Washington: The Biden administration and its allies have formally accused China of the mass-hacking of Microsoft Exchange servers earlier this year, which prompted the FBI to intervene as concerns rose that the hacks could lead to widespread destruction.
The attack targeted Microsoft Exchange servers, affecting at least 30,000 organisations globally.
Western security services believe it signals a shift from a targeted espionage campaign to a smash-and-grab raid, leading to concerns Chinese cyber-behaviour is escalating.
The Chinese Ministry of State Security (MSS) has also been accused of wider espionage activity and a broader pattern of “reckless” behaviour.
China has previously denied allegations of hacking and says it opposes all forms of cyber-crime.
Several allies, including the U.K. and the members of NATO, also backed the Biden administration in its findings. In a statement, the U.K. government found Beijing responsible for a “pervasive pattern” of hacking. The Chinese government has repeatedly denied claims of state-backed or sponsored hacking.
The Biden administration also blamed China’s Ministry of State Security for contracting with criminal hackers to conduct unsanctioned operations, like ransomware attacks, “for their own personal profit.”
The statement also said that the China-backed hackers engaged in extortion and cryptojacking, a way of forcing a computer to run code that uses its computing resources to mine cryptocurrency for financial gain.
In response, a Chinese foreign ministry spokesperson accused the United States of “meddling” in its internal affairs.
