Reporting on the leak
Several news organizations and journalists were granted early access and worked together for the past year to analyze the files, focusing on non-code documents. Their reporting covers the export of Geedge Networks’ censorship systems to Pakistan, Myanmar, Ethiopia, and Kazakhstan, focusing on human-rights impacts, procurement networks, and the spread of Great Firewall–style controls.
