iOS 14 has been announced with some amazing new features for iMessage, including more options for group conversations, built-in answers and more. However, there is also a major change in iMessage that Apple has not mentioned so far. The company has adopted a new security system called “BlastDoor”, which is basically a sandbox mode that protects the Messages app from the rest of iOS.
As reported by ZDNet, this new iOS 14 security feature was discovered by Samuel Groß, a security researcher working with Google’s Project Zero. All iOS apps already work in sandbox mode, but BlastDoor adds extra protection to iMessage.
Its role is to take incoming messages and unpack and process their content in a secure and isolated environment, where any malicious code hidden in a message can not interact or harm the underlying operating system or with user data do not pick up.
According to the security researcher, iMessage has been the target of multiple attacks in the past, as several researchers pointed out that Apple’s messaging service “did a poor job of disinfecting incoming user data.” This allowed hackers to take control of an iPhone by simply sending an SMS or a photo to the device.
Groß told the report that he believes Apple has finally decided to listen to community feedback to improve iMessage security, which led to BlastDoor being implemented with iOS 14. ‘It’s great to see that Apple is setting aside resources for these kinds of big refactors. to improve the safety of end users, ”said the researcher.
More information about the changes in iMessage’s security system can be found in Google’s official Project Zero blog.
