HULK is a Go-based DoS tool designed for efficient stress testing of web servers using lightweight goroutines for high concurrency.
HULK DoS tool ported to Go with some additional features.
This tool is primarily used for stress testing web servers to identify vulnerabilities related to denial-of-service attacks, making it valuable for penetration testers and red teamers. It helps security professionals evaluate the resilience of web applications and infrastructure under heavy load conditions.
Use this tool responsibly as it can severely impact poorly configured servers or applications. Ensure you have proper authorization before conducting stress tests. Adjust environment variables like GOMAXPROCS and HULKMAXPROCS to optimize performance based on your hardware capabilities.
