iPhone Virus: How Do I Protect Myself?

By Sean Ryan

So youve heard about the iPhone virus? It seems like everyone has by now. But the pressing question is: Is there a virus out there? The answer to that is yes"It was developed over a two and a half week period by Charlie Miller, principal analyst at Independent Security Evaluators. That begs the question: If Charlie did it, when will a malicious virus infect iPhone users and what can they do to protect themselves?

Mr. Miller learned that through the use of a malformed SMS message (a simple text message), the iPhone becomes confused and, in this confused state, it will process data within the message improperly, which would allow the iPhone and all data stored in it to become vulnerable to a remote hijacking. Through this window, a remote hijacker could gain complete control over your phone. They could watch you type text messages, input bank passwords, type emails, and so on. Not good.

If a bad guy were to write such code or something similar, millions of iPhones would be at risk (this also includes Android phones and those operating with Windows Mobile too). This gaping hole in the armor could use the remote command to install malware on the iPhone, which could theoretically turn your camera on and start recording sound. Imagine all the ways a remote hijacker could use that tool. Pretty frightening stuff.

What are iPhone users supposed to do? Right now there is not much they can do except encourage the manufacturer to fix the issue. But in the long run, due to the exponential growth of iPhones and other smartphones and their extraordinary capabilities, the threat to the information held within them will only increase. The best thing to do is protect your device. Keep up with potential threats and make sure you have taken all possible precautions in protecting your iPhone. Hopefully this iPhone virus buzz will turn out to be nothing serious. But that doesn't mean you shouldn't be proactive.
