SymbOS.Cabir.W is minor variant of SymbOS.Cabir
. This worm also spreads through Bluetooth-enabled devices running the Symbian OS, which is used as the operating system for Nokia Series 60 cellular telephones.
The worm arrives on a Bluetooth-enabled device as the file inbox.sis.
It may also be dropped by SymbOS.Cardtrp.M
as the file Norton Antivirus symbian V1.0.SIS.
Symantec recommends the following to protect against this threat:
- If Bluetooth is not required, it should be turned off.
- If you require the use of Bluetooth, ensure that the device's visibility setting is set to "Hidden" so that it can not be scanned by other Bluetooth devices.
- Avoid use of device pairing. If it must be used, ensure that all paired devices are set to "Unauthorized". This requires each connection request to be authorized by the user.
- Do not accept unsigned applications (no digital signature) or applications sent from unknown sources. Be absolutely sure of the origin of the application before accepting it.
