Introduction
India’s financial sector is evolving at an unprecedented pace. With the rapid adoption of digital banking, UPI transactions, and fintech innovations, convenience has soared—but so have cyber threats. Cybercriminals are targeting Indian banks, financial institutions, and everyday users with increasingly sophisticated attacks, leading to billions in financial losses each year.
On February 7, 2025, Sanjay Malhotra, the Governor of the Reserve Bank of India (RBI), issued a strong warning to banks, NBFCs (Non-Banking Financial Companies), and fintech firms. He emphasized that cyber fraud is rising at an alarming rate and urged financial institutions to improve their cybersecurity infrastructure.
RBI also announced a new security initiative—the mandatory use of secure domain names (‘bank.in’ and ‘fin.in’)—to curb phishing attacks and protect customers from fraudulent websites. According to the RBI Cybersecurity Guidelines 2025, this measure aims to reduce digital fraud in India’s financial sector.
Let’s explore the growing cybersecurity threats in India’s financial sector, how RBI is responding, and what banks, businesses, and users can do to stay protected.
The Alarming Surge in Cyber Fraud Cases
India has seen a dramatic increase in digital fraud cases in recent years. The rise of UPI, mobile banking, and digital wallets has provided criminals with new attack vectors.
According to a report by CERT-In (India’s Computer Emergency Response Team), cybercrime cases targeting financial institutions have doubled in the last three years. The Indian banking system lost ₹1.25 trillion ($15 billion) in cyber fraud cases in 2024 alone.
Most Common Cyber Threats Targeting India’s Financial Sector
1. Phishing & Smishing Scams
- Fraudsters send fake emails (phishing) or SMS messages (smishing) pretending to be from banks.
- Victims are tricked into clicking on fraudulent links and entering sensitive data like bank login credentials and OTPs.
- Example: In January 2025, cybercriminals launched a mass phishing campaign impersonating SBI and ICICI Bank, tricking users into updating KYC details on fake websites.
2. Banking Trojans & Malware Attacks
- Malicious software is injected into devices to steal banking passwords and OTPs.
- Some malware even overlays fake banking login pages to siphon funds.
- Example: The Drinik malware, which resurfaced in 2024, targeted Indian bank users with fake tax refund alerts.
3. UPI Fraud & SIM Swapping
- Scammers trick users into approving fraudulent UPI transactions.
- SIM swapping allows attackers to bypass OTP authentication and gain full control over banking accounts.
- Example: Over 7,000 cases of SIM swap fraud were reported in India in 2024, affecting top banks like HDFC, Axis Bank, and Kotak Mahindra Bank.
4. Digital Lending & Investment Scams
- Fake loan apps offer instant loans but steal customer data and impose hidden high-interest fees.
- Fraudulent investment platforms promise high returns but disappear with investors’ money.
- Example: In 2024, the RBI banned over 150 fraudulent lending apps, many linked to foreign cybercriminal networks.
5. Ransomware Attacks on Banks
- Hackers lock critical banking systems and demand ransom payments to restore access.
- Financial institutions have been primary ransomware targets globally.
- Example: In 2023, Indian cooperative banks suffered a wave of ransomware attacks, paralyzing services for several days.
6. ATM & Card Skimming Fraud
- Attackers use skimming devices on ATMs and steal card details.
- Stolen data is sold on the dark web or used for fraudulent transactions.
- Example: In December 2024, a Mumbai-based ATM skimming gang stole data from 50,000+ bank cards.
RBI’s Response: Introduction of Secure Domain Names
To tackle the surge in cyber fraud, the RBI has introduced mandatory domain names for banks and NBFCs to prevent fake websites and phishing scams.
New RBI Guidelines
‘bank.in’ → Exclusive for Indian banks
‘fin.in’ → Reserved for non-banking financial institutions
Why This Matters?
Cybercriminals create fraudulent banking websites to steal customer credentials. The RBI’s initiative aims to:
- Reduce phishing attacks by eliminating fake banking domains.
- Enhance customer trust in official banking websites.
- Protect financial data from being misused by cybercriminals.
Implementation Timeline: Banks and NBFCs must migrate to ‘bank.in’ and ‘fin.in’ domains by mid-2025. Further details on RBI’s cybersecurity measures can be found in the RBI Guidelines.
What Financial Institutions & Users Must Do to Stay Safe
For Banks & Financial Institutions
Strengthen cybersecurity infrastructure :– Invest in AI-driven fraud detection systems to analyze transaction patterns and detect anomalies.
Regular penetration testing :– Perform vulnerability assessments and fix security loopholes before attackers exploit them. More insights on cybersecurity measures can be found at CERT-In.
Improve customer education :– Conduct awareness campaigns on phishing, malware, and UPI fraud prevention.
Adopt multi-factor authentication (MFA) :– Enhance security with biometrics and OTP-based verifications.
Establish a Cyber Response Team :– Deploy real-time threat intelligence systems to monitor and mitigate attacks.
For Individual Users
- Verify banking URLs before entering login details. Only trust websites ending in .bank.in or .fin.in.
- Never share OTPs, passwords, or banking details via phone or email.
- Use official banking apps rather than accessing banking portals via Google search.
- Enable transaction alerts to receive real-time SMS/email notifications.
- Report cyber frauds immediately at Cybercrime.gov.in.
- Avoid public Wi-Fi for banking transactions as they are vulnerable to man-in-the-middle attacks.
Conclusion: A Wake-up Call for India’s Financial Sector
India’s financial industry is at a crossroads—digital transformation has brought immense convenience but also greater risks. Cybercriminals are innovating new ways to exploit vulnerabilities, and financial institutions must stay ahead of the curve.
The RBI’s introduction of secure domain names (‘bank.in’ & ‘fin.in’) is a landmark step in fighting phishing and online fraud. However, banks, NBFCs, fintech firms, and customers must remain vigilant by adopting stronger cybersecurity practices.
With better regulations, proactive security measures, and greater awareness, India’s banking sector can stay resilient against evolving cyber threats.
