The National Payments Corporation of India (NPCI) re-established the retail payment connections of banks that were using C-Edge systems on August 1 after the technology provider was hit by a ransomware attack, according to a statement from NPCI.

An investigation by NPCI confirmed ransomware on C-Edge and the impacted systems were isolated to ”contain potential spread” said the organisation. “Necessary security review and scans have been conducted by the auditor to ensure the rest of the infrastructure is clean” NCPI added.
