More precisely, a MitM site can send someone else’s certificate, but it almost certainly can’t produce any cryptographic “proof” that it has possession of the private key that the certificate is meant to validate. You can then fetch the content they expect from the real site (you are the MitM, after all), feed it back to them with tweaks, modifications and malware, and they may be none the wiser.īut if they visit then it’s much harder to trick them, because your MitM site can’t provide the HTTPS certificate that the official site can.

If you run a dodgy wireless access point, for example, you can trick users who think they are visiting, say, into visting a fake site of your choice, because you can redirect their network traffic. MiTM attacks against unencrypted websites are fairly easy.

This issue was addressed by restoring missing validation steps.Īpple didn’t say exactly what it meant by “a privileged network position,” or by “the authenticity of the connection,” but the smart money – and my own – was on what’s known as a Man-in-the-Middle attack, or a MitM. Impact: An attacker with a privileged network position may capture or modify data in sessions protected by SSL/TLSĭescription: Secure Transport failed to validate the authenticity of the connection. The update was a patch to protect iPhones, iPads and iPods against what Apple described as a “data security” problem: At the end of last week, Apple published iOS 7.0.6, a security update for its mobile devices.
