Overview

• The Information Commissioner's Office (ICO) reprimanded Hackney Council for failing to implement adequate security measures.
• Hackers accessed and encrypted 440,000 files, including sensitive personal data, and deleted 10% of the borough's backups.
• The attack disrupted council services for months, with some systems not fully operational until 2022.
• Hackney Council disputes the ICO's findings but will not challenge the decision, focusing instead on improving data security.
• The ICO emphasized the need for councils to update systems and prevent human errors to protect residents' data.
