Apple HomeKit bugs can plunge iOS devices into a death spiral

Apple HomeKit bugs can plunge iOS devices into a death spiral


You should always be careful about inviting strangers to your home.

This is the result of a new security investigation that discovered a vulnerability that could lock an iOS device to a spiral of freezes, crashes, and restarts when a user connects to a compromised Apple Home device.

Discovered by security researcher Trevor Spiniolas, this vulnerability could be exploited via the Apples HomeKit API, a software interface that allows iOS apps to control compatible smart home devices. If an attacker creates a HomeKit device with a very long name of about 500,000 characters, it will read the device name, enter a freeze and reboot cycle, and the iOS device that connects to it will stop responding. This can only be done by wiping and restoring. iOS device.

The most likely way to trigger an exploit is through a spoofed home network.

In addition, HomeKit device names are backed up to iCloud, so signing in to the same iCloud account on the restored device will trigger the crash again until the device owner turns off the option to sync home devices from iCloud. This cycle continues.

Attackers can compromise existing HomeKit-enabled devices, but exploits are most likely triggered by attackers creating spoofed home networks and tricking users through phishing emails. If you let me participate.

To prevent attacks, the main precaution for iOS users is to immediately reject invitations to unfamiliar home networks. In addition, iOS users currently using smart home devices will enter the Control Center and enter.[ホームコントロールの表示]You can protect yourself by disabling the setting. (This does not interfere with the use of your home device, but it limits the information you can access from the Control Center.)

Spiniolas published details on his personal website on January 1, 2022. He was previously credited by Apple for discovering a patched macOS Mojave vulnerability in 2019. As 14.7, Spiniolas said.

Spiniolas also accused Apple of being slow to respond to the initial disclosure made months before its public release. Researchers shared an email with The Verge, and Apple officials acknowledged the issue and apparently requested Spiniolas to refrain from publishing details until early 2022. A blog post detailing the vulnerability claims that Apple recognized the issue on August 10, 2021.

Not only is Apple’s lack of transparency frustrating for security researchers who often work for free, but it also reduces Apple’s accountability for security issues to millions of people who use Apple products in their daily lives. It poses a risk, Spiniolas writes.

Apple hadn’t responded to requests for comment by the time it was published.
