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

We carry out lots of attack surface assessments, parts of which involve investigating information that has been unintentionally disclosed. To help OPSEC people I thought it might be useful to go over some of the key things that can be found using domain and company names. Domain name So let’s div...
