Apple responds to SMS vulnerability concerns, suggests using iMessage
Apple has responded to questions raised by pod2g earlier this week over an SMS vulnerability he discovered in the latest iOS 6 beta 4. The SMS vulnerability could allow someone to abuse the protocol for SMS in order to spoof or send fake text messages. The exploit has been an issue since the incarnation of iOS and is still present in iOS 6 beta 4. Apple issued a statement to The Loop which explains that the problem was not an iPhone specific problem as first thought but down to the SMS protocol used by all phones.
“Apple takes security very seriously. When using iMessage instead of SMS, addresses are verified which protects against these kinds of spoofing attacks,” an Apple representative told The Loop. “One of the limitations of SMS is that it allows messages to be sent with spoofed addresses to any phone, so we urge customers to be extremely careful if they’re directed to an unknown website or address over SMS.”
So there you have it, the problem is not with just the iPhone but it is an SMS problem for every phone. The idea of using iMessage for all messaging on your iPhone sounds like a great one. Unfortunately, from my experience it is not exactly reliable; some messages never reach their destination or the iMessage servers are down when I want to use it. The other problem of course is that if the recipient doesn’t have an iPhone then SMS is your only option.
