In 2022, the UK’s **Ministry of Defence (MOD)** suffered a severe **data breach** involving the accidental leak of personal details of **~19,000 Afghan citizens** seeking refuge in the UK post-Taliban takeover. The breach occurred due to **insecure handling of Excel spreadsheets on a SharePoint site**, exposing sensitive information that led to **49 confirmed deaths** (linked to Taliban reprisals) and placed thousands more at risk. The incident, concealed under a superinjunction until 2024, has incurred an estimated **£850 million in costs** (excluding legal/compensation claims, which could push totals into **billions**). The **Public Accounts Committee (PAC)** criticized the MOD for **systemic failures**, including outdated IT infrastructure, lack of cybersecurity specialists, and repeated breaches (e.g., a 2023 leak of military personnel data). The breach’s fallout includes **operational disruptions**, reputational damage, and potential long-term geopolitical consequences, as compromised Afghans included interpreters and allies critical to UK missions. The PAC demanded urgent reforms, including **modernized systems** and **enhanced recruitment of digital security experts** to prevent future incidents.
