Additional Details
KBlock is a trojan for Series 60 1st and 2nd Edition phones.
Once KBlock is installed, it prevents normal usage of the phone by automatically locking the keypad and keeping it locked. The user is still able to answer incoming calls, but access to any other phone functions is prevented as the trojan blocks usage of the keypad.
The trojan uses parts of commercial software to gain its functionality through a front end processing component (fep).
