New submitter ElectronF sends news that officials within the Australian government are blaming China for an attack on computer systems at the Bureau of Meteorology. "The bureau owns one of Australia's largest supercomputers and provides critical information to a host of agencies. Its systems straddle the nation, including one link into the Department of Defence at Russell Offices in Canberra." China has denied involvement, saying, "We have stressed that cyber security needs to be based on mutual respect. We believe it is not constructive to make groundless accusations or speculation." The Bureau's systems are still fully operational, though officials say the breach will require significant investment to recover from.
