Researchers at SMobile Systems, a cell phone monitoring and security firm, released a report last week detailing the ease with which online banking information, email logons, and various other sensitive personal data could be stolen from smart phones on public wireless networks.
The technique uses a widely available program called SSLstrip to insinuate itself between the mobile device and the wireless network server, allowing a hacker to monitor all data sent between the two machines. In public tests, the team from SMobile was able to view password information for numerous accounts accessed by the four smart phones that they tested, which included the iPhone 3GS, Nokia N95, Android G1, and HTC Tilt.
The report says that the ease of access to such sensitive data is dependent on two factors. First, unsecured Wi-Fi networks, like those present in airports and coffee shops, are highly vulnerable to unauthorized access. Second, even the most advanced mobile wireless devices are frequently without even rudimentary security programs.
Some experts recommend refraining from checking important information – like personal email or online bank accounts – from unsecured connections or wireless devices.
