Earlier this week, a software developer on Twitter shared a link that is capable of blocking an iPhone or Mac when it is sent through the Messaging application. Called "chaiOS", the error works in a manner similar to the "Power of Attorney" error of 2015, which involved sending a text string to another iPhone user that would cause the recipient's phone to be blocked and rebooted. ChaiOS is more of a nuisance than a serious security flaw, but in any case, it will not last much longer.
On Thursday, just two days after the malware initially spread on Twitter, Apple told BuzzFeed that a fix comes in a software update next week. No more details were shared, but presumably the iOS and MacOS devices will receive the update, since both can be affected by the text string in the Messages application.
Unless your contact list is full of trolls, you probably will never have to deal with chaiOS before Apple takes care of that. In fact, the original link has already been removed by GitHub (which is where it originally stayed), but the code contained in it has probably been copied by others and hosted elsewhere.
"My intention is not to do bad things," Abraham Masri told BuzzFeed . "My main goal was to approach Apple and say:" Hey, you've been ignoring my bug reports. "I always report the error before launching something.
At this time of next week, the update will have gone out, but if you receive the error in the meantime, do what you can to remove the text thread that contains it. That could be a challenge, since the Messages application will be blocked repeatedly for some users, but it is the only option other than a factory reset. If it comes to that, back up your data first.
