If, like me, you don&#x27;t know the term OSINT, it stands for &quot;open source intelligence.&quot;  What it means is publicly available information:  phone books, mailing lists, published documents and other things people can find just by snooping a little and not breaching a security system.  (Note:  According the Wikipedia, this is a US-centric view of the term and may be different where you live.)
