The Banking, Financial Services, and Insurance (BFSI) sector has recently faced escalating cyber threats, exploiting vulnerabilities in file handling and data transfers.

BharatPay Data Breach

In 2022, BharatPay, a fintech company that provides various digital financial services to customers and merchants based in India, experienced a significant data breach where personal and transaction data of around 37,000 users were exposed online due to a security lapse in data handling practices.

LockBit Ransomware Attack

Similarly, in May 2023, a state-owned bank in Southeast Asia fell victim to the LockBit ransomware group, which gained access to the bank's network through compromised credentials, resulting in substantial data exfiltration.

Cosmos Bank Cyber Heist

Another recent example is the Cosmos Bank cyber heist, where hackers siphoned off $13.5 million in a coordinated attack across 28 countries, exposing the vulnerabilities in the banks file and data handling protocols.

These incidents underscore the critical importance of secure file management within the BFSI sector. Unverified uploads, insecure file exchanges, and reliance on removable media introduce substantial risk, making it easier for cyber threats to bypass traditional defenses. Financial institutions now require solutions that can detect and neutralize threats proactively while streamlining secure file handling to protect customer data and maintain trust. 

This customer story examines how a leading Taiwanese bank addressed these challenges through OPSWAT’s MetaDefender Managed File Transfer (MFT) and MetaDefender Core. By integrating these advanced security solutions, the bank reinforced its defenses against file-based threats, safeguarding operations and sensitive client information. 

Increasing Risks in File Management 

Realizing that cyberthreats continue to evolve, the bank evaluated its current methods for handling file transfers and determined that it had several security gaps. In particular, the reliance on USB devices for internal file transfers exposed the bank to potential data leakage and malware risks. Without an effective means of tracking and verifying USB-based file transfers, the bank faced heightened risks of sensitive data exposure and external threats.

Additionally, the bank encountered issues with unverified file uploads, especially during national relief initiatives that required clients to submit large volumes of documents. With no mechanism in place to validate these uploads, the bank’s systems were at risk of malware infections and unauthorized access. Handling these files safely became an urgent need, especially as the bank recognized the reputational and operational impact of a potential data breach. 

Finally, frequent personnel transfers within the organization introduced additional data security challenges. Moving files between departments via manual methods was inefficient and posed compliance risks, as sensitive information could be exposed during the transfer. The bank required a solution to securely automate these file exchanges without disrupting day-to-day operations.
