SymbOS.Commwarrior.C is a worm that replicates on Series 60 phones. It attempts to spread using Bluetooth, Multimedia Messaging Service (MMS), and Multmedia Cards (MMC) as a randomly named .sis file. It has been reported that one of the possible file names is SymCommander_1_06.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.
