GRBG (Garbage)

GRBG is a Go-based fuzzer designed for CTFs (Capture The Flag competitions). It is a lightweight tool with no external dependencies, making it easy to use and deploy.

Active Development

Currently, GRBG has one exploiter implemented, which is the format string exploiter. This exploiter allows you to perform format string attacks during CTFs. We are actively working on adding more exploiters to enhance the capabilities of GRBG.

Features

• No Dependencies: GRBG does not rely on any external libraries or packages, ensuring a seamless setup process.
• Exploiter Interface: The fuzzer can be easily expanded and customized using the exploiter interface, allowing you to tailor it to your specific needs.
