Ministry of Defence (UK)

Ministry of Defence (UK)

The UK Ministry of Defence (MoD) suffered a catastrophic data breach involving the accidental disclosure of sensitive personal details of **18,700 Afghan nationals**—including those who had worked with British forces—via misdirected emails to unrelated recipients, such as the **Civil Service Sports & Social Club** (140,000 members). The leaked spreadsheets contained contact information, relocation statuses, and other critical data under the **Afghan Relocations and Assistance Policy (ARAP)**. At least **49 individuals** are believed to have been killed as a direct result of the exposure, with their identities potentially falling into the hands of the Taliban or other hostile actors. Additional breaches included **unsecured WhatsApp sharing of personal data**, **flight manifests of Afghan evacuees**, and an official’s laptop left open on a train. The scandal was **covered up for years** before legal action by *The Independent* forced disclosure. The MoD’s permanent secretary resigned amid criticism of systemic failures, including employees’ ignorance of basic data-handling protocols (e.g., hidden Excel tabs). The breaches underscore **life-threatening consequences** for vulnerable allies and raise grave concerns about the UK government’s ability to safeguard classified or sensitive information in an era of escalating cyber and human-error risks.
