If you’ve been keeping up with iOS news, you probably already know that the stable, public version of iOS 10.3.3 has been released on July 19. It doesn’t really bring anything new with it, which isn’t surprising since iOS 11 is just around the corner and is expected to come with a range of new and exciting features. However, what iOS 10.3.3 does have is a security patch for a critical vulnerability.
Known as Broadpwn, this vulnerability stems from the Broadcom BCM43xx Wi-Fi chipsets, which have been used in all iPhone models starting from iPhone 5 and above. Through this security issue, any hacker within Wi-Fi range of an iOS device can execute memory-corruption exploits and remotely gain total control of the device.
Broadpwn has scored 9.8 out of 10 on the U.S. National Institute of Standards and Technology severity scale. This means that it has incredibly high potential of destroying the safety and security of iOS users and putting their personal information, financial data, and important files at risk.
The vulnerability was discovered by security researcher Nitay Artenstein, who works at Exodus Intelligence and has brought the security flaw to Google’s attention. As a result, Android devices have received a security patch for it earlier this month. Artenstein is scheduled to detail exactly how Broadpwn can affect iOS devices at Black Hat USA 2017, which will take place on July 22 to 27.
Aside from affecting the iPhone 5 and later models, Broadpwn also affects the sixth-gen iPod Touch as well as the fourth-gen iPad and later models.
Those who own these iOS devices are advised to update to iOS 10.3.3 as soon as possible to avoid getting targeted by hackers through Broadpwn. However, people in the jailbreaking community have been hesitant to update to the latest iOS firmware. This isn’t really surprising since updating to iOS 10.3.3 means losing the chance to be eligible for jailbreaking tools that are made for earlier versions of iOS 10.
Several jailbreakers have been asking for Cydia developers to create a patch for Broadpwn so they can protect their devices while still enjoying jailbreak tweaks. Others, meanwhile, are sticking to their guns, stating that the security risk is low since hackers would have to be physically near them to carry out attacks.
