Third-generation (3G) cell phones are more exposed to viruses than their less technologically advanced predecessors, as users are subject to a higher risk of having their personal data stolen, an expert said yesterday. «The new generation of phones involves new dangers and less protection,» said Giorgos Pangalos, a professor at Aristotle University of Thessaloniki. «Mobile phones using the latest technology are small electronic computers. Because they have a limited volume, weight and price, they cannot have safety mechanisms (firewalls) included,» he added. According to a recent survey, about 13 percent of mobile phone users in Greece have a 3G appliance. «New mobile phones can be subject to attacks from viruses… with attackers being able to take information from users on banking transactions,» said Pangalos.
