AMSTERDAM (June 16) - A group of underground virus writers has showed off what is believed to be the world's first worm that can spread on advanced mobile phones, but security software companies say the virus had no malicious code attached.
The worm, named Cabir, was sent to security software firms Kapersky Lab of Russia and U.S.-based Symantec by a member of 29a, a group of virus writers from the Czech Republic and Slovakia who pride themselves in creating ''proof of concept malicious viruses,'' Kapersky Labs spokesman Denis Zenkin said.
''This is the very first version of a network worm which propagates via mobile phones,'' he said on Wednesday.The worm is designed to work in smartphones running on Symbian and Series 60 software, Symantec said on its Web site.This software is used to power millions of Nokia phones, such as the popular 6600 model.
