Keeping your information and details safe and secure is essential, and its one Apple is stressing in a new update to anyone with an iPhone.
The tech manufacturer, which also produces the iPad and Apple Watch, regularly updates people with its devices on how they can stay safe amid hacking worries.
Those with an iPhone need to be aware of threats to them, like the hidden ability to make deep fakes of you, an issue that was first found by cyber security company Group-IB.

Those using Apple's iOS rival, Android, aren't exempt from the threats either, with an urgent warning issued to everyone who uses WhatsApp on phones with an Android OS.
Now, Apple has told iPhone users how 'important' it is to upgrade their iOS to the latest patch.
It follows a number of bug and security worries.
The update was made available over the weekend and comes just weeks after iOS 17.4 dropped in the European Union.
In its release notes, Apple said: "This update provides important bug fixes and security updates and is recommended for all users."
Devices that can install iOS 17.4.1 are the iPhone XS and later; iPad Pro 12.9-inch 2nd generation and later; iPad Pro 10.5-inch; iPad Pro 11-inch 1st generation and later; iPad Air 3rd generation and later; iPad 6th generation and later; and iPad mini 5th generation and later.
Right now, Apple is yet to release details of what 17.4.1 actually is. It simply says on its website that 'details are coming soon'.
Apple says: "For the protection of our customers, Apple doesn't disclose, discuss, or confirm security issues until an investigation has occurred and patches or releases are generally available."
With that in mind, it could well be the case that Apple is currently patching the same security problems on its other products and as such, doesn't want to speak publicly about the vulnerabilities before they are patched on Apple's end.
But what we do know is that people reported bugs with the 17.4 update, such as battery life being drained quicker than before. Others reported issues with Apple Music and AirPods not syncing with phones.
To update your iPhone's iOS, go to Settings and then General.
From there, you should select Software Update and see what update is available for your device.
There's a few options to choose from; Update Now or Update Tonight. Both will depend on your battery life.
