The development of Information and Communication Technology (ICT) is converging with the aviation industry, evolving into various aviation services. The aviation industry now provides new forms of aviation services through the integration of advanced ICT technology. Consequently, it faces new cyber threats in the aviation sector, raising concerns about cybersecurity threats in the aviation industry. Typically, cyber threats have mainly targeted unauthorized access and administrator password theft for ground-based airline IT infrastructure and systems, malicious leaks, and theft of user information from airline users. Additionally, service denial attacks (DoS) that impair availability or disrupt system operations, and attacks that compromise the integrity of transmitted data, were common types of attacks. However, as in-flight network technology and services change, providing limited wireless network services, integrating and interconnecting in-flight systems based on TCP/IP, potential cybersecurity threats and vulnerabilities are exposed. In other words, as wireless network services are easily accessible within the aircraft, with passengers having easy access to the provided wireless networks, potential cyber threats to aircraft systems are increasing. This study is based on verified vulnerabilities observed in actual aircraft. It aims to analyze potential cyber threats that could occur in-flight, intentionally or unintentionally compromising the resilience of in-flight systems and causing service denial attacks.
