Introduction️ Various devices marketed in the market both for acquisition by consumers and for rental by Internet service providers’ clients allow their administration through a web portal. This portal may be limited in features and if more advanced configurations are needed, such as configuring the firewall, with the iptables tool, access via console is necessary. The operating system of routers usually is GNU/Linux.️ The console access is usually blocked to prevent problems with incorrect configurations made by inexperienced users, which makes it necessary, for example, to access the serial port by removing the device casing. In other cases, access to the console is allowed through the SSH (Secure Shell) protocol, but access is limited to a restricted console, with pre-defined commands from the manufacturer. These devices usually have a backdoor that allows deploying a command terminal sh or bash with the introduction of specific commands.️ ...

Introduction️ There are additional protections related to the requirement for a specific TLS certificate (pinning). There is also the possibility of encrypting network communications over the HTTP protocol. In the case of symmetric encryption, the application will obtain the key from the server or obtain it from the application’s own source code, statically (stored in a variable), or dynamically, where several obfuscated methods will be executed to create the key to use. ...
