What tool should you use when you need to analyze extracted metadata from files you collected when you were in the initial stage of penetration test (information gathering)?

Armitage is a graphical cyber attack management front-end for the Metasploit Framework, used for exploitation and post-exploitation, not metadata extraction.

Dmitry (DeepMagic Information Gathering Tool) is used for host-based OSINT such as WHOIS lookups and subdomain enumeration, not file metadata analysis.

Metagoofil searches for and downloads public documents (PDF, DOC, XLS, PPT, etc.) from a target domain and extracts embedded metadata such as usernames, software versions, email addresses, and server paths. This metadata is extremely valuable during the reconnaissance phase and can directly inform later attack stages.

cdpsnarf is a network packet sniffer that captures Cisco Discovery Protocol (CDP) frames to enumerate Cisco network devices and is unrelated to file metadata.
