Android Phones are Risk To Wipeout Attack

Cellphones using Google's Android operating system are at risk of being disabled or wiped clean of their data, including contacts, music and photos, because of a security flaw that was discovered several months ago but went unnoticed until now.
Opening a link to a website or a mobile application embedded with malicious code can trigger an attack capable of destroying the memory card in Android-equipped handsets made by Samsung, HTC, Motorola and Sony Ericsson, rendering the devices useless, computer security researcher Ravi Borgaonkar wrote in a blog post Friday. Another code that can erase a user's data by performing a factory reset of the device appears to target only the newly released and top selling Galaxy S III and other Samsung phones, he wrote.

The bug works by taking advantage of functions in phones that allow them to dial a telephone number directly from a web browser. That convenience comes with risk, however. A hacker, or anyone with ill intent, can create a website or an app with codes that instruct the phones linking to those numbers to execute commands automatically, such as a full factory reset.
The phone's memory card, known as a subscriber identity module, or SIM, can be destroyed remotely in the same way, Borgaonkar said. "Vulnerability in Android can be exploited to kill the SIM card permanently by clicking a single click."
