Polish authorities announced Thursday they are investigating whether Iranian hackers are behind the attempted attack on a major nuclear research facility.  

The cyberattack unsuccessfully targeted the National Centre for Nuclear Research, which houses the country’s only operating nuclear reactor, officials said. Polish digital minister Krzysztof Gawkowski said that “the first identifications of the entry vectors … are related to Iran,” while cautioning that the signals could be deliberate misdirection to hide the criminals’ true location.
