Financial Technology, or FinTech, is revolutionizing the way we handle money. FinTech is a catch-all term for lots of new technologies for doing financial things.
A few examples of FinTech include apps that allow you to bank on your phone, networks that allow you to pay other people without cash, platforms that allow you to lend money.
Every innovation comes with a risk and the largest risk for FinTech is cybersecurity. Customers and businesses can be very much at risk from cyberattacks, data theft, and hacking.
This article discusses the primary cybersecurity issues facing FinTech businesses nowadays and we provide easy and straightforward solutions to assist you in addressing these issues.
1. Data Breaches and Sensitive Information Exposure
Challenge
This information is highly valuable to cybercriminals, who can use it for fraud, identity theft, and other activities.
FinTech services and applications manage sensitive information, including names, bank account numbers, credit card numbers, identity cards, and biometric information.
Cybercriminals Hackers can steal a person’s identity, misuse it for ill purposes, or sell it on the dark web. Potential Cloud-based or online FinTech companies have more data exposed.
Solution
- Encryption – Store data and transfer data encrypted. In order to secure data that is stored or sent, employ good encryption techniques like AES‑256 to store data that is not in transit and TLS/SSL to move data.
- Tokenization – Convert sensitive information (such as card numbers) to various symbols. If a token is hacked, it’s worthless without the process that connects it to actual data.
- Access controls – Share the critical data only with individuals who need it. Utilize role-based access controls (RBAC), least-privilege access, and secure audit logs to monitor data access.
2. Account Takeover and Unauthorized Transactions
Challenge
Fraudsters who wish to steal user accounts prefer FinTech platforms. They can enter through other people’s passwords, making them provide their passwords by lying to them, or impersonating other people.
They can use your account for evil things, such as altering it, stealing your money, or obtaining your information.
Solution
- Multi-Factor Authentication (MFA) – It is a security feature that requires users to use more than one method to authenticate themselves. For instance, users can provide a password and a code that is updated every few minutes, or they can provide their fingerprint or face scan.
- Authentication of device and location – When individuals attempt to log in from unfamiliar computers or locations, the system verifies whether indeed it is them. Request additional evidence in such instances.
- Behavior analytics – Employ an engine that is rule-based or learns from data to observe how users behave (when they log in, how they handle money). Scan for anything unusual, like quick or large money transfers, or money from various sources within a short time.
- Educate users – Inform your users how to identify and evade phishing emails, how to generate and handle strong passwords, and how to report any suspicious or fake activities. Offer quick, short guides or tips in-app.
3. Secure Software Development and Vulnerabilities
Challenge
FinTech applications are advanced. They combine payments, identity checks, API services, third party data, and web or mobile user interfaces.
Bugs in coding or poor coding techniques can lead to security vulnerabilities like SQL injection, cross-site scripting (XSS), or exposed API endpoints.
Solution
- Secure development practices (DevSecOps) – Bring security into the whole development process. Inform developers on secure coding and scanning tools.
- Code reviews and static analysis – Scans code automatically for known vulnerabilities before it merges. Utilize ESLint, SonarQube, or proprietary scanners.
- Penetration testing – Use security testers to attempt to hack your service and find flaws.
- API security – Secure APIs with strong API authentication. Authorize access with OAuth 2.0 or JSON Web Tokens (JWT). Sanitize and validate all user input to block injection attacks.
4. API and Third-Party Risk
Challenge
FinTech companies rely heavily upon third-party services – payment gateways, identity verification, banking APIs, data feeds, analytics tools.
However, these may come with risk too. If a third party is hacked, it can affect your whole system.
Solution
- Vendor due diligence – Before integrating with a partner, review their security certificates, compliance (e.g. SOC 2, ISO 27001), and incident history.
- Isolate integration – Limit third-party access to only the data and features that are necessary. Use separate API credentials and roles.
- Continuous monitoring – Keep an eye on third-party API usage. Be on the lookout for unusual spikes or failed requests.
- Contract protections – Insert security and breach response provisions in your third-party contracts.
5. Employee Risks and Insider Threats
Challenge
At other times, the cybersecurity problems come from within. Disgruntled workers, careless practices, or plain human error can spill sensitive data.
Examples include sending passwords, using personal devices, or emailing sensitive information by accident.
Solution
- Staff training – Continuously train staff in best practices secure passwords, phishing, safe data handling.
- Access control and logging – Provide access based on role. Keep records of who accessed what when. Regularly scan the logs for anomalies.
- Device policies – Restrict use of personal devices for work. If home work is required, use secure, managed devices or provide device management features.
