A major security flaw that has existed in Apple’s iPhone since the device was first released in 2007 has been revealed by a well-known hacker. The iOS security researcher, known publicly only as “pod2g,” on Friday published details about the vulnerability, which affects all versions of iOS through to the latest beta release of iOS 6. According to pod2g’s report, the reply-to number that is displayed when an iPhone user views an SMS can easily be manipulated to display a number other than the one sending the message. Using a simple procedure, this exploit can be used by malicious attackers to send messages that appear to be from a trusted source — a bank, perhaps — but any replies to the SMS would be routed to a separate phone number without the sender’s knowledge.
