What cyberattacks did Ukraine’s critical infrastructure experience between February 2022 and February 2023 during the Russo-Ukrainian war? In recent months, Ukraine has experienced a significant increase in cyberattacks on its critical infrastructure. Therefore, the purpose of this study is to analyze the cyberattacks suffered by Ukraine’s critical infrastructure within the selected cutout. A mixed method research approach was used, operationalized through descriptive statistics, documentary analysis, and a systematic literature review. Based on the analyzed data from the CyberPeace Institute, the sector most affected was public administration (66), with the Disruption attack category being the most utilized (139). The types of cyberattacks were also evaluated, with the DDoS type being the most common (135). The collective (124), especially the People’s CyberArmy (48), was the most common in the actor category. In conclusion, we can say that attacks on critical infrastructure are a matter of national defense, which requires a revision of legislation on this issue and ensuring that the responsible bodies are prepared for future challenges.
