recon me is an OSINT tool developed by mgm Security Partners and used as part of the company's OSINT analysis service. The tool collects and correlates publicly available information about an organization's external attack surface, including domains, subdomains, servers, technologies used, metadata, and publicly accessible files. It supports two scan modes: - Passive scan: queries public directory services such as Whois, DNS, and MX records to identify servers, subdomains, email addresses, technologies, and operators (e.g. Amazon, Akamai) without any interaction with target systems. - Active scan: directly examines the target domain without performing attacks, to identify additional services, technologies, or unintentionally exposed files. Results from recon me are combined with manual expert analysis and used to produce a report detailing identified assets, potential vulnerabilities, misconfigurations, and prioritized recommendations. The output is intended to give organizations a view of their public attack surface from an attacker's perspective and can serve as a basis for further security testing such as penetration tests.</description> <parameter name="summary">Proprietary OSINT tool for mapping an organization's public attack surface
