Description
On June 18, 2022, employees at Elbląskie Przedsiębiorstwo Energetyki Cieplnej (EPEC) detected anomalies in the company's IT systems, leading to the identification of a malware infection. The IT department immediately initiated containment and recovery procedures, determining through testing conducted on June 18-19 that the ransomware attack had encrypted files within the network. While critical operational systems supporting the district heating infrastructure and emergency dispatch services remained fully functional, customer-facing platforms experienced disruptions. These disruptions prevented access to billing balance information, connection request status updates, and normal telephone communications through the main customer service line.

EPEC notified Poland's Internal Security Agency (ABW) about the incident and voluntarily escalated the matter to the Personal Data Protection Office (UODO), despite preliminary assessments suggesting no mandatory reporting obligation existed. The company prioritized transparency by announcing plans to mail formal notifications to customers about potential data exposure risks. A temporary customer service phone number (502 489 964) was activated while restoration work continued on the primary telephone system. EPEC confirmed all payment processing systems remained operational throughout the incident. Recovery efforts focused on fully restoring the compromised IT network, with ongoing analysis confirming ransomware as the attack vector. Customer communications included specific guidance on monitoring financial activity, recognizing phishing attempts, reporting identity theft concerns to law enforcement, and procedures for blocking identity documents through banking institutions. The company publicly apologized for service limitations while maintaining district heating operations without interruption.
