What formats of hash sets can be imported into FTK?

The correct answer is that all of the mentioned formats of hash sets can be imported into FTK.

FTK (Forensic Toolkit) supports various hash set formats to assist forensic investigators in identifying known files. The AccessData Hash Database (*.HDB) is specifically designed for use with FTK and contains MD5 and SHA-1 hash values for various files, allowing investigators to quickly find and handle files that match these known hashes.

The National Software Reference Library (NSRL) is another critical resource, providing a repository of known software, file profiles, and their associated hash values. This library enables forensic examiners to identify software and potentially malicious files during investigations.

KFF (known file filter) is a hash set created by AccessData, allowing users to define which files they want to categorize as known based on their hash values.

By being able to import all these formats, FTK provides extensive support for hash management, allowing for a comprehensive analysis of file systems by enabling the identification of known files, which can streamline investigations and enhance the efficiency of the digital forensic process. This capability is vital for forensic analysts in distinguishing between legitimate files and potentially harmful ones.
