Although concerns regarding handheld data security still trump fears of mobile viruses, security software vendors and researchers contend that greater numbers of attacks are on the horizon.
Thus far, most malware programs targeting wireless devices have been proof-of-concept threats or have required large amounts of end-user interaction to deliver their payloads, but experts contend that malware writers are unquestionably ramping up their efforts in the space.
According to anti-virus applications maker F-Secure, there are already more than 370 different wireless threats in the air, including attacks that attempt to delete data stored on handhelds and even record end-users’ phone calls.
Over the next year, security vendors expect to see new threats aimed at wireless transactional systems and users of less sophisticated handheld hardware.
“As the addressable market for smartphones expands, there will be more attacks,” says Jan Volzke, head of marketing for mobile security at McAfee.
