Strengthening Cyber Security in Banking: Lessons from a Singaporean Couple’s Identity Theft While Abroad in Japan

By: Abhishek Kumar Singh, Head of Security Engineering, Singapore, Check Point Software Technologies

In recent years, the escalating incidents of identity theft and cyber fraud have raised significant concerns about banking security in Singapore. The rise of technology has not only facilitated convenience in financial transactions but has also opened doors for malicious actors to exploit vulnerabilities within banking systems. The recent incident involving a Singaporean couple in Japan, whose banking accounts were blocked and credit cards cancelled by identity thieves, after they rang up the banks and pretended to be the couple, serves as a stark reminder of the potential shortcomings within the banking systems of today.

According to Check Point Intelligence Report, the Finance/Banking industry is the third most attacked sector in Singapore, averaging 1,790 weekly attacks per organisation. The industry is also third in place for the highest volume of phishing attempts, after technology and social network sectors. With cybercriminals becoming increasingly sophisticated, the need for robust authentication mechanisms has never been more urgent. Financial institutions can rethink their reliance on static personal information, such as identification numbers and card details, which are easily exploited through information breaches and social engineering techniques.

The Role of Multi-Factor Authentication (MFA)

Implementing multi-factor authentication (MFA) is a critical step towards enhancing banking security. MFA combines three key elements:

1. Something the user knows: A password or PIN.
2. Something the user has: A mobile device or token.
3. Something the user is: Biometrics such as fingerprints or facial recognition.

By integrating these layers, banks can significantly reduce the risk of unauthorised access. For instance, biometric authentication combined with one-time passwords (OTPs) sent to a registered device ensures that even if one security layer is compromised, others remain intact. This layered approach creates an additional safety net against identity theft. This approach has already been implemented in most banking systems and could potentially be extended to the scenario involving couples visiting Japan for validation before blocking the customer accounts.

Advanced technologies can further fortify these measures. AI-powered voice recognition systems, for example, can be deployed during call verification to distinguish between genuine customers and fraudsters attempting social engineering tactics. Such innovations not only enhance security but also improve user experience by streamlining authentication processes.

Operational Enhancements for Banks

Beyond MFA, banks can also consider adopting proactive strategies to detect and mitigate threats in real time. Anomaly detection models, powered by artificial intelligence, can play a pivotal role in identifying suspicious activities. For example, repeated call attempts with failed verifications can indicate potential fraud. Similarly, sudden high-risk requests, such as account block attempts, can be flagged for further scrutiny.

Additionally, secure APIs that facilitate tokenised data exchange can protect sensitive information during verification processes. This ensures that customer data remains secure while maintaining the seamless functionality of digital banking services. Such measures are vital in an increasingly cashless society, where consumer trust hinges on the security of financial transactions.

Empowering Consumers Through Cyber Hygiene

While banks bear the responsibility of implementing robust security measures, consumers also play a crucial role in safeguarding their accounts. Practising proactive cyber hygiene can significantly reduce the risk of falling victim to cyberattacks. Some actions that will make a difference include:

• Be Alert to Unusual Notifications: Pay attention to alerts for unauthorised transactions, login attempts, or account changes.
• Monitor Account Access: Investigate access denial or unexpected password failures, as these may indicate a compromised account.
• Scrutinise Transactions: Look out for small, irregular charges, which are often used to test account validity by fraudsters.
• Avoid Phishing Traps: Verify the legitimacy of emails or calls before sharing sensitive information or clicking on links.

Best Practices for Consumers

Adopting strong cyber security habits is essential for consumers in safeguarding their financial well-being. By combining awareness with practical measures, individuals can significantly reduce the likelihood of becoming victims of fraud or cyberattacks. It is good practice to:

• Enable Multi-Factor Authentication (MFA): Combine passwords with biometrics or OTPs for added security.
• Use Strong Passwords: Employ unique, random, and lengthy passwords, utilising password managers for secure storage.
• Regularly Review Transactions: Keep a close watch on banking and credit activity to identify discrepancies early.
• Update Device Security: Ensure operating systems and endpoint protection software are up to date.

Building a Secure Banking Future

A secure banking future will depend on a synergy between cutting-edge security measures and informed, proactive consumers. It is important for banks to embrace and prioritise investments in AI-powered technology to keep up with fast evolving digital landscape, and gain confidence in providing seamless yet secure experiences. Meanwhile, it is equally critical that consumers can learn to protect themselves, starting with practicing cyber hygiene habits that can reduce their digital vulnerabilities, such as updating software regularly and recognising phishing attempts.

In an era where cyber threats are ever-evolving, this dual approach fosters a resilient ecosystem where risks are mitigated before they escalate. Beyond mere prevention, it also paves the way for trust—the cornerstone of any financial relationship. As the world becomes increasingly interconnected, a shared commitment to cyber security will not only protect individual assets but also safeguard the broader financial infrastructure. Collaboration, education, and continuous adaptation are the pillars of a future where banking can thrive securely amidst an ever-evolving threat landscape.
