Man-in-the-Middle Attack on MySpace with Cain
Slimjim100 writes "Last year at ChicagoCon 2007, Brian Wilson gave a great talk entitled "Cain & Abel: Windows Can Hack, Too!" Although the presentation and audio recording of the talk can be downloaded from the ChicagoCon site at Library, I had totally forgotten to publish his videos. Just in case things didn't go as planned during the live event or his laptop crapped out on him, Brian made a video of the MITM attack he demonstrated using Cain. You get to see how Myspace and other social networking sites are not designed with security in mind."
Hell, I remember scriptkiddying passwords out of .pwl files in '00. These apps have been around for a long time.
The point isn't that you'd get a pop-up when everything's going right - you'd get a pop-up when someone's attempting the man-in-the middle attack. And if the users aren't savvy, or assume as the OP said that the certificate has just expired, they're going to click through anyway.
