Introduction
The development process of a secure Fintech application is complex, time-consuming, and most importantly, expensive. If you don’t have an experienced team with an awareness of the Fintech security requirements, this process is almost impossible.
Understandably, modern Fintech applications deal with lots of personal and business data every day. That’s why such solutions require security of the highest level, starting from the idea stage, and being present throughout the entire lifecycle of the application.
Cybersecurity statistics and trends
Cybersecurity is now considered a ‘must-have’ for internet users. It’s comparable to a home alarm or an automatic lock system. You wouldn’t leave your front door exposed to robbers, so why would you leave your computer accessible to hackers? Especially if you own a business, you don’t want any of your personal information to end up on the dark web.
As a result, you’ll need to invest in firewalls, antivirus software, and possibly even cyber insurance. Here is the most recent cyber security data to assist you in preparing your defense against hackers:
- According to IBM Cost of a Data Breach Report , the average cost of a data breach reached $4.44 million globally in 2025. This is the first decline in five years, driven by faster AI-assisted detection. But breaches in the financial services sector cost $5.56 million on average, the second-highest of any industry after healthcare.
- In the same report it was stated, that AI is now a factor on both sides of the fight: 1 in 6 breaches involved attackers using AI (most often for phishing or deepfake impersonation), while breaches involving unsanctioned ‘shadow AI’ tools cost organizations $670,000 more on average.
- Third-party and vendor involvement in breaches doubled year-over-year, from 15% to 30%, and ransomware was present in 44% of all breaches analyzed in Verizon 2025 Data Breach Investigations Report – up from 32% the year before.
- Cybercrime losses reported to the FBI topped $20.9 billion in 2025. This is a 26% jump year-over-year, and financial services climbed to the 3rd most-targeted critical infrastructure sector, up from 4th place the year before.
- 73% of leaders surveyed for The World Economic Forum’s Global Cybersecurity Outlook 2026 said they or someone in their network was personally affected by cyber-enabled fraud in 2025. Moreover, for the first time, CEOs now rank fraud as a bigger concern than ransomware.
Now, what are the top cybersecurity trends? According to Gartner’s Top Trends in Cybersecurity for 2026 report, they are:
- Agentic AI oversight: employees and developers are picking up autonomous AI agents and no-code/low-code tools faster than security teams can track them. That leaves new attack surfaces nobody manages or secures, and they need governance of their own.
- Regulatory volatility and board accountability: shifting geopolitical rules and mandates now carry direct liability for boards and executives for compliance failures.
- Post-quantum cryptography: today’s asymmetric encryption won’t survive mature quantum computing. Migration needs to start now, or ‘harvest now, decrypt later’ attacks will catch up with long-lived sensitive data.
- Identity and access management for AI agents: traditional IAM (Identity and Access Management) wasn’t built for machine and agent identities. It needs registration, automated credential lifecycles, and policy-driven authorization for non-human actors too.
- AI-enabled security operations centers: AI speeds up alert triage and investigation, but it also brings new costs (staffing, upskilling, budget) that security leaders have to plan for.
- Human-centric security awareness is failing to keep pace with GenAI: over half of employees already use personal GenAI tools at work, and a third admit to uploading sensitive data to unsanctioned ones.
What are Fintech-associated risks?

Security measures should be a critical component of development, particularly in the case of Fintech. You cannot afford to threaten your clients’ privacy or consumer trust. There are numerous security flaws that credit unions, financial organizations, and banking institutions face. Here are the most common ones.
No unified app ownership
When it comes to defending mobile banking services in the Fintech industry, app ownership is one of the most dangerous weaknesses you need to account for. There are often two app owners: one is a peripheral owner and the other acts on behalf of the bank. The app is also owned by the bank’s IT department. Aside from that, an external business is working on the mobile banking apps and the governance of their APIs.
Because the three owners described above share accountability, this style of ownership creates major security concerns. As a result, there is a great probability of something going wrong at any time.
An expanding, semi-public API attack surface
APIs are usually the top attack surface in Fintech, and the reasons are concrete and repeatable:
- missing object-level authorization, which lets one user pull another’s data just by swapping an ID in the request
- weak or overly permissive authentication
- no rate limiting
Open banking regulation makes this worse by design: every new institution a Fintech integrates with adds another API endpoint, and therefore another potential entry point.
Risky data storage
Every mobile app you use saves your data in some form. Because the data in the Fintech services industry is so sensitive, storage solutions must be exceedingly secure to avoid vulnerability. This is the first line of defense against financial data leaks, program code loss, and unsecured storage space. If your internal storage has a vulnerability, hackers can obtain direct access to your sensitive data and use it to their advantage.
Failure in communication
Mobile apps must communicate with external data sources such as NFC, Bluetooth devices, servers, various permission processes, and authentication tokens. You cannot avoid this contact; otherwise, the software will not work properly. However, there is always the risk of such transactions being intercepted. So companies need to employ extra protection measures for data in transit.
