Also Known As:
Trojan Horse
Systems Affected:

SymbOS.Fontal.C is a Trojan horse that affects Symbian series 60 phones and causes the compromised device to continuously restart.

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.
