The source code used to create the original Cabir worm has been posted on the Internet by a member of an international virus-writing group, leading to fears that the code will be used to create an inundation of new and potentially dangerous mutations of the worm on smart phones running the Symbian Series 60 software. Prior to this, the Cabir source code was previously accessible only to a limited number of people, including members of 29A, an international virus-writing group.
"It was a 29A member who wrote the original version of Cabir. We think it was planned to publish the source code in the next edition of the group's electronic journal. However, it looks that someone has already got access to the code, and now it's public. This will lead to a lot of new versions of Cabir, which has already been detected in the wild in 7 countries." - Kaspersky Lab senior virus analyst Aleks Gostev.
Although the worm has not been directly vicious or malevolent, it is capable of blocking normal Bluetooth connectivity, and is also capable of completely draining the battery power from an infected phone.
