A massive data breach has exposed 273,000 sensitive banking documents from 38 Indian financial institutions, discovered by UpGuard researchers on an unsecured Amazon cloud server. The files included account numbers and transaction details, with over half linked to Aye Finance, which aimed for a $171 million IPO. Despite prompt notices to responsible parties, including the NPCI, no one accepted responsibility. The incident underscores significant cybersecurity accountability gaps in India's rapidly digitizing financial sector.
