdown and Spectre was kept under wraps until preventative measures were available to avoid giving hackers a roadmap. So far, Intel has issued updates for nearly 90% of processor products introduced within the past five years, but a timetable for older devices is yet to be confirmed.

Apple has released a software update to help protect users from Spectre and Meltdown. We highly recommend you update your devices as soon as possible. Here’s how…

How to stay protected – Android users

On January 5th 2018, Google issued an update to protect Android devices. All Google-branded phones should have automatically downloaded the update so you just need to install it. For other Android devices, head to Settings. Scroll to the bottom of the menu and tap ‘About device‘ > ‘System updates‘ > ‘Check for update‘ > Tap ‘OK‘ if asked to confirm > Wait for your device to check for updates > Tap ‘Download‘ or ‘Yes‘ if an update is available.

Google Chrome

The patch for Chrome will be installed on January 23rd and some Chromebooks had a mitigation in its OS 63, released in December. If you do not want to wait, an experimental feature from Google called Site Isolation can help in the meantime. This feature makes it harder for malicious websites to access data from other websites you are looking at. To use this feature on Windows, Mac, Linux, Chrome OS or Android copy and paste chrome://flags/#enable-site-per-process into the URL in Chrome. Click ‘Strict Site Isolation‘ and then press ‘Enable‘. Save your work and then press ‘Relaunch now‘.

Microsoft Windows 10

There is already a patch available for Windows 10 which will automatically be applied, a patch for older operating systems will follow shortly.

Cloud Services

Major cloud services aimed at business customers, including Amazon Web Services, Google Cloud Platform and Microsoft Azure have already been patched.
