Security iOS VPNs have leaked traffic for more than 2 years, researcher claims

A security researcher says that Apple's iOS devices don't fully route all network traffic through VPNs as a user might expect, a potential security issue the device maker has known about for years.

Michael Horowitz, a longtime computer security blogger and researcher, puts it plainly—if contentiously—in a continually updated blog post. "VPNs on iOS are broken," he says.

Any third-party VPN seems to work at first, giving the device a new IP address, DNS servers, and a tunnel for new traffic, Horowitz writes. But sessions and connections established before a VPN is activated do not terminate and, in Horowitz's findings with advanced router logging, can still send data outside the VPN tunnel while it's active.
