The fine relates to a ransomware incident in August 2022, which saw hackers access certain systems of Advanced's health and care subsidiary via a customer account that did not have multi-factor authentication (MFA). The cyber attack reportedly resulted in disruption to critical services such as NHS 111 and other healthcare staff unable to access patient records. 

The investigation found that personal information belonging to 79,404 people was taken, including details of how to gain entry into the homes of 890 people who were receiving care at home. 

The ICO's investigation concluded that Advanced's health and care subsidiary did not have the appropriate technical and organisational measures in place to keep its health and care systems fully secure prior to the 2022 incident – including gaps in the deployment of MFA, a lack of comprehensive vulnerability scanning and inadequate patch management. 

The ICO announced its provisional intention to fine Advanced £6.09m in August 2024, but reduced the fine after Advanced submitted representations on the decision. 

Several factors from these representations led to a reduction in the fine, including Advanced's proactive engagement with the National Cyber Security Centre, the National Crime Agency and the NHS in the wake of the attack and other steps taken to mitigate the risk to those impacted. 

The ICO and Advanced have now agreed a voluntary settlement, which will see Advanced pay a final penalty of £3.07m without appealing. 

John Edwards, information commissioner, said: 'The security measures of Advanced's subsidiary fell seriously short of what we would expect from an organisation processing such a large volume of sensitive information. While Advanced had installed multi-factor authentication across many of its systems, the lack of complete coverage meant hackers could gain access, putting thousands of people's sensitive personal information at risk. 

'People should never have to think twice about whether their medical records are in safe hands. To use services with confidence, they must be able to trust that every organisation coming into contact with their personal information – whether that's using it, sharing it or storing it on behalf of others – is meeting its legal obligations to protect it. 

'With cyber incidents increasing across all sectors, my decision today is a stark reminder that organisations risk becoming the next target without robust security measures in place. I urge all organisations to ensure that every external connection is secured with MFA today to protect the public and their personal information - there is no excuse for leaving any part of your system vulnerable.'
