Back Orifice Detection Preprocessor

The Back Orifice preprocessor analyzes UDP traffic for the Back Orifice magic cookie, "*!*QWTY?", which is located in the first eight bytes of the packet and is XOR-encrypted.

The Back Orifice preprocessor has a configuration page, but no configuration options. When it is enabled, you must also enable preprocessor rules for the preprocessor to generate events and, in an inline deployment, drop offending packets.
