Poland’s Nuclear Research Center Targeted by Hackers

Originally published on: March 17, 2026
▼ Summary

– Poland’s National Centre for Nuclear Research successfully blocked a cyberattack before it could compromise systems or disrupt operations.
– The attack did not affect the MARIA research reactor or any production, operational, or research processes.
– The institute is a major Central European research center focused on nuclear energy and subatomic physics.
– Following the attack, the center is collaborating with national cybersecurity authorities to analyze the incident and enhance protections.
– While no group claimed responsibility, Polish officials indicated early signs point to possible Iranian origins, though Poland is often targeted by Russian-linked actors.

Poland’s National Centre for Nuclear Research successfully defended its IT systems from a sophisticated cyber intrusion, ensuring no disruption to its critical scientific operations. The swift detection and response prevented any compromise of sensitive systems, highlighting the importance of robust cybersecurity for national research infrastructure.

The MARIA research reactor continues to operate safely at full capacity, with no impact on production, operational, or research activities, confirmed Professor Jakub Kupecki, the Centre’s Director. As one of Central Europe’s premier scientific institutions, the NCBJ is a vital hub for advanced studies in nuclear energy, subatomic physics, and related applied sciences.

Upon identifying the threat, the centre immediately coordinated with national cybersecurity agencies and other specialized services. This collaborative effort focused on a thorough forensic analysis of the incident and implementing enhanced defensive measures. Security teams and relevant authorities maintain continuous monitoring of the situation to safeguard the institute’s digital environment.

While no hacking group has formally taken credit for the attempt, preliminary findings from Polish officials suggest the activity may have originated from Iran. Poland has increasingly faced cyberattacks targeting its critical infrastructure in recent years, with numerous incidents previously linked to threat actors associated with Russia. This event underscores the persistent digital threats faced by vital scientific and energy facilities globally.
