The new iPhone software update, iOS 18.4, could be more critical than is being talked about when it comes to security.

While there are lots of new features added in the latest release, out yesterday, what’s less talked about is the 62 security updates and fixes that roll out with this version. Some are quite serious.

Apple doesn’t make a big deal about these fixes as the plan is to keep them under the radar to stop attackers finding vulnerabilities or knowing when doors are closed to their attacks. Ultimately it’s a choice to help protect iPhone owners for as long as possible from the update rolling out.

Looking more closely at the iOS 18.4 update reveals there were some serous flaws that could leave current older software users at risk.

Some of the patches were found in WebKit, for Safari, and the Kernel at the heart of the iPhone operating system.

The fixes stops the possibility of a malicious app being able to attempt passcode entries on a locked device.

On websites there was the chance that a cross-site scripting attack could leave users vulnerable. This would allow attackers to inject malicious scripts right from trusted websites.

Why update to iOS 18.4 now?

Since all these patches are now publicly available it means attackers can see, even more clearly, the vulnerabilities in older versions. These are likely the devices that will be attacked now.

Since Apple has fixed more than 60 issues in one update, that means this is a big security shift – showing just how vulnerable older versions may be.

How to update to iOS 18.4 now

If you have an iPhone that’s the iPhone Xs or newer then this update applies to you and is available now.

To upgrade your software simply navigate to your Settings menu, then select the General tab and then Software Update. This will give you the option to download and install the iOS 18.4 update with a restart to let everything take effect. Then open up like you’re starting your brand shiny new iPhone.

Apple rarely updates CarPlay, but several changes are expected in the upcoming iOS 18.4 update. There’s truly something for everyone in the update.

Let’s begin with the fun news. In iOS 18.4, CarPlay will be integrating sports app functionality. This enhancement will enable drivers to view live sports scores and information on the road. Since this feature is available through an API, any sports app developer can implement it. Apple’s official Sports app will likely be the first, although that hasn't been confirmed.

Top Apple analyst suggests the iPhone Mini is truly extinct

Earlier this year, Apple released the iPhone 16E and put an end to the iPhone SE lineup. For those who had hopes the iPhone Mini might return, that doesn't seem likely either. In a Q&A session with Mark Gurman, the analyst said Apple doesn't have plans to bring the miniature version of its iconic lineup back anytime soon.

That's not exactly surprising. Apple basically killed the iPhone Mini lineup in 2023 when it launched the iPhone 14 Plus, leaving the iPhone 13 Mini as the last of its kind. With a 5.4-inch display, the iPhone 13 Mini wouldn't exactly fit in today's market of larger screens, but for users that preferred smaller phones, it was a godsend.
