What is tetheros?

Tether OS is a bootable Linux distribution built for anonymous penetration testing, meaning security professionals testing systems with permission. It routes all network traffic through the Tor anonymity network and automatically rotates its exit node every 60 seconds, so the visible IP address keeps changing. The whole system fits inside a 27 megabyte ISO file and runs entirely from RAM rather than needing to install anything to disk. It can also be installed as a regular desktop application on Windows, Linux, and macOS instead of booting it directly. Once running, users get a custom terminal shell styled after coding assistant interfaces, complete with a dark theme, animated startup screen, and a matrix style rain effect. The shell includes more than 90 built-in commands covering reconnaissance, exploitation, digital forensics, web scanning, wireless testing, and scheduled tasks, plus command piping and output redirection similar to a normal Linux terminal. It also has its own small virtual filesystem with familiar commands like cd, ls, cat, and mkdir, a scripting format for running saved command sequences, four color theme presets, and automatic session logging so past commands can be reviewed or a session state restored later. Underneath the shell sits a custom Linux kernel with a firewall rule that blocks any traffic that is not going through Tor, acting as a kill switch if the anonymity connection drops. Tor itself starts automatically at boot with its proxy service and control port active. The project can be run quickly inside the QEMU emulator for testing, written to a USB drive to boot on real hardware, or installed as a Python package for the desktop app version. The codebase is organized into a shell interface layer, a set of command modules grouped by purpose, and a lower kernel layer handling Tor control and IP rotation. It is released under the MIT license.</content>
