According to TechCrunch, Indian automotive giant Tata Motors fixed critical security flaws in its E-Dukaan e-commerce portal that exposed sensitive internal data including customer personal information, company reports, and dealer data. Security researcher Eaton Zveare discovered the vulnerabilities in August 2023, finding that the portal’s web source code contained private AWS keys that provided access to hundreds of thousands of invoices containing customer names, addresses, and permanent account numbers (PAN), along with 70 terabytes of fleet-tracking data and backdoor admin access to a Tableau account with over 8,000 users. Tata Motors confirmed through communications head Sudeep Bhalla that all reported flaws were “promptly and fully addressed” in 2023, though the company wouldn’t specify when fixes were completed or whether affected customers were notified about the data exposure. This incident highlights the persistent challenges in enterprise cloud security.

The Broader Cloud Security Implications
This Tata Motors incident represents a classic case of cloud misconfiguration that’s becoming increasingly common across enterprise environments. The exposure of AWS private keys in web source code suggests inadequate implementation of security best practices around secret management. Many organizations transitioning to cloud infrastructure struggle with the shared responsibility model, where cloud providers secure the infrastructure while customers must properly configure their applications and access controls. The scale of exposure—70 terabytes of data and access to multiple business systems—indicates that these weren’t isolated flaws but rather systemic security gaps in how Tata Motors managed its digital transformation across its global operations spanning 125 countries.
Customer Data Protection Failures
The exposure of PAN numbers represents one of the most serious aspects of this breach, given that India’s Permanent Account Number serves as a universal identifier for financial and tax purposes. Unlike credit card numbers that can be changed, PAN numbers are permanent identifiers that could enable identity theft and financial fraud for years to come. The presence of this sensitive data in what appears to be development or testing environments—given the researcher’s discovery of MySQL database backups and Apache Parquet files—suggests inadequate data classification and protection protocols. Companies operating in India must comply with the Digital Personal Data Protection Act, 2023, which mandates strict safeguards for personal data and requires breach notifications to both authorities and affected individuals.
Supply Chain and Dealer Network Vulnerabilities
The exposure of dealer scorecards and performance reports through the compromised Tableau account reveals another dimension of this security failure. Automotive manufacturers like Tata Motors operate complex supply chain and dealer networks where sensitive business intelligence could provide competitors with strategic advantages. The researcher’s access to Tata Motors’ FleetEdge platform and Azuga fleet management API could have enabled manipulation of vehicle tracking systems or unauthorized access to commercial fleet operations. This highlights how interconnected modern automotive ecosystems have become, where a single vulnerability in one system like the E-Dukaan spare parts portal can cascade across multiple business units.
Automotive Industry Security Challenges
This incident reflects broader security challenges facing the automotive industry as vehicles become increasingly connected and manufacturers transform into mobility service providers. Traditional automotive companies often struggle with cybersecurity maturity compared to technology-native organizations, particularly when integrating legacy systems with modern cloud platforms. The researcher’s decision to avoid “massive egress bills” by limiting data downloads reveals another concern—the financial impact of cloud security failures can extend beyond data exposure to include substantial operational costs. As detailed in the researcher’s technical analysis, the combination of exposed credentials and improperly configured access controls created a perfect storm of vulnerabilities that could have been exploited by malicious actors.
Regulatory and Compliance Questions
Tata Motors’ statement that they “maintain comprehensive access logs to monitor for unauthorized activity” raises questions about why these exposures weren’t detected internally before the external researcher’s discovery. The eight-month gap between initial reporting in August 2023 and the company’s confirmation of fixes suggests either complex remediation requirements or potential delays in addressing the vulnerabilities. The company’s refusal to disclose whether affected customers were notified contradicts growing global norms around breach transparency, particularly as automotive companies collect increasingly sensitive data about vehicle usage, location patterns, and driver behavior. This incident will likely attract scrutiny from Indian regulators under the country’s evolving data protection framework.
