‍Analysis: Commercial Aviation Cybersecurity Threats in 2025‍

‍DALLAS — In 2025, the commercial aviation industry will face the highest number of Cybersecurity risks. Affected by the global reliance on technology and communication, cyberspace is vulnerable to cybercrime, IT outages, malware/ransomware attacks, data breaches, and associated fines and penalties. 

The aviation industry has seen a 24% increase in cyber attacks, with 52 reported in 2020, 48 in 2021, and 55 in 2022. Some attacks are military-related, while others involve passive methods like port scans, pings, and traffic monitoring. 

According to the TAC, 71% of attacks involve misappropriating login credentials and unauthorized IT infrastructure. Meanwhile, DDoS attacks targeting airlines and airports' online services represent 25% of cyber incidents. These incidents have increased due to various factors, including geopolitical tensions, increased digitalization, and expanding attack surfaces. 

Japan Airlines experienced a similar attack in December 2024, disrupting luggage services and delaying flights during the New Year holiday season.

Digital Transformation in Aviation

The satellite surveillance network enables easier tracking of aircraft worldwide. In addition to the pilot's utilization of advanced applications for flight planning and navigation in today's commercial flights, this digital infrastructure in aerospace enhances safety performance and intuitive handling of flight management.  

Networking software utilizes data analytics in planning and scheduling airlines and airports. Digitalizing aircraft enables manufacturers to collect real-time predictive and corrective maintenance data, promoting proactive maintenance and minimizing downtime. 

The aviation industry significantly expanded its investments in digital technologies for passenger handling, including self-service equipment, websites, mobile communications, and software packages. With the rapid spread of social networks and mobile apps, online fraud and unauthorised information dissemination have emerged. 

Networked applications also support passenger services like onboard bookings, in-flight entertainment, and Wi-Fi access. It became crucial not only for security screening and ground operations. Thanks to its cost efficiency and competition intensity, leading to improved customer experience and air transport. 

Digital transformation continues to grow with the rise of IoT, cloud computing, and AI-driven automation. Smart airports and real-time data exchange can enhance efficiency and introduce new cybersecurity vulnerabilities.

Negative impacts accompany these advancements from the opposite end of the runway. Unexpected System disruptions may result from data theft or breach, ransomware or malware attacks, or unauthorized access.

Major Cybersecurity Risks in Modern Aviation

Threats include malicious acts from hostile operators on ground or flight operations, such as GPS spoofing, which exploits weaknesses in an aircraft's navigation system. According to a Journal of Transportation Security study, around 65% of the attacks target airports and 35% hit airlines. 

1. Ransomware and Data Breaches: Ransomware, a type of malware, encrypts files on devices, preventing access to stored data. Access to airport security systems is being sold on the dark web. In global systems, breaches caused by hacking or information leakage increased from 4% in 2010 to 81% in 2024. In February 2025, the Arab Civil Aviation Organization (ACAO) was targeted by a cyberattack, resulting in the successful breach of its systems and the extraction of sensitive data. ‍
2. DDoS Attacks: Hackers target airports as critical infrastructure and state representatives, making them the focal point for cyberattacks aimed at weakening geopolitical positions and disrupting security measures. This is similar to the attacks targeting four key Taiwanese websites, including Taiwan Taoyuan International Airport. ‍
3. Communication Interference: The Aircraft Communications Addressing and Reporting System (ACARS) transmits short messages between aircraft and ground stations. This system can be exploited for data exchange. False information communication can pose a significant risk to the safety of aircraft, passengers, crew, ground personnel, and the general public at airports or civil aviation facilities.‍
4. Threats to Flight and Air Traffic: In 2024, the German air traffic control agency (DFS) experienced a cyber attack that disrupted its IT infrastructure. However, air traffic control operations and flights were not impacted. 
5. Airport Cyber Infrastructure: Violators interrupt the digital network through vulnerabilities to gain access to airport systems. They target various systems, including the Border Control database, the e-boarding Gate, the Departure Control of an airline, the Mobile App, the Airport Database, Self-service Kiosks, and Self-Bag Drop. 

All can raise significant concerns for the future; however, the ICAO strategy comprises international cooperation, governance, incident emergency management, and training. Investment in the global aviation cybersecurity market is expected to increase from US$4.6 billion in 2023 to US$8.42 billion by 2033.

Strategies Against Cyber Threats

The rapid evolution of AI and other advanced technologies is causing a rise in cyber threats, making them harder to detect and prevent. By 2025, these attacks are expected to become more sophisticated and frequent, posing a growing threat to critical infrastructure. At the same time, AI can be part of the solution for deterred systems.

Another bright side is that airports are trending toward modern frameworks, innovative delivery services, and strong governance methods for smooth, technology-enhanced operations. Aviation companies are deploying advanced cybersecurity frameworks, encryption protocols, and network segmentation to counter these risks.

Major companies like Raytheon, Thales, Honeywell, IBM, and Cisco lead the cybersecurity market for airlines, airports, and air traffic management systems. Emerging startups are leveraging AI, blockchain, and machine learning. Regulators, government, and strategic partners drive these dynamics. 

The International Civil Aviation Organization (ICAO) has been actively working on aviation cybersecurity since the 2000s. The organization is enhancing the international air law framework to combat cyberattacks on civil aviation and raising awareness about its importance. Many airlines are using real-time applications for flight optimization and security risk assessment.

Regulators are implementing advanced management systems to ensure safe cyberspace, with additional planning to do so by 2026. This trend is part of a broader trend towards sustainable operations, resulting in secure operations and cost savings. This rapid evolution is a significant step towards a more sustainable future.
