: It complements "Google Dorking" by scanning the actual IP space rather than just relying on what search engines have indexed. Installation and Requirements
: Finding open webcams or administrative interfaces that lack proper password protection.
As an open-source project, NESCA is typically hosted on platforms like GitHub .
