In early 2015, One of the examples came in the form of the effective power bug surfaced through the strings of characters or links capable of crashing messaging app and devices which phones would automatically crash and reboot. These problems faced by iPhone users which received a certain string of characters via text message. This week, a similar bug began making the rounds online.
According to BGR, First bug discovered by jailbreak developer Abraham Masri, the new bug (dubbed “chaiOS”) can cause crashing, freezing, resprings and more on both iOS and macOS. Masri’s warning in his tweet to “not use it for bad stuff” is not a joke — several people who couldn’t resist finding out what would happen are shouting about it in his replies.
The bug I released was to get @Apple's attention. It's just an html file.@Github always hosted jailbreaks (even .ipa files) that might've included malware. I don't understand why you'd ban my account.
Btw, I always report bugs before releasing them.

The Bug as chaiOS bug: Text the link below, it will freeze the recipient’s device, and possibly restart it. http://iabem97.github.io/chaiOS, tweeted Abraham Masri.
While some iphone users were unaffected by clicking the link because 9to5Mac was able to replicate the issues, such as crashing the Messages app on both the sender and the recipient’s devices. Going back into the thread in Messages that contained the link would cause the app to continually crash, which forced both parties to delete the thread.
Other issues included Safari crashing and “dramatic lag” in the Messages app on iOS and macOS. Masri didn’t explain what is causing the link to have such a dramatic effect, but this isn’t the first bug of its kind and likely won’t be the last. chaiOS appears to affect all of the latest public versions of iOS and macOS, as well as some beta versions. If you desperately want to see it in action, the link can be found in the embedded tweet below (but be prepared to face the consequences). And for heaven’s sake, don’t send it to an unsuspecting friend.
Apple has yet to issue any kind of response, but expect the bug to be addressed in a future update. That said, chaiOS doesn’t pose a serious or immediate threat to the stability of the affected device, so it might be a while.
