NSW Treasury Insider Breach – 5,600 Sensitive Documents Exfiltrated
Published 6 months, 2 weeks ago
Description
In April 2026, NSW Treasury disclosed a significant insider data breach: a staffer on its commercial team allegedly exfiltrated more than 5,600 sensitive government documents to an external server. In this episode of Tech Talks with Kinsoft, we cover how internal security monitoring flagged the suspicious transfer, the involvement of NSW Police, the arrest and charges, the confidential commercial and financial information involved, and the government's coordinated response — including that the data was recovered and public services were not disrupted.
