Virus experts warn next big threat is to mobile phones

Virus experts are warning that the next big security threat is on mobile phones and that the attacks have begun in earnest.

For months, security researchers have been tracking how hackers were trying to take their exploits to a new platform and infect smartphones with malware that could remotely control the devices.

Earlier this week, Symantec released a report about the spread of an infected app called "Steamy Windows" on Google's Android platform. The simple but popular app makes it look like your screen is covered with steam, which can be cleared off with finger swipes. Unknown hackers created a copycat version of the app, secretly loaded it with malicious commands, and released it to the web on unofficial app download sites.
