Western nations have accused China of carrying out a major cyber attack earlier this year.
The attack targeted Microsoft’s email servers and affected at least 30,000 companies worldwide.
Britain blamed government-backed Chinese actors for the attack, while the EU said the attack came from “Chinese territory”.
China’s foreign ministry has also been accused of widespread espionage and widespread “irresponsible” behavior.
China has previously denied hacking allegations and said it opposes all forms of cybercrime.
This united stand on the part of the European Union, the United States and Britain towards Beijing indicates the seriousness with which this issue has been resolved. Intelligence officials in Western countries say the features of the case are more serious than they have ever seen.
Hackers used a vulnerability in the email service, which allowed it to infiltrate further.
Britain has said the attack could lead to large-scale espionage operations, including access to personal information.
The vulnerabilities used by the Chinese group were exploited by other hacking groups, making the systems vulnerable to ransomware and spyware attacks.
The UK National Cyber Security Center has provided customized advice to more than 70 affected companies.
British Foreign Secretary Dominic Robb said cyber-attacks by pro-Chinese actors on Microsoft’s servers were an irresponsible, but habitual behavior from them.
“The Chinese government should end this formal cyber bullying and expect to be held accountable if it does not do so,” he added.
Western governments accuse China’s state defense ministry of using hired hackers and wanting to cut ties with them.
In a statement, the White House said it was “deeply concerned” that “China” was funding an intelligence agency, including hackers, that was conducting unrecognized cyber activities around the world, including their personal gain.
Meanwhile, the EU said the hack “led to security risks and significant economic losses for our state-owned enterprises and private companies.”
It also saw other similar Chinese behavior in a statement issued by the union. He has been linked to two groups believed to be linked to China’s foreign ministry.
Despite all these strong statements, there are no sanctions against China.
Microsoft announced the details of the hack in March, and said the Hafnium group affiliated with China was to blame. But China has denied the allegations.
The widespread use of Microsoft’s email program has made it vulnerable to many businesses and organizations that require significant effort to mitigate potential risks.
Meanwhile, the US Justice Department has announced criminal charges against four hackers from China’s Foreign Ministry, claiming it was linked to a long-running campaign targeting foreign governments and companies in key sectors in more than a dozen countries.
