The Labour party has experienced a “sophisticated and large-scale cyber-attack” on its digital systems from an unknown source, it has said, adding that it is confident its security systems ensured there was no data breach.
Party officials have reported the attack, which took place on Monday, to the National Cyber Security Centre, the government agency that supports and advises organisations on such incidents.
Labour has not said which digital platforms were targeted, but it is understood some of them were election and campaigning tools, which would contain details about voters. The party has sent a message to campaigners to say what happened, and to explain why the systems were working slowly on Monday.
A party spokeswoman said: “We have experienced a sophisticated and large-scale cyber-attack on Labour digital platforms. We took swift action and these attempts failed due to our robust security systems. The integrity of all our platforms was maintained and we are confident that no data breach occurred.
“Our security procedures have slowed down some of our campaign activities, but these were restored this morning and we are back up to full speed. We have reported the matter to the National Cyber Security Centre.”
