IOS 14 has been announced with some great new features for iMessage, including more options for group conversations, online responses and more. However, there is also an important 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 application from the rest of iOS.
As reported by ZDNet, this new iOS 14 security feature was discovered by Samuel Groß, a security researcher who works with Google’s Project Zero. All iOS apps already work in sandbox mode by default, but BlastDoor adds an extra layer of protection to iMessage.
Its function is to take incoming messages, unpack and process their content in a secure and isolated environment, where any malicious code hidden within a message cannot interact with or damage the underlying operating system or recover user data.
According to the security researcher, iMessage has been the target of several attacks in the past, as several researchers pointed out that Apple’s messaging service was “doing a terrible job of cleaning up user input data.” These exploits allowed hackers to take control of an iPhone just by sending a text or photo message to the device.
Groß told the report that he believes Apple has finally decided to listen to feedback from the community to improve the security of iMessage, which has resulted in the implementation of BlastDoor with iOS 14. the safety of end users ”, said the researcher.
More details on changes to the iMessage security system can be found on Google’s official Project Zero blog.
