Chinese diplomats branded the allegation ‘groundless and irresponsible’ on Tuesday while dubbing Washington ‘the world champion of malicious cyber attacks’.
America made the allegations after a hack of Microsoft Exchange servers in January that affected some 30,000 organisations worldwide including defence contractors and think-tanks.
He added that US intelligence is carrying out an investigation into the hack, which affected at least 30,000 businesses, and may take action once it is completed.

US Secretary of State Antony Blinken said the attack on Microsoft Exchange, a top email server for corporations around the world, was part of a ‘pattern of irresponsible, disruptive and destabilizing behavior in cyberspace, which poses a major threat to our economic and national security.’
China’s Ministry of State Security, or MSS, ‘has fostered an ecosystem of criminal contract hackers who carry out both state-sponsored activities and cybercrime for their own financial gain,’ Blinken said in a statement.
In a simultaneous announcement, the US Department of Justice said four Chinese nationals had been charged with hacking the computers of dozens of companies, universities and government bodies between 2011 and 2018.
The statement also singled out a hack of Microsoft Exchange servers that began in January this year and affected at least 30,000 organisations worldwide.
A group known as Hafnium is believed to have identified a weakness in the servers in January, and begun inserting ‘backdoors’ into systems using them which they could return to later, the BBC reported.
The operation targeted defence contractors, think tanks and universities, and appears to have initially been aimed at surveilliance and covert data-gathering.
But in February the operation massively expanded into a ‘smash and grab’ raid on the servers after several other hacking groups piled in.
It is thought Hafnium became aware that Microsoft had identified the vulnerability they were exploiting and planned to close it, prompting them to share its existence and causing the pile-on.
Joe Biden said China (President Xi Jinping, right) may not be directly responsible for the hacks but, like Russia, is harbouring those who are carrying them out
Pointing to the indictment, Blinken said the United States ‘will impose consequences on (Chinese) malicious cyber actors for their irresponsible behavior in cyberspace.’
In a step the Biden administration hailed as unprecedented, the United States coordinated its statement Monday with allies – the European Union, Britain, Australia, Canada, New Zealand, Japan and NATO.
The Chinese embassy in New Zealand issued a swift rebuttal of the ‘totally groundless and irresponsible’ allegations.
It was backed up by the embassy in Australia, as China took a coordinated stance of its own, accusing Canberra of ‘parroting the rhetoric of the US.’
‘It is well known that the US has engaged in unscrupulous, massive and indiscriminate eavesdropping on many countries including its allies,’ the embassy said in a statement.
‘It is the world champion of malicious cyber attacks.’
Biden, like his predecessor Donald Trump, has ramped up pressure on China, seeing the rising Asian power’s increasingly assertive moves at home and abroad as the main long-term threat to the United States.
Allies backed up the castigation of China with British Foreign Secretary Dominic Raab describing the cyberattack as ‘reckless.’
NATO offered ‘solidarity’ over the Microsoft hacking without directly assigning blame, while noting that allies United States, Britain and Canada found China to be responsible.
State Department spokesman Ned Price said it was the first time NATO – the military alliance whose members include Hungary and Turkey, which have comparatively cordial relations with Beijing – has condemned cyber activity from China.
The Microsoft hack was carried out by the Hafnium group which used a vulnerability in servers to spy on organisations, before a mass pile-on when details of the ‘back door’ were shared
It comes weeks after NATO took up China at a summit attended by Biden.
‘We know we’ll be stronger, we know we’ll be more effective when we act collectively,’ Price said, saying the United States was not ruling out further action.
Biden has promised a strategy driven by alliances to face Beijing, drawing a contrast with Trump’s predilection for harsh rhetoric.
Frank Cilluffo, director of Auburn University’s McCrary Institute for Cyber and Critical Infrastructure Security, praised the ‘breadth and depth of international cooperation’ in clearly attributing responsibility to China.
‘In addition to the indictments, we need to follow through to ensure there are consequences to induce changes in the Chinese government’s behavior and hopefully move toward leveling the cyber playing field,’ he said.
The Microsoft hack, which exploited flaws in the Microsoft Exchange service, affected at least 30,000 US organizations including local governments as well as organizations worldwide.
‘Responsible states do not indiscriminately compromise global network security nor knowingly harbor cyber criminals – let alone sponsor or collaborate with them,’ Blinken said in his statement.
‘These contract hackers cost governments and businesses billions of dollars in stolen intellectual property, ransom payments, and cybersecurity mitigation efforts, all while the MSS had them on its payroll.’
Accusations of cyberattacks against the United States have recently focused on Russia, rather than China.
US officials say that many of the attacks originate in Russia, although they have debated to what extent there is state involvement. Russia denies responsibility.
This year has seen a slew of prominent ransomware strikes that have disrupted a major US pipeline, a meat processor and the software firm Kaseya, which affected 1,500 businesses.
Last week, Washington offered $10 million for information about foreign online extortionists.
