The Deathray: A simple way for an untrusted site to freeze a Mac

Amazing!

I encountered the same type of death freeze when trying (and failing) to run models in browser tabs, but didn't spend much time trying to understand how severe it is.

Hope they don't disable WebGPU...

Zero impact on iOS 27.

Still impacts macOS 27 release candidate.

Remember when that unicode string nuked iOS 7 and you could set it as your SSID to get them stuck in a loop? good times.

Could be a useful way to force user-interaction-gated flows. A "your computer is infected, click this button in 10 seconds or it will crash" type button which, at this point, most modestly-knowledgeable users would know not to click. However, after seeing their computer actually crash when the countdown hits 0, perhaps they would be more inclined to click "allow" on whatever prompt follows when they see it again.

Of course, plenty of other uses. Disable your adblocker or we crash your computer. Watch the whole ad or we crash your computer. Click the follow button or we crash your computer.

Maybe I'm crazy, but "crash your computer" as a building block seems powerful enough to be a security issue. Is denial of service not a security thing anymore?
