Using Python to Spy on Your Friends: Recon-ng and Open Source Intelligence
summary
Automates verifying and expanding a single email into a mapped online identity using Python tools: posts to a public validator (mailtester) then parses its HTML with lxml and an XPath expression to conclude validity, runs FullContact to enumerate profiles (87% confidence reported), and uses recon-ng as a local database and module glue to chain lookups; the mail-checker module is 35 lines of Python, works reliably, and is easy to inspect or reimplement.
