The crux of the issue is that when a consumer prompts a VPN on an iPhone or iPad, the system doesn’t disconnect all Internet connections after which restart them within the VPN tunnel. Because of this conduct, whereas a VPN could route some connections by its servers to cover the consumer’s actual IP tackle, connections exterior the tunnel could leak the system’s IP tackle or different information.

ProtonVPN advertised subject and reported it to Apple in 2020, however Horowitz’s current checks present it stays unresolved within the newest variations of iOS and iPadOS (15.6). Horowitz discovered that the issue impacts ProtonVPN, WireGuard, Windscribe and others, exhibiting that the vulnerability is expounded to iOS itself. Several workarounds have been proposed by Apple and Proton, however Horowitz’s checks present that none of them are dependable.

One resolution is to make use of Apple’s Always-on VPN characteristic, which ensures that the VPN tunnel is all the time energetic earlier than exterior connections may be began. However, this requires deployment system administration is a fancy course of that’s past the attain of most customers.

In late 2020, Apple added to VPN for iOS the power to activate a kill swap to cease all connections if the VPN fails. However, Horowitz’s checks nonetheless confirmed non-VPN connections going by after enabling this characteristic.

Proton recommended turning on Airplane Mode after activating the VPN to disable all system connections after which turning off Airplane Mode with VPN nonetheless enabled, which ought to restart connections contained in the tunnel. Airplane mode could not cease all earlier connections, nevertheless, as customers can handle Wi-Fi settings independently of it, which might confuse the method.

Ultimately, Horowitz advises towards trusting any VPN on Apple iOS units. Instead, customers could wish to use a VPN from a router to guard all the community in case information is leaked from particular person units. A secondary router devoted to VPN connections is right.
