Nos últimos meses, a Ucrânia vem sofrendo uma grande ofensiva de ataques cibernéticos às suas infraestruturas críticas. Assim, o objetivo deste trabalho é analisar quais ataques cibernéticos às infraestruturas críticas sofreu a Ucrânia dentro do recorte selecionado. Para isso, foi realizada uma pesquisa de método misto, que foi operacionalizada por meio de estatística descritiva, análise documental e revisão sistemática da literatura. Assim, a partir dos dados analisados do CyberPeace Institute, o setor mais atingido foi o de administração pública (66), enquanto a categoria de ataques mais utilizada foi de disrupção (139). Em seguida, avaliamos os tipos de ataques cibernéticos, sendo o mais utilizado o de tipo «DDoS» (135). Já na categoria de atores, a categoria «coletiva» (124), com destaque para o People&#8217;s CyberArmy (48), foi a de maior ocorrência. Em suma, concluímos que os ataques às infraestruturas críticas constituem uma questão de defesa nacional, sendo necessário revisar a legislação relacionada a esse tema e garantir que os órgãos responsáveis estejam preparados para enfrentar problemas futuros.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract What cyberattacks did Ukraine&#8217;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&#8217;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&#8217;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.]]></p></abstract>
