UK Blames China for Massive Breach of Voter Data

The U.K. government has blamed China for a 2021 cyberattack that compromised the personal information of millions of U.K. voters. From a report: In a statement to lawmakers in Parliament on Monday, U.K. deputy prime minister Oliver Dowden attributed the 2021 data breach at the Electoral Commission to hackers working for the Chinese government. Dowden told lawmakers that the U.K. government 'will not hesitate to take swift and robust actions wherever the Chinese government threatens the United Kingdom's interests.'

It's the first time the United Kingdom has attributed the breach since the cyberattack was first disclosed in 2023. The Electoral Commission, which maintains copies of the U.K. register of citizens eligible to vote, said at the time hackers took the names and addresses of an estimated 40 million U.K. citizens, including those who were registered to vote between 2014 and 2022 and overseas voters. The data breach began as early as 2021 but wasn't detected until a year later. In a statement Monday, the U.K. National Cyber Security Centre (NCSC) said it is 'highly likely' that the Chinese hackers accessed and exfiltrated emails and data from the electoral register during the hack.
