Cyber Incident Victim: Maiden Erlegh Trust
Date:
Sep 2023
Location:
United Kingdom
Summary
Maiden Erlegh Trust experienced a sophisticated ransomware attack that temporarily disrupted network access across all its schools, prompting activation of business continuity plans and cyber security protocols. The incident, reported to law enforcement and regulatory bodies, required third-party forensic analysis to assess potential data risks and restore systems, though cloud-based platforms storing most personal data remained unaffected. The attack caused ongoing IT access challenges impacting school operations, consistent with broader trends targeting UK educational institutions due to their sensitive data and perceived vulnerabilities, as observed in concurrent incidents affecting other schools before the academic term.

Description
In September 2023, Maiden Erlegh Trust, a multi-academy trust operating schools in Berkshire, experienced a sophisticated ransomware attack that compromised its IT systems. An unauthorized third party gained access to the Trust’s network, encrypting data and rendering systems temporarily inaccessible. The Trust activated its business continuity plans immediately after detecting the intrusion, including predefined cybersecurity procedures to mitigate the incident. Preventative security protocols were in place prior to the attack, but the perpetrators circumvented these measures. The breach was reported to Thames Valley Police Cyber Unit, the Department for Education, the Trust’s Data Protection Officer, and the Information Commissioner’s Office (ICO). Containment efforts began promptly, involving the isolation and removal of malicious software, alongside initiating system restoration. Third-party cybersecurity specialists were engaged to conduct forensic analysis of the network, aiming to determine the attack’s origin, scope, and potential compromise of personal data. Critical cloud-based systems, including the Bromcom Management Information System storing most student and staff data, remained unaffected. The Trust emphasized its commitment to data security but acknowledged ongoing IT access challenges across its schools due to the meticulous restoration process.
The cyber-attack disrupted operational continuity, affecting over 1800 pupils and necessitating individualized recovery efforts at each school. Heads of schools were tasked with communicating specific impacts to parents, though no confirmed data breach had been identified during the initial forensic review. Restoration work prolonged system downtime, complicating administrative and educational activities at the start of the academic term. The incident aligned with a broader pattern of ransomware targeting UK educational institutions, which face heightened risks due to perceived vulnerabilities in cybersecurity infrastructure. Maiden Erlegh Trust’s reliance on external experts underscored the complexity of resolving such attacks while maintaining transparency with stakeholders through direct updates and a dedicated incident inquiry email address. Ongoing forensic investigations focused on quantifying data exposure risks and reinforcing system resilience against future threats.
