SBI reports suspected exposure of customer data on the dark web

SBI noted that a detailed investigation was required to establish the authenticity and completeness of the exposed data, determine the potential source and extent of the exposure, and assess the associated risks to customers and the Bank.

“We wish to submit that this does not have any material impact on Bank’s Core business operations, financial performance or business continuity. The Bank’s core business functions continue to operate normally without disruptions,” the Bank said.

A detailed assessment is currently underway and appropriate remedial and preventive measures are being implemented as required, it added. ,
