Fundamentals Recon is 80% of offensive security. The researchers who earn six figures aren’t running more tools than everyone else — they’re running them in smarter pipelines, feeding the output of one into the next, and manually reviewing the long tail that automation misses. Every hour spent deepening the asset inventory pays off when hunting begins: more subdomains means more parameters, more endpoints, more code paths, more chances for a bug nobody else has seen. ...
