I’m George Vieru, a penetration tester with a strong focus on offensive security and hands-on experience across web application, infrastructure, and Active Directory environments. I’ve built and attacked vulnerable labs, completed a wide range of Hack The Box machines, and developed custom tools to automate tasks throughout the testing lifecycle.

My core strengths include web vulnerability exploitation (like SQLi, XSS, and command injection), AD attack techniques (such as Kerberoasting and lateral movement), and scripting with Python and Bash to streamline enumeration, exploitation, and post-exploitation workflows.

I’m especially interested in red teaming, malware development, and testing complex enterprise environments. My goal is to contribute to security teams by identifying and demonstrating real-world attack paths—so systems can be secured before they’re exploited.
