iPhone Bug Freezes Your Phone With Just One Link

iPhone Bug Freezes Your Phone With Just One Link

The chaiOS bug can freeze or restart your phone without even having to click the link.

Imagine receiving a text from someone, you open the thread and see the text is actually a link. Before you even click on the link, your phone freezes up or restarts, throwing you into a panic. Unfortunately, this can happen. It is the exact bug software developer Abraham Masri found in iPhones this past week.

Masri announced the bug, which he aptly named "chaiOS," on his Twitter account and explain that it exploits the fact that iMessages preloads any links to webpages so it can show users a preview of the page. In an interview with Buzzfeed News, Masri explained that he create a webpage hosed on GitHub and stuffed its metadata with hundreds of thousands of unnecessary characters causing your phone to crash when trying to load all of the unexpected information, sometimes taking the entire operating system down with it.

Initially, Masri had posted a link that used the chaiOS in a Tweet on his account, but the page, and a few others that mirror the bug, has since been taken down by the host site. Masri said he isn't going to re-upload the bug, saying he only released it to "get Apple's attention."

Apple has announced they will release a fix for the bug next week.

  • From Surveillance to Intelligence

    Years ago, it would have been significantly more expensive to run an analytic like that — requiring a custom-built solution with burdensome infrastructure demands — but modern edge devices have made it accessible to everyone. It also saves time, which is a critical factor if a missing child is involved. Video compression technology has played a critical role as well. Over the years, significant advancements have been made in video coding standards — including H.263, MPEG formats, and H.264—alongside compression optimization technologies developed by IP video manufacturers to improve efficiency without sacrificing quality. The open-source AV1 codec developed by the Alliance for Open Media—a consortium including Google, Netflix, Microsoft, Amazon and others — is already the preferred decoder for cloud-based applications, and is quickly becoming the standard for video compression of all types.
