It's worth noting however that both recent Windows and Mac OSes at least detect captive portals automatically and show the login page themselves, making elaborate and insecure hacks like that unnecessary.
- jimeh 12y agoThat is true, but everyone aren't running even recent-ish OSs. Also having relied on BT Wifi for about 2 weeks recently, I can definitely confirm that OSX's detection doesn't always work. About 80% of time, it's fine, the other 20% it's google for "asdf" and get redirected. Also, BT Wifi tends to log you out every 20 minutes to 6 hours seemingly by random, forcing you login with your credentials again, and this need to re-login is something that OSX never detected.
- andreasvc 12y agoIsn't that a security hazard? The mechanism of these captive portals is literally a MITM attack, and I don't see how to distinguish a benevolent from a malevolent use of it.
