Poland’s National Centre for Nuclear Research Thwarts Cyberattack on IT Infrastructure Poland’s National Centre for Nuclear Research (NCBJ) successfully blocked a cyberattack targeting its IT systems before any disruption occurred. The incident, detected and neutralized by security teams, posed no threat to the institute’s operations, including the safe and uninterrupted function of the MARIA research reactor, which continues to operate at full capacity. The NCBJ, a leading scientific institute in Central Europe, specializes in nuclear energy, subatomic physics, and applied research. Following the attempted intrusion, the centre collaborated with national cybersecurity authorities to investigate the attack and reinforce its defenses. While no group has claimed responsibility, Polish officials indicated early evidence suggests possible links to Iran. Poland has faced a rising number of cyber threats against critical infrastructure in recent years, with many attacks attributed to state-linked actors, particularly those associated with Russia. The NCBJ confirmed that monitoring efforts remain ongoing as authorities assess the incident’s origins and implications.
