A new CSS based attack can now crash your iPhone and force it to restart. This attack is equally affecting iPad while Mac users can face a brief freeze on their Mac. We are not saying this, a security researcher by the Twitter username @pwnsdx discovered it. This is all done by using a few lines of CSS code. This exploit uses basic webpage written with few lines of HTML and CSS codes. The codes are also not that complicated.

These codes try to apply something called backdrop-filter to a series of nested properties known as div. This property is relatively new, and it works by color shifting or blurring our images that are inside a div element. It requires a lot of processing power that we suspect Apple cannot handle. Apple by default uses Apple web rendering engine WebKit to render all the web pages. We suspect that nesting lot of elements under the backdrop-filter may have been causing lots of stress for the GPU and kernel and forcing the device to restart to avoid damaging hardware.
The bug seems to attack both the iPhone and iPad similarly by crashing the phone and restarting. While Mac users are not facing restart Mac, but it does freeze the Mac for few minutes.
After the getting the report, we tried to test and found that our phone is also vulnerable to the bug. This bug can sound harmless, but it is not. Anyone online via Twitter and Facebook sends you a link with those codes and make your device restart on the middle of something.
Few users also reported the same bunch of codes could even crash Apple Watches as well. You can see in this twitter video posted by someone by the username @Sonikku_a2
Also looks like watchOS 5 is susceptible. pic.twitter.com/Mam8uTyuye

At least a good news is that this bug cannot be used to run and execute malicious codes. That means how annoying this bug can be you can at least be sure that no one has installed some spooky malware on to your device to steal your data.
How The Internet Reacting this Bug
Every time there is a new bug Internet uses it’s in the most creative way possible. One of the users said that finally, they could use this bug to command Siri to restart the phone while another user shared a screenshot where he is using the same link to reboot the iPhone.

This is hilarious.
Apple and Bugs
Apple has an excellent track record of fixing bugs, but every once in a while you see bugs that are hilarious. One of them was a Telugu character that causes crashing iPhones, iPads, and Macs. This was back in February in 2018. Apple then since fixed this issue. You can see in the video down below.
The internet was exploded with people pranking other Apple product users by sending them the character and making them restart the phone. There was some funny meme as well on this same bug.
So what do you think about this new bug? Have you also faced this bug on your iPhone or Mac? We are eager to hear your funny story.
