The coordinator of the National Cybersecurity Centre (CNCS), José Lino Alves dos Santos, stated that the entity never categorically ruled out a cyberattack regarding the April 28th blackout, but emphasized that there was no technical evidence to support such a claim. During a parliamentary hearing, he highlighted the challenges of managing misinformation during the crisis, noting that the priority was to verify information with operators and international partners. He also addressed the low rate of incident reporting by organizations and defended a selective communication strategy, prioritizing technical stakeholders over public alerts to avoid unnecessary alarm.
