    BigBountyRecon

    Automates reconnaissance for bug bounty and penetration testing target

    BigBountyRecon is an open source reconnaissance tool designed to assist security researchers, penetration testers, and bug bounty hunters during the early stages of security assessments. It automates the collection of publicly accessible information about a target organization by combining numerous reconnaissance techniques with widely used Google dorks and other open source resources. Its main goal is to accelerate the information-gathering phase, which is often considered one of the most important steps in penetration testing and bug hunting. By quickly identifying potential information leaks and publicly exposed resources, the tool helps users gain an initial understanding of the target’s security posture. BigBountyRecon allows researchers to perform multiple reconnaissance checks without having to manually remember or craft complex search queries. It aggregates results from dozens of discovery techniques so analysts can identify possible entry points and weak configurations.
