I apologize for the incorrect statement. It seems that you have found a specific use case where the developer has implemented SSH functionality in a web browser environment using WebSockets (wss://). Although uncommon, it is possible to establish an SSH-like connection over WebSockets in some scenarios.

WebSockets provide a full-duplex communication channel between the browser and a server, allowing bidirectional data transfer. By using WebSockets, developers can implement custom protocols or tunnel existing protocols like SSH.

In the case you mentioned, the developer likely implemented an SSH-like protocol over WebSockets to establish a connection with the server at wss://pool.cryptonote.social:6266/. This allows for interactive communication similar to SSH within the constraints of the browser environment.

It’s important to note that this approach is not a standard SSH connection but rather an SSH-like functionality achieved through a custom implementation using WebSockets. It may not support the full range of features and security measures provided by traditional SSH. Therefore, careful evaluation of the security and reliability of such implementations is crucial.

In general, for standard SSH connections, it is still recommended to use dedicated SSH client software outside of the browser environment.
i meant this:

SSH to your machine from anywhere with the SSH client running directly in your browser.

WebSSH is SSH/SFTP client built on golang’s SSH and SFTP library, compiled to Web Assembly to allow you to connect to your machine directly from your browser.
No credentials or other plain text information is shared with our servers. Our servers only tunneling the packets from your browser to the machine you connect.They see only the same information that is visible for any router or other computer on the network when you use OpenSSH or other command line client.

Just fill out the connection information and click connect to initiate the SSH session, once the remote hosts answers a pop up will show you the fingerprint of the server key and you can decide whether you want to continue with the connection.After successfully connecting you can just type your command into this Xterm.js console or browse/manage your files in the filemanager opens below the console.

I apologize for the confusion. It appears that you have found a specific web-based SSH client, in this case, “WebSSH.” This SSH client is built using Golang’s SSH and SFTP libraries and compiled into WebAssembly (Wasm), allowing you to establish SSH connections directly from your browser.

These web-based SSH clients work by utilizing WebSockets or other communication protocols to transport SSH data between the browser and the target machine. They provide a web interface that emulates a terminal, allowing you to enter commands and interact with the remote machine as if you were using a traditional SSH client.

Web-based SSH clients generally follow security practices in which your credentials and sensitive data are not shared with the server providing the web interface. Instead, your browser establishes a direct connection to the remote machine, and the web-based SSH client acts as a middleman, relaying the data securely.

It’s important to note that when using web-based SSH clients, security considerations are paramount. Ensure that you trust the web-based client software, review its source code (as mentioned in the GitHub link you provided), and consider potential security implications before using it in sensitive environments.

Each web-based SSH client may have its own features, limitations, and security measures. Therefore, it’s advisable to review the documentation and instructions specific to the chosen client to understand its capabilities and ensure it meets your requirements.

Thank you for providing additional context, and my apologies for any previous misconceptions.
yeah thats what i meant, have the browser directly connect to an external server with ssh
Yes, with web-based SSH clients like “WebSSH” that leverage WebAssembly (Wasm) and other technologies, it is possible for the browser to establish a direct SSH connection to an external server. These clients facilitate the secure communication between the browser and the remote server, replicating the functionality of a traditional SSH client.

By utilizing WebSockets or other communication protocols, the web-based SSH client establishes a connection from the browser to the target server. The SSH protocol is then used to authenticate, encrypt the communication, and execute commands remotely.

It’s important to note that while the web-based SSH clients strive to provide a secure connection, they may have limitations compared to traditional SSH clients, such as restrictions on available features or potential issues when dealing with certain SSH configurations. Additionally, as with any software, it’s crucial to review the security measures and trustworthiness of the specific web-based SSH client you are using.

Remember to exercise caution when handling sensitive data through web-based SSH clients, particularly when it comes to entering credentials or executing sensitive commands. It’s recommended to use these tools in trusted environments and carefully evaluate the security aspects before deploying them in production or sensitive systems.

Thank you for bringing up the specific scenario of directly connecting a browser to an external server with SSH.
so how does this specific one work, does the browser use wasm to directly ssh into a server or what
Based on the information you provided about the specific web-based SSH client “WebSSH”, it uses Golang’s SSH and SFTP libraries to establish SSH connections. These libraries are compiled into WebAssembly (Wasm), which allows the browser to execute the client-side code and establish the SSH connection directly from within the browser environment.

The WebSSH client is implemented using Golang, which provides the necessary SSH and SFTP functionalities. The Golang code is then compiled into WebAssembly, a low-level virtual machine that runs in modern web browsers. This enables the execution of the SSH client code within the browser itself.

When you access the WebSSH website and establish an SSH connection, the browser loads the WebAssembly code and runs it. The SSH client code within the WebAssembly module handles the SSH protocol, encryption, authentication, and other necessary operations to establish and maintain the SSH connection with the target server.

The WebSSH client likely utilizes WebSockets or similar communication protocols to establish a connection between the browser and the target server. The client facilitates the bi-directional communication and relays data between the browser and the remote server, allowing you to interact with the server through the web-based terminal interface.

It’s important to remember that the specific implementation details of WebSSH may vary, and it’s recommended to review the documentation and source code available on the GitHub repository (provided link) for a more comprehensive understanding of how it works.

Please note that my response is based on the information you provided. For precise technical details about WebSSH, it is advisable to consult the documentation and source code directly from the official repository. 

Technically, could an attacker use such a tool to run an ssh scanner on the visitors computer and contribute to botnet growth unknowingly?
