What is Intruder?

Intruder, a core component of Burp Suite Professional, is a powerful and highly customizable tool for automating customized attacks against web applications. It's primarily used for tasks like identifying and exploiting web application vulnerabilities through techniques like fuzzing, brute-force attacks, and testing for injection flaws. Security professionals use Intruder to simulate real-world attacks, assess the security posture of web applications, and pinpoint weaknesses before malicious actors can exploit them. It allows for sending sequences of HTTP requests with defined payloads and analyzing the responses to identify vulnerabilities or weaknesses.
