The Information Commissioner’s Office has fired a warning shot over the bows of all tech providers which handle personal data on behalf of their clients after threatening a £6m fine against a company which has been blamed for the major NHS ransomware attack during the summer of 2022.
The regulator has published an inital finding that Advanced Computer Software Group failed to implement measures to protect the personal information of 82,946 people, including some sensitive data.
Advanced provides IT and software services to organisations on a national scale, including the NHS and other healthcare providers, and handles people’s personal information on behalf of these organisations as their data processor.
The provisional decision to issue a fine relates to a ransomware incident in August 2022, where the ICO has provisionally found hackers initially accessed a number of Advanced’s health and care systems via a customer account that did not have multi-factor authentication.
The cyber attack was widely reported at the time of the incident, with disruption to critical services such as NHS 111, and other healthcare staff unable to access patient records.
The data exfiltrated included phone numbers and medical records, as well as details of how to gain entry to the homes of 890 people who were receiving care at home. People impacted have been notified, and Advanced found no evidence that any data was published on the dark web.
Data processors act on the instructions of their clients, the data controllers, who have overall control over how and why personal information is used.
However, the ICO is keen to point out that data processors still have their own obligations to implement appropriate technical and organisational measures to ensure personal information is kept secure. This includes taking steps to assess and mitigate risks, such as regularly checking for vulnerabilities, implementing multi-factor authentication and keeping systems up to date with the latest security patches.
Commissioner John Edwards has stressed that the findings are provisional, adding that no conclusion should be drawn at this stage that there has, in fact, been any breach of data protection law or that a financial penalty will ultimately be imposed.
He confirmed he will consider any representations from Advanced before making a final decision, with the fine amount also subject to change.
Edwards said: “This incident shows just how important it is to prioritise information security. Losing control of sensitive personal information will have been distressing for people who had no choice but to put their trust in health and care organisations.
“Not only was personal information compromised, but we have also seen reports that this incident caused disruption to some health services, disrupting their ability to deliver patient care. A sector already under pressure was put under further strain due to this incident.
“For an organisation trusted to handle a significant volume of sensitive and special category data, we have provisionally found serious failings in its approach to information security prior to this incident.
“Despite already installing measures on its corporate systems, our provisional finding is that Advanced failed to keep its healthcare systems secure. We expect all organisations to take fundamental steps to secure their systems, such as regularly checking for vulnerabilities, implementing multi-factor authentication and keeping systems up to date with the latest security patches.
“I am choosing to publicise this provisional decision today as it is my duty to ensure other organisations have information that can help them to secure their systems and avoid similar incidents in the future. I urge all organisations, especially those handling sensitive health data, to urgently secure external connections with multi-factor authentication.”
