Significant events to be reported: Cyber Attack in Progress

Electrica Group is under a cyber attack. The teams of specialists are working closely with the national cybersecurity authorities to manage and resolve the incident, aiming to address the situation as quickly as possible, identify the source of the attack, and limit its impact.

We want to emphasize that the Group's critical systems have not been affected, and any disruptions in interaction with our consumers are the result of protective measures for internal infrastructure. These measures are temporary and are designed to ensure the security of the entire system.

At this time, all specific response protocols have already been activated in accordance with internal procedures and current regulations. Our primary priority remains maintaining continuity in the distribution and supply of electricity, as well as protecting the managed personal data and the operational data of all entities within Electrica Group.

We will continue to keep the public informed about the situation's developments and the measures being taken to resolve it. In this context, we recommend that our consumers remain vigilant about any suspicious messages received in the company's name and avoid providing personal data through unsecured channels.
