Also Known As:
Pbstealer.A [F-Secure]
Type:

Systems Affected:
EPOC


SymbOS.Pbstealer.A is a Trojan horse that runs on the Symbian OS, which is used as the operating system for Nokia Series 60 cellular telephones. The Trojan sends the user's contact information database to other Bluetooth-enabled devices.

SymbOS.Pbstealer.A reportedly arrives as PBEXPLORER.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.
