OSINT. What can you find from a domain or company name

This guidance outlines common reconnaissance techniques leveraging a target's domain and company names to uncover subdomains, IPs, TLS certificates, email configurations, staff/contact data, code repositories, and breached credentials, explaining how these exposures can be combined to enable phishing, spoofing, supply-chain, and physical attacks; it concludes with practical recommendations (e.g., Google dorks, DNS/TLS/IP asset discovery, supplier monitoring, and social media hygiene) and encourages emulating MITRE ATT&CK reconnaissance to understand and reduce the attack surface.
