Internet security experts have spotted at least 36 more malicious programs targeting smartphone users this year including 'ikee', the first worm on Apple's iPhones. Chia Wing-fei, a security response manager at F-Secure, a Finnish firm that specialises in guarding against online threats, said they had detected 454 types of malware around the world targeting smartphones - 418 of them last year - some of them going after money. F-Secure said these types of malware would probably be found on currently worm-free mobile platforms, such as Android, next year. They are also expecting viruses targeting Microsoft's new operating system, Windows 7. Ikee was first found early last month. It replaces the wallpaper on an infected iPhone with a picture of British pop singer Rick Astley. Chia said a worm appeared a week later compromising bank transactions in the Netherlands. None of these iPhone infections have been reported in Hong Kong, but Chia said they could come at any time. 'It will be of no difficulty to hackers to change the codes and target bank transactions in Hong Kong,' he said.
