Watch out Apple users! Link crashing Safari

Following the fun users had with the “effective power” iPhone text message bug, people have been sending a link to users of Apple’s Safari browser that will crash their iPhones or Macs.

The link, which is simply, overloads the default browser with a self-generating text string which populates the address bar. After about 20 seconds or so it will force an iPhone to reboot, while significantly heating up as the smartphone tries to handle the code of the site.

A similar thing happens on iPads, which also has Safari, while even Android devices running Chrome heat up and become sluggish. Rebooting the iPhone or quitting Chrome on an Android device clears the problem.

Desktop and laptop computers are also affected to a lesser degree depending on how much processing power they contain. The site will cause Safari on a Mac to crash. Chrome on a Mac and PC also becomes bogged down.

The code of the website appears to generate an ever-increasingly long string of characters, which becomes harder and harder for the browser to load, likely resulting in a memory issue and forcing the reboot of the device.

As with the effective power text message bug, users have started sending the link disguised by URL shorteners with tempting text to get iPhone users to click on the link and crash their smartphones.
For the immediate future, iPhone users should be very careful about which shortened or obfuscated links they click on, should they be forced into rebooting their smartphone. Should the worst happen, it appears that smartphones will behave normally after a reboot.
