When it comes to the most notorious ethical hackers in the world, a few names come to mind. These individuals have made significant strides in the field of cybersecurity, uncovering vulnerabilities in some of the world's most prominent organizations and systems.

One of the most well-known ethical hackers is Kevin Mitnick. Mitnick is a former hacker who once served five years in prison after being caught breaking into computer systems. After serving his time, he turned his skills towards ethical hacking, and he's now known as a respected security consultant. Mitnick is famous for a series of high-profile hacks in the 90s, including breaking into the computer systems of Motorola, Sun Microsystems, and Tsutomu Shimomura, who was a well-known cybersecurity expert.

Another individual worth mentioning is Samy Kamkar. Kamkar is best known for creating the first self-propagating virus on Myspace in 2005. After being caught by the FBI, Kamkar was banned from using computers for three years. However, he eventually turned his focus towards ethical hacking, and he's now a respected security researcher. Kamkar has uncovered vulnerabilities in a number of high-profile systems, including Google's Android platform and Microsoft's Internet Explorer.

A third ethical hacker worth mentioning is Dan Kaminsky. Kaminsky is a renowned security researcher who's responsible for discovering a critical flaw in the Domain Name System (DNS) in 2008. Kaminsky's discovery led to a massive coordinated effort to fix the vulnerability before it could be exploited by attackers. Kaminsky is also known for identifying vulnerabilities in a number of popular software programs, including the popular open-source encryption software called OpenSSL.

Finally, we have Joanna Rutkowska, a Polish security researcher who's known for her work on rootkits and virtualization technology. Rutkowska has discovered a number of vulnerabilities in popular virtualization systems, including VMware, and she's also developed a number of 'stealthy' malware programs that can evade detection by traditional security software. Rutkowska is also the founder of the Invisible Things Lab, which is dedicated to conducting research on advanced hacking techniques.

In conclusion, these four individuals represent some of the most notorious ethical hackers in the world. They've made tremendous contributions to the field of cybersecurity, uncovering vulnerabilities that could have been exploited by attackers to wreak havoc in both the public and private sectors. Through their work, they're helping to make the internet a safer place for everyone, and they serve as an inspiration to the next generation of ethical hackers.
