DEFCON is considered as the first hackers conference.

Explanation:
DEFCON, short for "Defense Readiness Condition," is a well-known annual hacker convention that takes place in Las Vegas, Nevada. It is considered the first hackers conference and has been held since 1993. DEFCON brings together hackers, cybersecurity professionals, government agencies, and enthusiasts from around the world to discuss and showcase the latest advancements and vulnerabilities in the field of cybersecurity.

Below are the reasons why DEFCON is considered as the first hackers conference:

1. Foundation: DEFCON was founded by Jeff Moss, also known as "Dark Tangent," who is a prominent figure in the cybersecurity community. He established DEFCON as a gathering for hackers to share knowledge, exchange ideas, and demonstrate their skills.

2. Focus on Hacking: DEFCON primarily focuses on hacking techniques, vulnerabilities, and cybersecurity challenges. It covers a wide range of topics including network security, cryptography, social engineering, hardware hacking, software vulnerabilities, and more.

3. Hacker Community: DEFCON has become a hub for the hacker community, attracting individuals with a keen interest in cybersecurity, hacking, and technology. It provides a platform for hackers to network, collaborate, and learn from each other.

4. Capture the Flag (CTF) Competitions: DEFCON hosts various Capture the Flag competitions, where participants solve cybersecurity challenges and exploit vulnerabilities to gain points. These competitions showcase the skills and creativity of hackers in a controlled environment.

5. Presentations and Workshops: DEFCON features numerous presentations and workshops by experts in the field of cybersecurity. Attendees can learn about the latest hacking techniques, research findings, and defense strategies through these talks and workshops.

6. Ethical Hacking and Responsible Disclosure: DEFCON promotes ethical hacking and responsible disclosure practices. It encourages hackers to identify vulnerabilities in systems and report them to the appropriate authorities instead of exploiting them maliciously.

In conclusion, DEFCON is considered the first hackers conference due to its focus on hacking, the foundation laid by its founder, its role in fostering the hacker community, and its contributions to cybersecurity knowledge and awareness.
