While iOS 11.4.1 update at a later stage.

Security researcher Sabri Haddouche on Saturday most recent iOS 12 beta, the security researcher says that it affects all the devices running iOS 9.0 and above.

The webpage is said to use all the available resources to cause a kernel panic on the system, causing the smartphone to power cycle off and on to prevent damage to the electronics. The code, based on Firefox on your iPhone or iPad.

Unlike some past iOS hacks that brought crashing cases through iMessage or other messaging apps, the latest case causes the sudden restart once you visit the specific webpage. This makes it less impactful. Also, it is worth noting here that the hack doesn't involve any data loss - it just crashes the system by putting much load on it. As it is only 15 lines of code, it can be planted into seemingly innocent websites, or sent via text message.

Nonetheless, Haddouche said that "anything that renders HTML on iOS is affected" through the flaw, as Twitter or could be given through an email or a WhatsApp message. Once you tap that link, your device will freeze for a second then restarts.

TechCrunch reports that Haddouche has already intimated Apple about the hack. It is, however, unclear whether the Cupertino giant will be able to fix the flaw in the iOS 12 update or through a new iOS 12 point release. Meanwhile, it is recommended to avoid tapping any unknown links on your iOS devices.
