Dozens of Afghans whose personal information was exposed in a British Ministry of Defence (MoD) data breach have reported that their relatives or colleagues were killed because of the leak, according to new research submitted to a UK parliamentary inquiry. The breach, which occurred in February 2022, revealed the identities of nearly 19,000 Afghans who had worked with the UK government during the war in Afghanistan. It happened just six months after the Taliban regained control of Kabul, leaving many of those listed in grave danger.
The study, conducted by Refugee Legal Support in partnership with Lancaster University and the University of York, surveyed 350 individuals affected by the breach. Of those, 231 said the MoD had directly informed them that their data had been compromised. Nearly 50 respondents said their family members or colleagues were killed as a result, while over 40 percent reported receiving death threats. At least half said their relatives or friends had been targeted by the Taliban following the exposure of their details.
One participant, a former Afghan special forces member, described how his family suffered extreme violence after the leak. “My father was brutally beaten until his toenails were torn off, and my parents remain under constant threat,” he said, adding that his family continues to face harassment and repeated house searches. Others criticized the British government for waiting too long to alert them, saying the delay had endangered lives unnecessarily.
According to several accounts, while the MoD discovered the breach in 2023, many affected Afghans were only notified in mid-2025. “Waiting nearly two years to learn that our personal data was exposed placed many of us in serious jeopardy,” said a former Afghan National Army officer still living in Afghanistan. “If we had been told sooner, we could have taken steps to protect our families.”
Olivia Clark, Executive Director of Refugee Legal Support, said the findings revealed the “devastating human consequences” of the government’s failure to protect sensitive information. “Afghans who risked their lives working alongside British forces have faced renewed threats, violent assaults, and even killings of their loved ones after their identities were exposed,” she said.
Clark added that only a small portion of those affected have been offered relocation to the UK. The government estimates that more than 7,300 Afghans qualify for resettlement under a program launched in 2024 to assist those placed at risk by the data breach. However, rights organizations say the scheme has been too slow and insufficient compared to the magnitude of the crisis.
The breach has raised significant concerns about how the UK manages sensitive defense data and its responsibilities toward Afghans who supported British missions. For many of those affected, the consequences of the exposure remain deeply personal and ongoing, with families still living under threat while waiting for promised protection or safe passage to the UK.
