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.

'description': 'A series of data breaches within the UK Ministry of Defence '
'(MoD) and civil service resulted in the inadvertent '
'disclosure of sensitive personal data of at least 18,700 '
'Afghan nationals seeking asylum under the Afghan Relocations '
'and Assistance Policy (ARAP) and predecessor schemes. The '
'breaches included emails sent to unintended recipients (e.g., '
'the Civil Service Sports & Social Club), unsecured laptops '
'left on trains, insecure WhatsApp sharing, and exposed flight '
'manifests. The leaks reportedly led to fatal consequences for '
'some Afghans, with research suggesting 49 deaths may have '
'resulted. The scandal was initially covered up but later '
'exposed by *The Independent* after persistent lobbying and '
'legal action. Additional breaches included 49 incidents at '
'the MoD, highlighting systemic failures in data handling, '
'including a lack of understanding of basic Excel '
'functionalities (e.g., hidden tabs). The breaches were part '
'of a broader pattern of poor data security practices in UK '
'government agencies, with historical precedents such as the '
'2007 HMRC data loss affecting 25 million individuals.',
