The World Economic Forum (WEF) highlighted growing concerns about cybersecurity in energy infrastructure following a major blackout across Spain and Portugal, which, despite no confirmed cyberattack, exposed vulnerabilities in national power grids. Experts stress the need for robust cybersecurity, especially as grids become more complex due to digitalization and renewable energy integration. Past incidents, such as Ukraine’s 2015 cyberattack and recent threats in the U.S., underscore the risk posed by increasingly sophisticated cyber actors. The EU and U.K. have responded with stronger regulations, but experts warn that resilience requires coordinated action across borders and industries. Practices like network monitoring, secure third-party management, and integrated threat detection are vital. The outage affected critical services including hospitals and transportation, and investigations continue. While cyberattack is not yet confirmed, security firms like Nozomi Networks observed suspicious activity during the event and emphasized the need for real-time visibility and preparedness in critical infrastructure.
