Unsecured Cloud Server Exposes Hundreds of Thousands of Bank Transfer Records
In a significant data security incident, cybersecurity firm UpGuard discovered an unsecured Amazon-hosted cloud storage server containing over 273,000 PDF documents related to Indian bank transfers. The files detailed sensitive financial information including account numbers, transaction amounts, and contact details of individuals. These documents pertain to transactions processed via the National Automated Clearing House (NACH), a centralized Indian banking system used for high-volume recurring payments such as salaries, loan repayments, and utility bills.
Scope of Exposure: Multiple Banks and Financial Institutions Involved
The exposed data was linked to at least 38 banks and financial institutions across India. Among the most frequently mentioned entities in a sample of 55,000 documents were Aye Finance, an Indian lender that recently filed for a $171 million IPO, and the State Bank of India, the country’s largest state-owned bank.
Discovery and Notification Efforts by UpGuard
UpGuard’s researchers uncovered the exposed data in late August and promptly alerted Aye Finance via multiple corporate communication channels, as well as the National Payments Corporation of India (NPCI), which oversees the NACH system. Despite these notifications, the data remained publicly accessible into early September, with thousands of new files being added daily. UpGuard escalated the issue to India’s Computer Emergency Response Team (CERT-In), after which the data was secured.
Lack of Accountability and Conflicting Statements
Responsibility for the breach remains unclear. NPCI denied that any data from its systems had been compromised, stating in a formal communication that their NACH mandate records were not exposed. Attempts to obtain comments from Aye Finance and the State Bank of India were unsuccessful, with both entities remaining silent on the matter.
Implications for Data Security in Indian Banking
This incident highlights persistent vulnerabilities in cloud data management and the critical need for stringent security protocols. With sensitive personal and financial information at risk, the breach underscores the potential for fraud, identity theft, and reputational damage to affected institutions. Furthermore, the absence of clear accountability raises questions about regulatory oversight and the efficiency of response mechanisms in India’s digital banking infrastructure.
