Hacking Attempt Reported at Poland’s Nuclear Research Center

Hacking attempts targeted Poland’s National Centre for Nuclear Research (NCBJ) and were described as thwarted, with no compromise of IT systems or disruption to MARIA reactor operations. In a statement, NCBJ said the attack was recent but that there was no impact on production, operations or research.

There is speculation about the origin: according to Deputy Prime Minister and Minister of Digital Affairs Krzysztof Gawkowski, early indicators point to Iran, though he cautioned that the evidence could have been planted to mislead investigators. The article notes that Poland’s nuclear research centre supports the civilian nuclear power programme but does not engage in military activities, and reiterates that Poland does not have a nuclear weapons programme.

The incident follows a separate cyberattack roughly two months earlier on Poland’s power grid, which was attributed to a Russian group and caused permanent damage to some ICS, but no electrical outages occurred. The report was written by Eduard Kovacs for SecurityWeek on 16 March 2026.