- Incident response planning – Consider insider incidents—data exfiltration, accidental deletion, or policy violations. Have separate escalation and response steps.
6. Legal Risks and Compliance with Regulations
Challenge
FinTech companies must adhere to various regulations such as KYC (Know Your Customer), AML (Anti-Money Laundering), GDPR (in the EU), or local financial regulations.
Non-compliance with regulation can result in huge fines, damage to reputation, or shutdown.
Solution
- Know your regulatory domain – Take the advice of legal experts to understand compliance needs in each place where you operate.
- Privacy by design – Day one design in privacy features diminish data collection, incorporate user agreement, make easy deletion of data.
- Data retention policies – Keep data only for as long as is legally required. Delete or anonymise securely when no longer needed.
- Reporting and audit trails – Maintain records that prove compliance such as who viewed customer data, when, and why. Automate regular reporting to the regulators where necessary.
7. DDoS Attacks and Availability Risks
Challenge
Distributed Denial of Service (DDoS) attacks flood your servers with traffic, which makes your service slow or unusable. For FinTech firms, service unavailability can have direct implications on revenue and trust.
Solution
- Cloud-based protection – Use services like Web Application Firewalls (WAF) or DDoS protection (e.g. Cloudflare, AWS Shield, Azure Front Door).
- Load balancing and auto-scaling – Allow automatic load balancing and scaling of traffic during spikes.
- Rate limiting – Limit requests per user or IP across a time window.
- Backups and redundancy – Have backup systems in geographically distant places, and failover and recovery tests on a periodic basis.
8. Mobile App Security Risks
Challenge
FinTech consumers mostly use mobile applications for banking or trading. Mobile apps are vulnerable to malware, reverse engineering, insecure storage, or insecure API calls.
Solution
- Secure mobile coding – Store tokens securely (e.g. Android Keystore, iOS Keychain). Utilize encrypted local storage. Always validate SSL certificates.
- Tamper detection and obfuscation – Hide app code to make reverse-engineering more difficult. Detects if the app is installed on a rooted or jailbroken device.
- Session protection – Log users off automatically after periods of inactivity. Avoid the use of long-lived tokens.
- Mobile threat detection – Make use of services that detect malicious activity or compromised-security devices.
9. AI and ML Model Security
Challenge
FinTech institutions increasingly use AI/ML for fraud detection, loan grading, behavior prediction of customers, or trading.
Yet models are not necessarily immune. Attackers can submit manipulated input to mislead the system (adversarial attacks), or they can extract sensitive data from models.
Solution
- Adversarial training – It teaches models to be resilient to malicious, manipulated inputs.
- Tamper-proof data pipelines – Maintain training data under control and from reliable sources. Monitor for data poisoning.
- Model access controls – Restrict who can call your models. Model inference request logging. Throttled model utilization.
- Private ML – Explore techniques like differential privacy or federated learning, which limit exposure of sensitive data to the model.
10. Incident Response and Crisis Management
Challenge
No system is perfect. At some point, a breach or attack will get through. How you react to the incident detection, containment, recovery, communication can be the difference between your reputation being made or broken.
Solution
- Incident response plan – There is a written document of who to notify, how to respond, which systems to isolate, and how to recover.
- Practice drills – Practice breach scenarios regularly to train your response team and equipment.
- Clear communication – In case a breach reaches customers, communicate clearly and quickly. Offer help and steps they can take.
- Post-crisis analysis – After the crisis, analyze what occurred and why. Update your systems, policies, and training based on lessons gained.
A Comprehensive Cybersecurity Framework
Putting all these pieces of the puzzle together, here is a simple framework that can be adopted by FinTech companies
- Governance and Risk Management – Stay up to date with regulations, have policies in place, and assess risk on a regular basis.
- People and Training – Empower all employees from developers to customer support staff with security habits.
- Secure Development and Infrastructure – Code with security in mind. Harden infrastructure through encryption, isolation, and monitoring.
- Data Protection – Encrypt, tokenize, and apply strict access controls to sensitive data.
- Threat Detection and Monitoring – Embed behavioral analytics, logging, and anomaly detection capabilities.
- Incident Response and Recovery – Pre plan incidents, conduct drills, and learn from real incidents and training on lessons learned. And training on lessons learned.
Real-World Example (Illustrative)
A medium FinTech company offering peer-to-peer lending witnessed persistent phishing attacks in which the attackers posed as employees in order to mislead customers.
They also witnessed an unpatched API that supported SQL injection.
