London’s Hackney Council has revealed it was hit by a cyber attack that exfiltrated personal information on residents including names, addresses, racial or ethnic origins, religious beliefs, sexual orientations, health data, economic details and criminal records.
In total, 440,000 files were accessed and encrypted, affecting 280,000 residents (via CityAM).
The Information Commissioner's Office (ICO) recently completed its investigation into the attack, with the ICO’s deputy commissioner Stephen Bonner stating “This was a clear and avoidable error from London Borough of Hackney, one that has resulted in a mass loss of data and has had a severely detrimental impact on many residents.”
Avoidable cyber attack
“At its absolute worst, this has meant that some of the most deeply personal information possible has ended up in the hands of the attackers," Bonner added. "Systems that people rely on were offline for many months. This is entirely unacceptable and should not have happened.”
“If we want people to have trust in local authorities, they need to trust that local authorities will look after their data properly. Hackney residents have learnt the hard way the consequences for these errors – councils across the country should act now to ensure that those they are responsible for do not suffer the same fate,” Bonner concluded.
In total, the ICO reported that over 9,6000 resident records were confirmed as being successfully taken by the attackers.
A statement from Hackney Council said, “While we welcome the ICO completing its investigation, we maintain that the Council has not breached its security obligations. We consider that the ICO has misunderstood the facts and misapplied the law with respect to the issues in question, and has mischaracterised and exaggerated the risk to residents’ data.”
“However, we do not believe it is in our residents’ interests to use our limited resources to challenge the ICO’s decision. We have worked closely with the National Cyber Security Centre, National Crime Agency and Metropolitan Police to identify, contact and help those who were significantly affected by the cyberattack, and the ICO has recognised our robust and transparent response,” the statement added.
