Researchers Zane Lackey and Luis Miras plan to show how they were able to spoof SMS and MMS messages and falsify the signaling data that underlies these messages at this week's Black Hat conference, reports Computerworld.
According to a source, the talk will detail security flaws in the way some mobile networks communicate with the devices on the network. In theory, an attack could redirect a phone's Web browser to a malicious server or change voicemail notifications. The source says the attack works on the GSM -based networks but not on CDMA.
Researcher Charlie Miller also is set to discuss an SMS bug. He claims to have discovered a flaw in the way iPhones handle text messages received via SMS that could allow an attacker to remotely install and run unsigned software code on the phone.
