Mobile security company Skycure revealed details about an iOS 8 vulnerability that could potentially allow an attacker to put all nearby iOS devices in an unusable state.

The company calls this bug the "No iOS Zone."

To exploit the vulnerability, an attacker would have to configure a wireless router in a specific way, and then use it to start an unprotected wireless network. Once an iOS device connects to the network, it crashes and — under certain conditions — keeps on crashing after rebooting (as seen in the video, below). Once under attack, the only way to fix the issue is to physically move away from the location of the offending wireless network.

"By generating a specially crafted SSL certificate, attackers can regenerate a bug, and cause apps that perform SSL communication to crash at will," Skycure CTO Yair Amit wrote in a blog post. "As SSL is a security best practice, and is utilized in almost all apps in the Apple app store, the attack surface is very wide."

For tech-savvy iOS users, the fix might seem simple: Set your device so that it doesn't automatically connect to unprotected networks. However, in 2013, Skycure discovered another vulnerability called WiFiGate, which makes it possible for an attacker to force a mobile device to automatically connect to a Wi-Fi network. By combining these two vulnerabilities, an attacker could create a scenario in which all iOS devices in an area immediately become useless, regardless of their wireless configuration.

While Skycure's researchers said they haven't yet seen exploits using the No iOS Zone vulnerability, users should still be careful when connecting to Wi-Fi hotspots.

"Smartphone users should take care with how they associate to Wi-Fi, especially unsecured, open access points. Attackers can carry out more subtle attacks, such as DNS poisoning and DNS hijacking, which can expose private, personally identifying information," Tod Beardsley, engineering manager at security firm Rapid7, told Mashable in a statement.

According to Skycure CTO Amit, the company has yet not publicly provided all the technical details of this vulnerability to protect iOS users from potential attacks, and is currently working with Apple on a fix. However, the latest version of iOS, 8.3, does alleviate "some" of the described issues, so users are advised to upgrade to that version as soon as possible.
