Bulk_extractor is the third and final tool that we'll cover in this chapter. Foremost and Scalpel, as we've seen so far, are quite impressive at file recovery and carving, but are limited to specific file types. For further extraction of data, we can use Bulk Extractor.

While Foremost and Scalpel can recover images, audio, video, and compressed files, Bulk Extractor extracts several additional types of information that can be very useful in investigations.

Although Bulk Extractor is quite capable of recovering and carving image, video, and document type files, other data that can be carved and extracted by Bulk Extractor includes:

• Credit card numbers
• Email addresses
• URLs
• Online searches
• Website information
• Social media profiles and information
