Updating your iPhones, iPads and iPod touches
to iOS 10.2.1 might be the most secure thing you do today. That’s
because the new update includes a wide range of security fixes that
protects against very bad attacks.
Over a dozen
vulnerabilities are listed in the 10.2.1 update, including
two where a malicious app can execute code within the kernel, which
means it can take complete control of your iOS device. Seven
vulnerabilities are listed for WebKit, the engine that powers
mobile Safari, including two fixes that list how rogue websites can
execute code on the impacted iOS device.
If you own an iOS device, grab the update to iOS 10.2.1
by going to the Settings app, then General, Software Update. You
must be plugged into a power source for your device to update, and
as always, we recommend you back up your device before
updating.
Apple has also released updates for watchOS, macOS and
tvOS, which are focused on bug fixes and performance
improvements.
