Oxford City Council cyberattack exposes 21 years of election data
20/06/2025 | The Register
Oxford City Council has confirmed that a cyberattack occurring over the weekend of 7-8 June compromised 21 years of historical data from its legacy systems. The breach primarily affected the personal information of individuals involved in council-administered elections between 2001 and 2022, with the majority of those affected believed to be current or former council officers.
In a statement, the council said there is no evidence of data being shared with third parties or a mass download, but investigations are ongoing to identify precisely what was accessed. Affected individuals have been contacted and offered support. While the council's automated security systems detected and stopped the attack, key services were temporarily shut down for cleanup by external cybersecurity experts. Most services are now restored and safe to use, though some technical issues persist.
