Receiving this malicious link through iMessage can freeze your iPhone, iPad and Mac
A malicious link, dubbed “chaiOS”, is spreading through iMessage, causing the Messages app to break and freeze on iPhone, iPad and Mac devices.
Users who receive the chaiOS link will be effected from the moment they receive the message, with the iOS link preview feature opening a snippet of the webpage meaning a user will be effected even if they don’t press the link themselves.
Luckily, it appears that the bug can be removed by force closing the Messages app on either your iOS or macOS device and then reopening and deleting the conversation thread, bringing back all functionality to a users device.
Apple hasn’t commented on the issue as of yet, however it’s likely the company will rollout a software update very soon to patch the issue.
