When Apple urges you to update your iPhone, iPad, Mac or iPod Touch, you should do it. If you have one of those devices, you recently got a notification to update your device to iOS 10.3.3.
Apple says the update contains a bug fix to a security flaw that could allow a hacker to not only access your device, but to actually take control of it.
The security risk deals with the ability to use Wi-Fi. According to the blog 9to5 Mac, a user discovered the hole and reported it to Apple.
If you actually look at the description of the update by Apple, it shows that it’s possible for an attacker within range to execute arbitrary code on the Wi-Fi chip.
The update was made available this week, but many iPhone users may have either not noticed it or brushed it off.
To see if your device needs to install the update, just look in the settings app. If there’s a red 1, you have the update available. It takes a few minutes to install the update, and you should be on a secure Wi-Fi network to do it.
While we’re at it, I know some people will either not notice updates in general or just put off them off until later. When you see an update become available, read the description. If it contains a bug fix or another security update, go ahead and install it as soon as possible. While many Apple users believe their device isn’t susceptible to hackers, that’s no longer the case. Hackers will go where there are large numbers of possible victims, and they’ll search for any vulnerability they can use.
