( CNN ) -- Hackers using a server in China stole the blueprints for the new headquarters of Australia 's main spy agency `` some time ago , '' an opposition senator said Wednesday , contradicting comments by the country 's prime minister . The controversy stems from a TV report this week alleging that a cyberattack swiped the blueprints to the new headquarters of the ASIO , Australia 's top intelligence organization , including details on the building 's security and communications systems , its floor plan and the locations of its servers . `` These events did take place some time ago ; they were dealt with by ASIO , '' said George Brandis , the deputy leader of the opposition in the Senate who is responsible for national security issues . `` I 'm reassured by the director general about the way in which they were dealt with by ASIO . '' He was speaking in an interview with CNN affiliate Sky News Australia following a private briefing with David Irvine , the director-general of the spy agency . Prime Minister Julia Gillard on Tuesday described the report , by the Australian Broadcasting Corporation 's investigative program Four Corners , as `` inaccurate . '' The program also reported that hackers , thought to be from China , had breached government agencies including the prime minister 's office and cabinet , as well as the departments of foreign affairs and defense . `` There were a number of unsubstantiated allegations of hacking in the Four Corners report as the attorney general has stated , '' Gillard said in parliament . `` Neither he or the director general of ASIO intend to comment further on these inaccurate reports . '' But Brandis disputed Gillard 's statement . `` The prime minister in question time yesterday just dismissed the report entirely as being inaccurate , and that claim by the prime minister is false , '' he said . Gillard 's office did n't immediately respond to a request for comment on Brandis 's remarks . Brandis 's office did n't immediately make him available for further comment on the matter . Australia the 'lucky country ' for a better life : survey . At a foreign ministry news conference Tuesday , a Chinese government official called the report a `` baseless accusation . '' `` Since the attacks are technically untraceable , it 's difficult to find the origin of these attacks , '' said foreign ministry spokesman Hong Lei . `` I do n't know where does the evidence come from for media to make such reports . '' Hong added that cybersecurity is an issue internationally and it calls for a `` calm and thorough discussion . '' `` Making baseless accusation will not help to improve the current situation , '' he said . Earlier this month , the United States accused China of trying to extract sensitive information from U.S. government computers . A Pentagon report said China was carrying out the attacks in an effort to extract information from `` diplomatic , economic and defense industrial base sectors that support U.S. national defense programs . '' At the time , the Chinese Foreign Ministry said China was `` firmly against any forms of cyberattacks . '' Beijing has in the past insisted that China is the victim of cyberattacks , most originating in the United States . Watch where you click : International cyber attacks on the rise .
