A problem with the iPhone's Wi-Fi connection could have let hackers take over people's devices and crash them, the company has revealed in its latest update. Apple has released a security update that fixes a problem with the Wi-Fi chip in the iPhone, which could have let cyber criminals access a phone while it was searching for a connection. Using the problem, hackers could have found phones with Wi-Fi switched on, remotely taken over the chip that powers Wi-Fi, and crashed the device.Android devices were also affected by the problem, called the Broadpwn exploit, and Google issued an update at the beginning of the month. Described as a "critical" flaw it affected devices from numerous brands including Samsung and HTC. Apple released a fix for the Broadpwn exploit in an update that patches an additional 46 flaws in iOS 10. They include a bugs in Messages, Safari, Notifications and Contacts, as well as a way to take over devices using WebKit. Users are advised to apply the update in order to keep their devices secure from would-be cyber criminals. The Wi-Fi problem was discovered by Nitay Artenstein, a security researcher at Exodus Intelligence. Other key problems Apple has now fixed were discovered by Google's Project Zero, independent researchers and Apple.
Apple regularly releases updates that fix security bugs before they're exploited. Earlier this year it issued an urgent fix for an arsenal of spying bugs revealed by Wikileaks in the Vault 7 files. The iPhone giant advises users to always download the latest software in order to keep their devices secure. Other tips include having a strong, unique passcode, turn off notifications and disable Siri for when the handset is locked. The iOS 10.3.3 update comes just months before the company releases iOS 11, the software designed for the iPhone 8. The latest software includes phone-to-phone Apple Pay, a redesigned control and notifications centre, and a "do not disturb while driving" mode.
