By Ry Crozier on Apr 21, 2021 11:36PM Fed thousands of customers' details into analysis services. NAB has revealed that it terminated the contract of a technology staffer that ran thousands of customers’ details through tools offered by a pair of data service companies back in mid-2019. The data breach, disclosed on a Friday evening in July 2019, saw the personal details of 13,000 customers - later revised down to 11,500 - uploaded to the online data services in an analytics exercise gone wrong. In new details about the breach revealed last week, NAB said “the unauthorised upload was detected and triggered alerts in NAB systems, and an investigation into the event was immediately commenced.”
