Spain Investigates Cyberattack Claims After Widespread Power Outage

A massive power outage on April 28 left millions in Spain, Portugal, and neighboring regions without electricity, severely affecting transport, banking, and communications. The Spanish government and judiciary have launched parallel investigations to determine the cause of the blackout, including the possibility of a cyberattack, though the national electricity operator has so far dismissed this theory. Prime Minister Pedro Sánchez has called for urgent cooperation with private energy firms, emphasizing that all hypotheses remain on the table and promising reforms to safeguard the country’s electric grid. Portugal has requested an independent EU audit to further examine the event. The classified nature of the Spanish judicial probe aims to protect the integrity of the investigation, while official commissions and technical teams are expected to provide initial findings soon.
