In some setups, the 'Guest' Wi-Fi network can even show you a page with the password to the second 'Secure' Wi-Fi network in plain text, just by navigating to the router's IP address. Scanning a network with Fing can lead to many exciting discoveries because often the people who set up the network do so in ways that don't make any sense. In an advanced attack, Fing can be used to rapidly obtain targeting information to guide powerful, Hydra password cracking attempts. While primarily an information gathering tool, the Fing network scanner actually allows us to connect directly to a wide range of devices by guessing the password. Networks scanners are recon tools for finding vulnerabilities and are often seen as the first stage in an attack. And if you haven't changed the default password on these devices, an attacker can simply try plugging them in.
Most networks allow users to scan and attempt to log in to these connected devices. Sharing your Wi-Fi password is like giving an unlimited pass to snoop around your network, allowing direct access even to LAN-connected devices like printers, routers, and security cameras.
