  Recent high-profile cyberattacks on energy infrastructures, such as the
security breach of the Colonial Pipeline in 2021 and attacks that have
disrupted Ukraine's power grid from the mid-2010s till date, have pushed
cybersecurity as a top priority. As political tensions have escalated in Europe
this year, concerns about critical infrastructure security have increased.
Operators in the industrial sector face new cybersecurity threats that increase
the risk of disruptions in services, property damages, and environmental harm.
Amid rising geopolitical tensions, industrial companies, with their
network-connected systems, are now considered major targets for adversaries to
advance political, social, or military agendas. Moreover, the recent
Russian-Ukrainian conflict has set the alarm worldwide about the danger of
targeting energy grids via cyberattacks. Attack methodologies, techniques, and
procedures used successfully to hack energy grids in Ukraine can be used
elsewhere. This work aims to present a thorough analysis of the cybersecurity
of the energy infrastructure amid the increased rise of cyberwars. The article
navigates through the recent history of energy-related cyberattacks and their
reasoning, discusses the grid's vulnerability, and makes a precautionary
argument for securing the grids against them.
