Prime Minister John Key last night confirmed that an attempt to hack into a supercomputer at the National Institute of Water and Atmospheric Research (Niwa), was from an IP address in China.
But he cautioned against assuming it was part of the state-sponsored hacking from China that the United States has decided to publicly target.
He said the IP address in the case of Niwa, a Crown Research Institute, was from China, "although that doesn't mean at all that it is from a Chinese entity".
"They often masquerade behind a particular IP address but that doesn't mean that is the ultimate source of the attack," he said at his post-cabinet press conference.
Attempts to hack into the computer, dubbed FitzRoy, were unsuccessful, Niwa said yesterday.
