Also Known As:
- Commwarrior.A [F-Secure], SymbOS/Commwarrior.a [McAfee], SYMBOS_COMWAR.A [Trend Micro]
SymbOS.Commwarrior.A is a worm that replicates on Series 60 phones. It attempts to spread using Multimedia Messaging Service (MMS) and Bluetooth as a randomly named .sis file. If it is the first hour of the 14th of any month, the threat resets the device.
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.
Symantec offers a security solution for Symbian known as Symantec Client Security for Nokia Communicators. This product can be downloaded via the Nokia 9500/9300 web browser or from a PC. Symantec will never send unsolicited messages regarding one of our products. For additional information please see http://www.symantec.com/smallbiz/nok