Account takeover and credential-based fraud
Roughly a third of login attempts at financial institutions and Fintech platforms are now estimated to be account takeover attempts rather than the real account holder logging in. The root of the problem mostly sits upstream of Fintech itself: reused or breached passwords from unrelated data leaks, credential-stuffing bots, and SIM-swapping and session-token theft. It lets attackers skip MFA (Multi-Factor Authentication) entirely instead of trying to break it. That’s why the identification and authentication controls covered later in this article carry so much weight.
Synthetic identity and AI-enabled onboarding fraud
A newer risk, and one growing fast, sits at account opening rather than account takeover. Generative AI makes fabricated identity documents and deepfake video easy to produce, good enough to beat remote verification. So fraudsters build ‘synthetic identities’: a mix of real and invented data that clears standard KYC checks. These identities then get nurtured like ordinary customers for months before being cashed out for fraud. Point Predictive research found synthetic identities accounted for 45% of US auto lending fraud by early 2025, and a BioCatch industry survey found 72% of institutions had run into synthetic identities during onboarding.
The core issue: identity verification was designed for physical documents and one-time checks, but not for AI-generated documents and ongoing risk.
What to take into consideration while developing a Fintech application
Secure infrastructure
During the Fintech application development process, it’s very important to use a reliable and secure IT infrastructure to avoid endangering your user’s sensitive data. If your app has to use a public cloud, think of choosing a trusted cloud service provider that meets the latest cloud computing security standards.
There are a lot of such standards, but it’s very important to mention the following:
- ISO-27001 / ISO-27002
ISO-27001 contains the Information Security Management System (ISMS) specification. ISO-27002 describes the controls that can be implemented in accordance with the ISO-27001 standard. Compliance with the ISO-27001 standard shows your customers that your organization is serious about information security and implements the best practices for protecting information. - ISO-27017
This is an extension to ISO-27001 that includes clauses related to information security in the context of the cloud. Compliance with ISO-27017 should be considered alongside ISO-27001. - ISO-27018
This standard refers to the protection of personally identifiable information (PII) in public clouds acting as PII handlers. This standard specifically targets public cloud providers such as AWS or Azure.
The AWS Enterprise Cloud has everything to counter massive DDOS attacks. It will also provide fast recovery in case of disruption.
For financial institutions that build their Fintech apps based on cloud infrastructure, it is highly important to ensure that the cloud service providers adhere to the same standards that they use internally.
Cybersecurity requirements for Fintech applications can be different depending on the company’s location:
- For the European Union – GDPR, PSD2 (soon to be replaced by PSD3, expected 2027–2028), eIDAS
- For the United Kingdom – GPG13, FCA
- For Japan – APPI
- For South Korea – PIPA
- Worldwide – PCI DSS, ISO/IEC 27000
Application logic security
Building secure application logic means the integration of security at every stage of the application’s performance. Every aspect of your future application needs to be protected from potential threats.
Consider the following security actions:
- Requiring users to set complex passwords;
- Complicated authentication, e.g., two-factor;
- Keeping a datalog of all the user’s actions, their geolocation, IP addresses, and device info;
- Keeping users’ information encrypted to avoid attackers getting personal data as it is;
- Monitoring of transactions and blocking suspicious ones;
- Doing regular backups;
- Practicing security rehearsals.

Secure code
Fintech application code should be easily portable between devices and include algorithms to easily detect any problems in the case of a breach or an attack. At the very least, the process of updating the code has to be simple.
The best practices for writing secure application code include input review and the validation of any data that is sent to external networks. Access should be granted only to the basic functions of the application, rules have to be defined clearly, and all the necessary steps have to be taken to ensure the protection of sensitive data. And don’t forget about SQL injection protection – your Fintech app can still be hacked that way.
Web-server security
Since the web server is the most common target for external attacks, it is now common practice to secure the data with an HTTPS SSL certificate. Most popular browsers will warn users when a website has no such certificate, so you obviously cannot skip this step and remain a trustworthy service.
Another common practice is using a VPN. It complicates the setup stage, but this step is worth your efforts because access will only be given to the hardware with a valid public key.
API security
Most users run Fintech applications on mobile devices. Such apps use application programming interfaces (APIs) to interact with their backend. That’s why APIs are also regular targets of attacks, and you have to keep them secure to protect the rest of the application.
Identification, authentication, authorization
The identification, authentication, and authorization system should serve as a reliable barrier against any invasion or suspicious activity. Your authentication methods should not be limited to just passwords. Combine them with SMS verification or one of the latest biometric authentication methods such as a fingerprint or retinal scan.
During authorization, the application identifies the user as a person who is either allowed or not allowed to perform certain tasks. Ideally, user rights should be limited to a certain set of actions and commands.
