The hack originated from a "previously unknown group critical of Israel's undeclared nuclear weapons program," according to the AP, which asked for an open investigation in Israel's nuclear activities. With the exception the names exposed and a request to sign a petition. the group called "Parastoo" apparently did not cause further damage.
The IAEA apologized for the hack and said that only one old server that was shut down a while ago was affected. Spokeswoman Gill Tudor said that work to close vulnerabilities had been done to the server prior to the hack and the agency is now doing "everything possible to help ensure that no further information is vulnerable."
