A forensics expert is performing file carving during an investigation. Which of the following tools could the forensics expert use?

In the context of digital forensics, file carving is a technique used to recover files from unallocated space or fragmented data on a storage device. The primary goal is to locate and reconstruct files without relying on the filesystem structure, making it essential for recovering data from deleted files or when the filesystem is corrupted.

Foremost is specifically designed for this purpose. It is an open-source tool that uses pattern matching to search for file headers, footers, and data streams in order to recover files, which makes it particularly effective in file carving scenarios. The utility is widely recognized in the forensic community for its efficiency and effectiveness in identifying and recovering a variety of file types based on their file signature patterns.

The other tools mentioned serve different functions in the realm of cybersecurity and digital forensics. Hexdump is used for displaying the raw hexadecimal content of files, which may assist in examining data, but it does not perform file carving. Ghidra is primarily a software reverse engineering tool developed by the NSA, and while it is powerful for analyzing binary executables, it is not intended for file recovery or carving. OllyDbg is a debugger primarily focused on analyzing and debugging Windows executables and does not have capabilities related to file recovery or carving.

Thus, Foremost
