The Labour Party had suffered security incident following a cyber-attack on cloud computing provider Blackbaud. Hackers had accessed information about thousands of party donors over a period of several years. Personal and confidential information about donors, including analysis that was run by the party about their personal views, had been accessed. All donors, including those who donated less than £7,500 and therefore did not have to declare their donation to the Electoral Commission, had their data breached.

The Labour Party’s campaign website has suffered a “sophisticated and large-scale” cyber attack. Security procedures slowed down some election campaign activities, but the party believes that no sensitive data was compromised. The party said that the integrity of all their platforms was maintained and they are confident that no data breach occurred. Subsequent reports suggest it was a DDoS, the Labour Party might therefore want to hold off on praising its “robust security systems” for preventing a data breach.
