WHAT HAPPENS IF YOU CLICK ON CRASHSAFARI.COM? 

The page includes a header title (which you'll never actually see because the browser crashes) and a small piece of JavaScript. 

The JavaScript calls the HTML5 History API thousands of times in a loop, essentially causing Safari to freeze. 

The memory will overload and the iPhone will overheat, which causes it to shut down completely.

Depending on how the website is opened, it will either crash the current app, the Safari browser, or the whole of system. 

It will reboot on its own and the prank doesn't have the ability to install malware or pose any security threats.

Who says he stumbled on the bug and made the site as a joke.

The link is being passed around on Twitter, as users are sharing it in tweets with the hopes their followers would in click it.

Twitter has sent out an announcement warning users of the hack, but has said 'it has no serious threats'.

The social media network hopes this will stop the prank from making too many rounds, but the link can be messaged privately - so beware, reported TechCrunch.

The Chief researcher officer at security firm F-Secure, Mikko Hypponen, first identified the prank and believes it is 'an identical site at crashchrome.com actually exploit browsers' history feature to kill them on command'.

'The problem is that it creates thousands of history entries,' Hypponen told Wired, citing a thread in a Chrome developer's forum where the bug was reported in 2014.

'It takes longer to maintain the list than it takes new entries to come in.'

'It becomes too much, and it tanks.'

Mac, Windows and Androids are also seeing a problem if they click on the link.

Although the system doesn't completely shut down, the browser will become sluggish and force users to close it.

Seeing you iPhone screen go black then reboot is enough for anyone to panic, but this prank isn't programmed to install malware on devices.

According to 9TO5Mac, the hack has been reported to work on the latest versions of Apple's operating system, iOS 9.2.1 and OS X 10.11.3 and some of the beta seeds.

Apple is working on fixing the issue in future updates, but there is no rush because the system isn't damaged or poses a security risk.
