Information:
SymbOS.Cabir.C is a proof-of-concept worm that replicates on Series 60 phones. The worm is a minor variant of SymbOS.Cabir.
The only differences are:
The worm spreads as ni&ai-.SIS.
The worm displays the following message after infection:
ni&ai-
The worm repeatedly sends itself to the first Bluetooth-enabled device that it can find, regardless of the type of device. For example, even a Bluetooth-enabled printer will be attacked if it is within range.
The worm spreads as a .SIS file, which is installed into the APPS directory. There is no payload, apart from the vastly shortened battery life caused by the constant scanning for Bluetooth-enabled devices.
technische Details:
SymbOS.Cabir.C is transmitted through Bluetooth as a .SIS file.
When the worm arrives at a target device the following may happen:
The device displays a message similar to the following, asking the user to accept a message from a particular device:
Receive message via Bluetooth from [device name]?
The user will be notified that they have received a new message.
The user will be prompted with a message similar to the following:
Application is untrusted and may have problems. Install only if you trust provider.
If the user chooses Yes, the user will be prompted to install the worm.
Install ni&ai-?
If the user chooses Install, the worm is installed, executed, and then displays the following message:
ni&ai-
The worm creates the following files on the phone:
\SYSTEM\APPS\ni&ai-\ni&ai-.APP
\SYSTEM\APPS\ni&ai-\ni&ai-.RSC
\SYSTEM\APPS\ni&ai-\FLO.MDL
C:\SYSTEM\SYMBIANSECUREDATA\ni&ai-SECURITYMANAGER\ni&ai-.APP
C:\SYSTEM\SYMBIANSECUREDATA\ni&ai-SECURITYMANAGER\ni&ai-.RSC
C:\SYSTEM\SYMBIANSECUREDATA\ni&ai-SECURITYMANAGER\ni&ai-.SIS
C:\SYSTEM\RECOGS\FLO.MDL
C:\SYSTEM\INSTALLS\ni&ai-.SIS
The worm attempts to send itself to other Bluetooth-enabled device that it finds, regardless of the type of device.
The worm executes every time the device is turned on.
