PRESS RELEASE

SAN FRANCISCO, CA - July 31, 2009- iPhones are the most vulnerable mobile devices to attacks from hackers, according to a survey of security professionals attending the Black Hat USA conference held this week in Las Vegas.

The survey was conducted by nCircle, the leading provider of agentless security and compliance audit solutions.

The full survey results are:

What mobile devices will be most vulnerable to attack for the remainder of 2009?

-Google / Android Phone (13) 14% -iPhone (55) 56% -Blackberry (7) 8% -Nokia OS (5) 5% -Other (14) 15%

According to Andrew Storms of nCircle, "The iPhone is really a security triple threat. Its enormous commercial success and huge number of users -- and the exponentially increasing number of available apps -- mean more and more information is being stored on the phone. Adding to the threat, security researchers know a lot about the OS, even though Apple is trying to keep the system closed.

"Unfortunately, it looks like the security problems with iPhone will continue to grow until Apple makes security a higher priority," continued Storms. "If there is a silver lining for iPhone users, it's that all of the security research attention it is getting could eventually turn the iPhone into one of the most secure mobile platforms."
