More than 200 cooperative and regional rural banks were briefly cut off from India's retail payments system last week by the National Payments Corporation of India (NPCI) amid concerns that C-Edge Technologies had been hit by a ransomware attack.
In a statement, NPCI said core banking vendor C-Edge had "possibly" had its systems affected by a ransomware attack.
"To prevent larger impact to the payment ecosystem, NPCI has temporarily isolated C-Edge Technologies from accessing the retail payment systems operated by NPCI. Customers of banks serviced by C-Edge will not be able to access payment systems during the period of isolation."
Connectivity was reestablished the following day following a review by an independent forensic auditing firm, which found that the impact was limited to C-Edge systems hosted in its data centre and did not touch any bank infrastructure.
