The hacking collective going by the name 'Parastoo' have claimed responsibility for the hack and have published over 150 email addresses on Pastebin. The hacking collective has noted in the post that the published emails are of those people who “help” the IAEA.
The hacking collective is claiming that despite the fact Israel is not allowed to build nuclear weapons, it is doing so at the Negev Nuclear Research Center near the city of Dimona. Parastoo has revealed that it is not linked with the hacking collective Anonymous and has warned that it will publish personal and professional information about people on the email list.
IAEA spokesperson Gill Tudor confirming the breach told Reuters "The IAEA deeply regrets this publication of information stolen from an old server that was shut down some time ago." Tudor said that security and technical teams over at IAEA are analyzing the situation and are working towards making sure that no other information is vulnerable.
"The IAEA's technical and security teams are continuing to analyze the situation and do everything possible to help ensure that no further information is vulnerable", added Tudor.
