Analysis of the new virus mentioned in the previous posting showed that it’s a SymbianOS worm, based on Cabir source code, that spreads itself via BlueTooth. It also has a file infection functionality.
Upon execution, the virus searches for nearby BlueTooth devices (those which are in discoverable mode) and tries to transmit itself to any accessible ones. It also initiates a drive-wide scan for SIS-files and tries to infect them by inserting virus code directly into an SIS archive.
We’ve called this virus Worm.SymbOS.Lasco.a. An antivirus database update is already available.
A detailed description of the virus will be available in the Virus Encyclopedia in the near future.
UPDATE: the description of Lasco.a is now online.
