Trojan:SymbOS/Romride.J affects devices running the Symbian S60 operating system. It is distributed in a malicious SIS file and when executed, installs components that cause the phone to 'crash', essentially becoming useless.
CAUTION! This method will remove all data on the device, including calendar and phone numbers:
Prevent future infections with F-Secure Mobile Security
On execution, Romride.J installs malfunctioning system component configurations. These components are designed to cause effects on the device, which may differ based on the version of ROM software installed. The message "Attack Successfully" is displayed, then the phone is immediately rebooted.
The effects produced by the system components are not seen, as Romride.J also installs a bootstrap component that reboots the phone every time it attempts to complete startup, leaving the phone in a continuous reboot loop.
