The incident follows a series of digital attacks on Polish public institutions Polish authorities say they have stopped a cyberattack targeting a national online platform used by citizens to communicate with government offices. Digital Affairs Minister Krzysztof Gawkowski said on X on Tuesday evening that cybersecurity teams had taken immediate action to contain the attack and maintain the stability of the ePUAP system. "The infrastructure of the Central Informatics Center is secure, and the Internal Security Agency has been brought in to fully investigate the incident in accordance with established procedures," he added. The ePUAP platform allows people across Poland to submit official documents and applications online and sign them electronically using Trusted Profile, a government-backed digital identity system. The incident follows a series of cyberattacks on Polish public institutions, including a breach of a Culture Ministry digital system in October and a ransomware attack on a public hospital in the northwestern city of Szczecin in March. According to US tech giant Microsoft, Poland was among the ten countries most frequently targeted by Russian state-linked hacking groups between July 2025 and June 2026.
