Windows Phone SMS attack - YouTube

Attackers can send a maliciously-crafted SMS to a Windows Phone, causing it to reboot and disable messaging functionality. "The flaw appears to affect other aspects of the Windows Phone operating system too," reported WinRumors.

"If a user has pinned a friend as a live tile on their device and the friend posts a particular message on Facebook then the live tile will update and causes the device to lock up." WinRumors and Khaled Salameh, the researcher who discovered the vulnerability, are in the process of disclosing the flaw to Microsoft.

"At this stage there doesn't appear to be a workaround to fix the messaging hub apart from hard resetting and wiping the device."
