A hacker has allegedly stolen a massive trove of sensitive data – including highly classified defense documents and missile schematics – from a state-run Chinese supercomputer in what could potentially constitute the largest known heist of data from China. CNN has reached out to China’s Ministry of Science and Technology as well as the Cyberspace Administration of China for comment. The swath of samples that the sellers put out kind of really speaks to the breadth of customers that this supercomputing center had,” Cary said. The attacker claimed to have gained access to the Tianjin supercomputer through a compromised VPN domain. Staff members walk past the Tianhe-1 supercomputer at the National Supercomputing Center in Tianjin, China, on November 2, 2010.
