This paper describes research to identify and classify cyberattacks in the aviation industry in order to present the true reality of airports as a critical infrastructure and the threats that airport operators face. We conducted a critical review related to types of cyberattacks and supported by updated studies to analyse cyberattacks in the aviation industry from 2000 to 2023 due to the increase of attacks occurring in this period. Data was collected from verifiable sources such as the Center for Strategic and International Studies (CSIS), Federal Aviation Administration, EUROCONTROL, European Union Aviation Safety Agency (EASA), European Union Agency for Cybersecurity (ENISA) and KonBriefing. The findings of this study revealed that recent years have seen an increase in the number of distributed denial-of-service (DDoS) and ransomware cyberattacks at airports by foreign countries motivated by political and economic reasons, diplomatic espionage or even as part of a cyber war. This is particularly worrying, because the most influential international organisations and countries are recognising the existence of a cyber war in political, espionage, terrorism, safety, financial and commercial terms. The new contribution of this research lies in the fact that many uncertainties surround the cyberattacks that airport operators and commercial airlines face on a daily basis. Cyberattacks in the aviation industry are more common than most people realise, and the issue is that sometimes this information is silenced by governments, airport and airline operators to avoid unnecessary social alarm.
