is it possible to extract a pattern from a router firmware file ? as you can see the default ssid which is ISP-(some 4 random characters) mostly contains characters that are in the password. another collected ex. ssid:ISP-bHzX pass:3Xg6HuJL ssid:ISP-vVJC pass:Uvq3RZuz ssid :isp-SvfP pass:s4VT2RTt the firmware grabbed using FTP as i couldn't find it anywhere https://ufile.io/gfyh6242 i am not sure that there is even a pattern but i just think that.
