Key fintech security threats: Types and examples

Over 70% of industry leaders anticipate a rise in financial crime risk in 2025, primarily driven by rapid technological advancements. This trend reflects a sad reality: in 2024, 64% of global financial organizations experienced an increase in cyberattacks.

But it’s not just the volume of threats growing—their nature is evolving, too. Below are the main fintech security concerns that businesses in the industry should keep on their radar.

Ransomware attacks

Ransomware is malware that blocks access to an organization’s systems until a payment (ransom) is made to restore it. According to the WEF Global Cybersecurity Outlook, 45% of surveyed organizations across industries ranked it among their top security risks, and businesses in the financial sector are no exception.

In 2024, over 65% of financial companies were targeted by such incidents. While not all attempts were successful—52% of efforts to compromise backups failed—they still caused substantial financial damage. Organizations in the financial services industry that fell victim reported an average cost of $2 million to recover their data.

Beyond the high cost of remediation, ransomware incidents often result in operational disruptions, reputational harm, and penalties for non-compliance with strict regulations governing the sector, further compounding the overall business impact.

Data breaches

Potential data breaches can arise from any form of unauthorized access to sensitive information, for example, names, bank account details, or Social Security numbers. Common causes include system vulnerabilities, human error, inadequate data security practices, or gaps in business operations.

According to the IBM report, financial firms incurred the second-highest data breach costs in 2024, averaging $6.08 million, which is significantly higher than the global average of $4.88 million. Furthermore, it takes financial companies up to 168 days to detect a breach and another 51 days to resolve it, therefore allowing bad actors to access sensitive data for over seven months.

However, what makes data breaches especially dangerous is that they often lay the groundwork for further crimes. Stolen data may be sold on the dark web, used to commit financial fraud, and leveraged for identity theft or blackmail.

Third-party vulnerabilities 

Fintech companies often depend on external vendors, such as third-party software providers, to support their business operations. While many of these vendors comply with general data protection regulations, their overall security posture is typically weaker than that of financial organizations. 

For example, when a fintech company uses cloud services, it entrusts a cloud provider with critical infrastructure. Even though major providers like AWS, Azure, and Google Cloud implement robust protection measures, the shared responsibility model still leaves room for potential security risks.

What’s worse, given the interconnected nature of fintech IT ecosystems, a single API security gap can trigger a major attack, affecting multiple systems and services.

According to fintech security experts in the Modern Bank Heists Report 2025, cloud infrastructure and APIs are among the most common entry points exploited in cyber attack attempts. Another survey reveals that 58% of large financial institutions in the UK experienced at least one cyberattack related to third-party relationships in 2024, with 23% falling victim to three or more incidents. 

Identity-related frauds

Identity-related fraud involves manipulating or fabricating personal information to gain unauthorized access to funds or data, bypassing security controls. According to research, 42% of all suspicious activity reported by financial organizations is linked to this type of security threat.

Traditionally, identity-related fraud has been limited to identity theft, where bad actors steal real personal information and use it for financial gain. But as technology evolves, these schemes become more advanced, involving:

• Synthetic identities. These are fake identities created by combining real and fabricated information to access financial services, like opening credit lines or taking out loans. A striking 72% of financial organizations report encountering synthetic identity fraud during client onboarding.
• Deepfakes. These are AI-generated audio, video, or images used to impersonate real people. For example, a fraudster might mimic an executive’s voice to authorize financial transactions. Deloitte estimates AI-powered fraud losses could reach $40 billion in the US by 2027, driven by voice cloning and deepfake video attacks. As GenAI advances, identity-related frauds are becoming easier to execute yet harder to detect.

Best practices for advanced security in fintech

As cyber attacks grow more advanced, fintech companies can no longer afford to treat the protection of their businesses and data as an afterthought. Staying ahead of evolving threats requires proactive, advanced security measures powered by the latest technologies. Below are key best practices that help prevent cyber risks, safeguard sensitive customer data, and ensure compliance with ever-tightening banking regulations.

Zero-trust architecture

Zero-trust architecture is a cybersecurity approach that assumes no user, whether internal or external, should be trusted by default, and every access request must be verified. Technically, it is implemented through:

• Role-based access control ensures that users only get the minimum level of access required to perform their tasks.
• Multi-factor authentication provides an additional verification layer, making it harder for cyber criminals to succeed when using stolen credentials.
• Network micro-segmentation limits how far an attacker can move by dividing networks into small, secure zones and isolating sensitive systems. 

Modern zero-trust models also rely on real-time analytics and machine learning for advanced threat detection and automated response actions.

