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.
