The UK’s Electoral Commission revealed that a cyber attack granted access to the data of 40 million voters. It went unnoticed for a year and was not disclosed to the public for an additional 10 months. The Guardian reports: The Electoral Commission apologized for the security breach in which the names and addresses of all voters registered between 2014 and 2022 were open to “hostile actors” as far back as August 2021. The attack was discovered last October and reported within 72 hours to the Information Commissioner’s Office (ICO), as well as the National Crime Agency. However, the public has only now been informed that the electoral registers containing the data of millions of voters may have been accessible throughout that time.
The Electoral Commission said it was “not able to know conclusively” what information had been accessed. It is not known whether the attackers were linked to a hostile state, such as Russia, or a criminal cyber gang. The watchdog said “much of the data” was already in the public domain and insisted it would be difficult for anyone to influence the outcome of the UK’s largely paper-based electoral system, but it acknowledged that voters would still be concerned.
The attackers were able to access full copies of the electoral registers, held by the commission for research purposes and to enable permissibility checks on political donations. These registers include the name and address of anyone in the UK who was registered to vote between 2014 and 2022. The commission’s email system was also accessible during the attack. The full register held by the Electoral Commission contains name and address data that can be inspected by the public but only locally through electoral registration officers, with only handwritten notes allowed. The information is not permitted to be used for commercial or marketing purposes. The data of anonymous voters whose details are private for safety reasons and the addresses of overseas voters were not accessible to the intruders in the IT system. A spokesperson for the ICO, the UK’s independent regulator on data protection, said: “The Electoral Commission has contacted us regarding this incident and we are currently making inquiries.”
They added: “We recognize this news may cause alarm to those who are worried they may be affected and we want to reassure the public that we are investigating as a matter of urgency. In the meantime, if anyone is concerned about how their data has been handled, they should get in touch with the ICO or check our website for advice and support.”
