About Leonardo S

Hi there! I'm Leonardo, a security researcher with a passion for protecting user data. I'm a self-taught hacker who got my start in cybersecurity in 2020, when I was intrigued by a Twitter message proposing a Facebook bounty.I began my journey in network and web application hacking by completing hundreds of CTF tasks from Tryhackme and Hack The Box. I quickly improved my skills and rose to the top 1% of the Tryhackme platform.I'm now a bug bounty hunter, helping businesses to identify and fix security vulnerabilities before they can be exploited by malicious actors. I'm also a security researcher, working to develop new tools and techniques to help protect user data.I'm excited to continue my cybersecurity adventure and help to make the digital world a safer place for everyone.Here are some of the things that make me unique as a security researcher:I'm a self-taught hacker, which means I have a strong understanding of the fundamentals of cybersecurity.I'm a quick learner, which means I'm always up-to-date on the latest security threats.I'm passionate about protecting user data, which means I'm always looking for new ways to make the digital world a safer place.I'm looking for a company that shares my passion for cybersecurity and is committed to protecting user data. I'm confident that I can make a significant contribution to your team and help you to achieve your security goals.
