✅ 📌 Introduction

API keys, access tokens, and secrets are the crown jewels of bug bounty hunting. When leaked, they can lead to unauthorized access, data breaches, and full system compromise. As a bug bounty hunter, discovering and exploiting these leaks can result in high-severity reports and significant bounties.

In this blog, I’ll cover 8 powerful tools used by professional bug bounty hunters to:

  • Detect, validate, and exploit leaked API keys and tokens
  • Automate key spraying against multiple services
  • Perform large-scale enumeration and verification

I’ll provide clear installation steps, usage examples, and pro tips to help you maximize your efficiency during bug bounties.
