This book is a systematic and practical introductory guide to bug hunting, designed for those who have finished learning the basics of web security and are ready to achieve the real-world milestone of obtaining their first CVE ID.

While there are many learning resources and practice environments available, mastering them is often not enough to break through the barrier of finding vulnerabilities in real products and successfully securing a recognized CVE.

Focusing on open-source software (OSS) on GitHub, this book condenses the author's personal expertise into a 30-day roadmap. It covers everything from selecting target OSS and \"search techniques\" for finding vulnerabilities within vast amounts of source code, to \"code review\" for understanding implementations and the \"reporting skills\" required to have a vulnerability officially recognized.

Through this book, let's take your first step from being a mere \"learner\" to becoming a \"bug hunter.\" I hope that in 30 days, your first CVE ID—with your name etched into history—will be issued.

Recommended People

Those who want to try obtaining a CVE ID
Those who are motivated and enthusiastic
