Glasgow City Council is the latest local authority to fall victim to a significant cyber attack that has disrupted numerous online services and potentially compromised customer data. The incident, discovered on 19th June 2025, was identified when the council's ICT supplier CGI detected malicious activity on servers managed by a third-party provider.
The attack has forced the council to take affected servers offline as a precautionary measure, causing widespread disruption to digital services including planning applications, parking penalty payments, school absence reporting, and pension portal access. Whilst the council cannot yet confirm whether data has been stolen, they are operating under the assumption that customer information from affected web forms may have been compromised. Council officials have reassured residents that no financial systems were affected and no banking details have been compromised.
This incident adds to a concerning pattern of cyber attacks targeting public sector organisations over the past 18 months. Leicester City Council suffered a critical ransomware attack in March 2024, with the Inc Ransom group subsequently publishing confidential data online after demands weren't met (See - Leicester City Council hit by cyber attack). In August 2024, housing software provider Locata was targeted, affecting Manchester, Salford, and Bolton councils' housing websites and exposing thousands of users to phishing emails. In January this year, Gateshead council was targeted by the Medusa ransomware group, with numerous types of data compromised (See - Gateshead latest council to be hit by cyber attack). We also saw numerous DDoS attacks against UK councils including Portsmouth, Bradford, Salford, and Plymouth, temporarily disabling their websites.
The investigation into the attack on Glasgow continues, with support from Police Scotland, the Scottish Cyber Coordination Centre, and the National Cyber Security Centre, as the Council works to restore normal operations.
