The identities of more than 100 British officials, including members of the special forces and intelligence agency MI6, have been exposed in a significant data breach that also threatens the safety of thousands of Afghans. This incident puts Afghans at risk of retaliation from the Taliban, contributing to an ongoing humanitarian crisis in the region. The details of the leak, kept under wraps by a High Court injunction until this week, reveal that sensitive personal data was unintentionally shared as part of a database that housed case notes related to resettlement applicants.

The British government acknowledged on Tuesday that nearly 19,000 Afghans, who had collaborated with British forces during the two-decade-long conflict, had their information leaked. Many of these individuals are in danger of severe repercussions, including death, as Taliban forces actively seek to punish those who assisted Western military efforts.

The breach originated when an employee at the UK Special Forces headquarters mistakenly emailed over 30,000 resettlement applications to a person outside the government, misjudging the communication to involve only 150 cases. This accidental dissemination prompted the establishment of the Afghanistan Response Route (ARR), a covert scheme designed to facilitate the resettlement of affected individuals, which has already brought about 4,500 Afghans and their families to the UK. However, officials had failed to notify those at risk about the data leak throughout the process.

Following the release of the super-injunction, a secondary injunction restricted the reporting of information regarding the breach's implications for special forces personnel until recently. Debates in Parliament saw Defence Secretary John Healey label the leak as a "serious departmental error," recognizing it as an instance among many data losses affecting Afghan resettlement efforts. Meanwhile, shadow defence secretary James Cartlidge extended apologies on behalf of the previous Conservative administration, which was in power when the incident unfolded.

The Ministry of Defence (MoD) has opted not to disclose the number of individuals in Afghanistan who may face danger following the leak. Although the Taliban claims to have neither monitored nor detained the individuals named in the data breach, families of the affected Afghans report that Taliban efforts to locate them have increased. An MoD spokesperson reiterated the commitment to safeguarding personnel security, particularly those in sensitive roles, amid ongoing scrutiny.
