Similarly, the websites and servers you are accessing don’t get access to your IP address, location, or other identifying data – your traffic appears instead to be originating from the VPN server. The usual analogy is it’s like using a secret tunnel from your device to the VPN server. All they can see is that you are using a VPN. Your data is protected from an ISP, carrier, or hotspot operator. This is easy to do, and can be as simple as plugging a power-brick-size device into a coffee shop power outlet.Ī VPN instead sends your data in encrypted form to a secure server. This is when a bad actor creates a Wi-Fi hotspot that mimics a genuine one, but which routes all traffic through their system first, letting them log all of your data. When using public Wi-Fi hotspots, you’re also at risk from what are known as man-in-the-middle (MITM) attacks. That means that your ISP can see who you are and which sites and services you are accessing. They then forward it to the remote server. Normally, when you connect to a website or other server, your data is first sent to your ISP or mobile data carrier. His blog post about the issue is titled “ VPNs on iOS are a scam.” How VPNs (are supposed to) work Michael Horowitz’s actual words are a little blunter than our headline. This backs a previous report by ProtonVPN that a VPN vulnerability has been present on iOS devices since at least iOS 13.3.1, and that there is no 100% reliable way of ensuring that your data is being sent via the VPN …
Update: Apple does appear to have introduced an (optional) fix for this as of iOS 14, but questions remain – see update at end.Ī well-known security researcher says that iOS VPN apps (virtual private networks) are broken, due to a flaw that he claims Apple has known about for at least two and a half years.
