On 31 July, the National Payments Corporation of India (NPCI) issued a press release notifying that C-Edge Technologies Ltd, a technology service provider set up as a joint venture between Tata Consultancy Services Ltd and State Bank of India, was attacked using sophisticated ransomware. NPCI temporarily isolated C-Edge Technologies from accessing the retail payment systems operated by NPCI but restored connectivity the next day following a security review by an independent forensic auditing firm.

The investigation confirmed the isolation of the affected systems by C-Edge to contain the potential spread of the ransomware and the auditor also conducted additional security reviews and scans to certify that the rest of the infrastructure was clean.
