The Comisión Nacional de los Mercados y la Competencia (CNMC) in Spain has been the target of a massive cyberattack, resulting in the exfiltration of 2,000 million sensitive mobile phone records. The attack has prompted an investigation by the Audiencia Nacional, Spain's national high court, due to the scale of the data breach. The breach involved the theft of 240 GB of data related to mobile phone lines. The CNMC, responsible for overseeing competition and regulatory issues in various sectors, has not yet disclosed the full extent of the compromised information or the potential impact on its operations.
