Create own Hacking SERVER Instead of Portswigger exploit server

Summary
The article discusses creating a server to exploit Cross-Origin Resource Sharing (CORS) vulnerabilities, a common security issue.
The server is built using Express.js or Flask in Python, two lightweight and popular web development frameworks.
The server is configured to listen on a specific port, and it has a single endpoint defined for logging data.
When a client accesses this endpoint (with a key parameter), the server logs the exfiltrated data (or key) and responds with a success message.
To access the server locally, npm start is used for Express.js and python app.run() for Flask.
Using Ngrok, port-forwarding allows the server to be accessed remotely, useful for vulnerabilities that require an attacker to attract a target to a malicious server.
