A core dump is processed to locate and optionally alter sensitive information. A core dump copy is created from at least a portion of an original core dump. Also, at least one input parameter is provided that corresponds to select information to be identified in the core dump copy and address information associated with the core dump copy is defined that corresponds to at least one of addresses where the select information can be altered and addresses where the select information should not be altered. Each occurrence of the select information located within the core dump copy is identified and optionally replaced with predetermined replacement data if the occurrence of the select information is within the addresses where the select information can be altered.
