A flaw discovered recently in Apple’s iPhone could allow nefarious people to hack SMS messages. According to AdaptiveMobile, the iPhone stands alone with this security hole. AdaptiveMobile tested the exploit in the iPhone and compared it to Android, BlackBery, Symbian, and Windows Mobile. All the other platforms remained secure in their treatment of SMS messages. The bug, unearthed by researcher pod2g, essentially allows hackers to spoof the reply-to number in a text message.
