Raonsecure's white hat hackers have once again proven their world-class cybersecurity capabilities by advancing to the finals of "DEF CON CTF," one of the most prestigious global hacking competitions. The company plans to further strengthen its premium security services by combining practical security competitiveness with artificial intelligence (AI) utilization skills and specialized expertise.

Raonsecure, an AI security and authentication platform provider, announced on the 28th that all 23 of its white hat hackers secured spots in the finals during the recent "DEF CON CTF 2026" qualifiers.

DEF CON CTF is an international hacking competition, often called the "Hacking Olympics," where the world’s top white hat hackers compete in vulnerability analysis, attack and defense skills, and problem-solving abilities. This year’s qualifying round saw participation from 686 teams worldwide, of which only 12 teams advanced to the finals, which will take place in Las Vegas, USA, this August.

In the competition, Raonsecure divided its 23 white hat hackers into three teams, and every team they participated in successfully reached the finals. The company explained that achieving results across multiple teams simultaneously demonstrates its talent pool of world-class white hat hackers.

AI-powered analytical capabilities also played a major role in this accomplishment. Given the competition’s structure, which requires solving advanced tasks such as vulnerability analysis, cryptography, and web hacking within tight deadlines, leveraging AI to quickly understand the problem structure and identify solutions contributed directly to this competitive advantage.

Raonsecure’s white hat hackers consistently participate in domestic and international cyber defense competitions, accumulating expertise in both the latest attack methods and defense strategies. The company has also built collaborative systems with experts specializing in web security, reverse engineering, Internet of Things (IoT), mobile, and pwnable (system vulnerability exploitation), further strengthening team play for tackling complex problems.

Such achievements stem from the technical capabilities built up over years by the Raonsecure White Hat Center. The center is recognized as one of the leading white hat hacker organizations in Korea and has consistently posted strong results in major global hacking competitions.

For example, team leaders Kim Dongmin and Choi Yongseon together won the SECCON CTF in Japan, the National Intelligence Service’s Cyber Attack and Defense Competition (CCE) in the public sector, and placed fourth in the DEF CON CTF finals, among other notable performances in both international and domestic events.

As a national-designated information security service provider, Raonsecure is expanding its portfolio of practical security services such as premium penetration testing, leveraging its white hat hacker teams. By assessing the vulnerabilities of client systems, as real attackers would, and verifying the possibilities of intrusion, lateral movement, and information leakage, Raonsecure is enhancing its clients’ security response capabilities.

The company plans to continue evolving its next-generation security validation systems by combining the practical experience of white hat hackers with AI technologies, given the rapid changes AI brings to the cyber offense and defense landscape.

Yoon Wonseok, Head of Raonsecure’s White Hat Business Division, stated, “Advancing to the DEF CON CTF finals is concrete proof of Raonsecure white hat hackers’ elite operational security capabilities. As AI shifts the paradigms of attack and defense, we will continue to strengthen security validation systems that integrate the expertise of white hat hackers with advanced AI utilization, helping businesses defend against real-world cyberattacks.”

This achievement is significant in that it demonstrates Raonsecure’s globally competitive edge based on top-tier white hat hacker capabilities and AI-driven security technologies, solidifying the foundation for the expansion of next-generation security services.
