A significant data leak in Afghanistan, exposing sensitive information about Afghan citizens, has triggered a large-scale, clandestine evacuation effort. The BBC's security correspondent, Frank Gardner, is examining the implications of this breach. His analysis focuses on three central questions: What specific data was compromised? What are the immediate and long-term security risks to those affected? And what failures in data protection led to this critical vulnerability? The answers to these questions are crucial for understanding the scope of the crisis and preventing future occurrences.