Adopting a zero-trust approach lays a foundation for next-level fintech security, as it reduces the risk of third-party and insider threats, blocks attackers from gaining access to the entire IT setup, and minimizes the impact of potential breaches. On top of that, it enables fintech companies meet stringent compliance requirements such as SOX, PCI DSS, and GDPR.

Biometric and behavioral biometric authentication 

Biometric authentication confirms an individual’s identity based on unique physical characteristics, usually through fingerprint and facial recognition. This type of authentication is now increasingly familiar to users, as it’s part of their everyday smartphone experience. 

Many mobile banking apps, such as PayPal, N26, and Chase Mobile, leverage the devices’ built-in biometric authentication features, like Touch ID and Face ID, to enhance security and user convenience. Revolut, the leading global neobank, takes it a step further by adding the Wealth Protection identification feature, which verifies user identity using selfie IDs. This extra security layer helps prevent fraud, even if a phone is stolen.

Behavioral biometrics enhance authentication security by analyzing patterns in user behavior, including scrolling preferences, typing speed, and app navigation habits. Some US banks already use this advanced threat detection technology to mitigate the growing risk of account takeovers.

Secure practices for software development and integrations

Secure software development helps fintech companies minimize vulnerabilities and business logic flaws in custom systems, reducing the risk of potential breaches. At the same time, rigorous integration protocols limit threat exposure from third-party software. These practices are implemented through: 

• Secure software development lifecycle: integrating security into the development of financial technology solutions from the outset and conducting regular code reviews to identify flaws early on.
• Software composition analysis: analyzing open-source components and third-party libraries within the system to ensure security, license compliance, and the absence of vulnerabilities.
• Data encryption: using strong encryption for both data at rest (e.g., in databases) and data in transit (e.g., during API communication).
• Security-focused vendor management: performing thorough security assessments of all vendors and including compliance obligations in agreements.
• API security: using API gateways with rate limiting, logging, and threat detection to ensure only legitimate, rate-controlled, and monitored traffic reaches the company’s infrastructure.
• Security solutions: implementing advanced security tools like firewalls and intrusion detection systems to prevent cyber attacks.
• Cloud security monitoring: having security teams regularly audit cloud infrastructure for misconfigurations and vulnerabilities.
• Dynamic application security testing: simulating real-world outside attacks on a running app to uncover potential weaknesses before they are exploited by malicious actors.

In addition to technical measures, it’s essential to raise cybersecurity awareness across both development and business teams. This can be achieved through regular security training for employees. When working with an external tech team, it’s equally important to choose a reliable partner who specializes in fintech development and understands the industry’s strict security standards.

Regulatory compliance 

By adhering to standard security protocols and data privacy laws, fintech companies can greatly reduce the risk of breaches and protect customer rights. The main industry regulations include: 

• PCI DSS—a global standard for securing payment card data.
• GDPR—an EU regulation that governs the protection of personal data.
• PSD2—an EU directive that enforces strong customer authentication and other security measures in digital banking.
  SOX—a US law focused on financial reporting and internal control requirements.
• GLBA and FFIEC guidelines—US regulations aimed at safeguarding consumer financial information and ensuring cybersecurity compliance.

Many fintech security regulations are not just theoretical—they mandate specific technical safeguards, such as access management rules, data encryption, and audit logging, to protect sensitive information. That’s why working with a reliable partner who combines technical expertise with deep industry knowledge is essential for ensuring compliance.

In addition to preventive measures, fintech companies must have a clear incident response plan that outlines how they respond to and recover from security breaches.

Key trends in fintech security

As cyber attacks grow in technical complexity, fintech security measures are evolving just as rapidly. Below are the key trends organizations are adopting to better protect their data, operations, and customers.

The rise of AI in fintech security

Artificial intelligence (AI) is increasingly used to enhance security in fintech, particularly in the fight against financial fraud. According to the BioCatch survey, about 74% of institutions leverage this technology to detect financial crimes. One example is Mastercard, which uses it to analyze one trillion data points and the relationships between transactions to spot potential risks. With AI-powered capabilities, they’ve boosted fraud detection rates by 20%.

Liveliness detection

Liveness detection is a technology that verifies whether a person is real by analyzing factors such as eye movement, blink rate, and light reflections. An increasing number of fintech companies are integrating it into their Know Your Customer (KYC) systems to combat identity-related fraud. For instance, iCard, an innovative payment company, uses Regula Face SDK in its security system. This SDK, among other features, performs liveliness detection and face-matching.

Predictive analytics

By employing predictive analytics, fintech companies can shift from reactive to proactive security measures. For example, Citibank has integrated predictive models into its threat detection systems to identify potential fraud risks before they occur. These models focus on detecting abnormal behavior, such as unexpected account activity or transactions originating from unusual locations, helping anticipate and prevent financial crimes.
