If you use an older Apple device you should urgently download the latest update as you may be vulnerable to hackers.
The American tech giant has identified a number of bugs, including one which has a 'zero-day' rating. This rating means that hackers are aware of the flaw and are actively exploiting it.
Those with affected devices, which includes the iPhone 7 and iPhone SE, should immediately go to settings and download an update called iOS 15.7.4, reports the Mirror.
