Provided are an apparatus and method for searching for digital forensic data. In particular, provided are an apparatus and method for searching for digital forensic data capable of automatically determining a character encoding type that is used in searching for data. The apparatus for searching for digital forensic data includes: an imaging module for generating an image file from a data source; a file system analysis module for analyzing a file system of the image file to generate file system analysis information; a search module for determining a search character encoding type based on the file system analysis information and searching for the data using the search character encoding type; and a user interface for receiving a command related to a search from a user, transmitting the received command to the file system analysis module and the search module, and outputting the search results to the user. In searching for digital forensic data, information on an operating system, a processor and an active character encoding type, which are actually used by a suspect, is extracted to determine a search character encoding type, so that accuracy and efficiency of searching for data are increased, and time, effort and money spent in determining a character encoding type are reduced.