There are several different authentication technologies, including:
- One-time password system
The app automatically generates an additional password with a limited expiration date every time the user wants to log in to an account or complete a transaction. - Mandatory password change
Fintech organizations can significantly reduce security risks by forcing customers and employees to change passwords regularly. Many online banking applications require you to reset user account passwords every three or six months. - Monitoring
With the help of a tracking system, you can analyze suspicious activity (for example, failed logins) to identify cases of unauthorized access. In addition, this solution can prevent data leakage by locking the account after several suspicious transactions. - Short log-in sessions
The shortened session time is useful for protecting financial data. The reason is that even if a hacker gains access to the account, he will have limited time to collect the important data. - Adaptive authentication
Multi-factor authentication is not a panacea. In fact, it can even increase the risks of data leakage (for example, if a hacker manages to clone your smartphone). But with adaptive authentication, your system will analyze user behavior to detect suspicious activity. As a result, your platform will receive additional protection for financial data and personal information.
Data encryption techniques
You have to encrypt your user’s personal information (name, address, social security number) and their financial data such as credit card numbers and payment history, as well as any other information that may be obtained upon receipt of a particular financial service.

Encryption is essential to protect data during transmission when it is highly vulnerable and can be easily snapped up. Secure data transmission involves the use of various encryption algorithms; for example, the US federal government uses AES, which is currently considered the most secure.
You can protect critical data with complex encryption algorithms, such as:
- RSA
A highly secure asymmetric algorithm with a private encryption key and a public encryption key. - Twofish
A freeware algorithm that encrypts data into 128-bit blocks. - 3DES
The preferred encryption method to secure credit card PINs. Triple DES divides data into 64-bit blocks and ciphers each one three times.
A forward-looking note: RSA and similar asymmetric algorithms are exactly the kind of encryption Gartner flags as at risk from future quantum computing. Security teams don’t need to migrate overnight, but should start inventorying where these algorithms protect long-lived sensitive data and build a path toward post-quantum, ‘crypto-agile’ alternatives, since data encrypted today could still be harvested and decrypted later once quantum computing matures.
Payment blocking feature
One way to prevent fraud is to point out suspicious activity. Use something that will be significantly different from the usual user activity, for example, unusually large amounts of money transferred from unusual locations.
To protect the user from possible fraud, implement a payment blocking function in your application. This feature will provide immediate blocking of payments after something, unlike the user’s normal activity, is detected.
Security testing
Creating secure Fintech solutions requires meticulous testing at each of the development stages.
It is common practice to conduct ‘penetration testing’ – launching your own simulated attacks to discover vulnerabilities in your application. Needless to say, continuous and thorough testing should be an integral part of the development process. It’s possible to hire security testers to create high-quality, attack-resistant code.
Also, one of the practices is to simulate potential emergencies and create ways of handling them for the personnel.
Establish clear and consistent access rights to prevent data leakage at every stage of the development process, ask your employees to sign an NDA, and use corporate equipment on your premises.
Today, many financial companies are ISO-27001-certified. The certification and confirmation process is complex, but having that certificate will mean that your company is using truly top-notch security practices.
Code obfuscation
Cybercriminals can clone a Fintech app to steal personal user data while remaining undetected. To prevent app copying, Fintech companies should consider code obfuscation. Encrypting the code, removing revealing metadata, labeling classes and variables with meaningless labels, or adding useless or meaningless code to an application binary are all examples of code obfuscation.
AI to track user transactions
To prevent various cyber assaults, the Fintech app can keep track of all significant user behaviors such as user IDs, device data, IP addresses, geolocation, and transactional activity. Artificial Intelligence can be used to maintain a constant eye on users’ behavior to detect common trends and odd behavior. One example would be to block suspicious transactions from an unknown or odd IP address.
Tokenization
Tokenization is the process of replacing vulnerable data with a newly produced random string of symbols known as tokens. Only authorized users will have access to a one-of-a-kind database known as the ‘token vault,’ which retains all relationships between the original data and the produced token. Tokenization makes PCI compliance easier by safeguarding data within organizations and online transactions.
Regular data backup
Data loss isn’t always the consequence of an external danger; it can also be the result of human error or technology failure. Making a backup of important data keeps it from being completely lost. To save as much altered data as possible, make sure that key files are periodically backed up, including edited and changed data.
Vulnerabilities monitoring in the installed packages
Fintech apps frequently make use of third-party software vendors. But third-party apps may contain vulnerabilities and weaknesses that fraudsters might exploit, making the whole system rife with security issues. Hackers can carry out a supply chain attack, in which they compromise a third party to gain access to data.
It’s better to screen third-party suppliers before using their services and monitor them frequently during installation. It will assist you in identifying vulnerabilities in your project, revealing which areas are affected and what needs to be fixed.
Fintech security in the age of AI
Generative AI has changed fintech security into a genuine arms race, where the same underlying technology accelerates both attack and defense. Apparently, the data suggests attackers are moving faster.
The offense side
The clearest signal is Deloitte’s Center for Financial Services projection that generative AI could enable fraud losses to reach US$40 billion in the United States by 2027, up from US$12.3 billion in 2023 – a 32% compound annual growth rate.
On identity fraud specifically, Deloitte found more than 40% of financial professionals have directly encountered deepfakes in fraud attempts, and 90% say fraudsters are actively using generative AI. Sector-wise, cryptocurrency and fintech are disproportionately targeted: Sumsub found deepfakes accounted for 11% of global fraudulent activity by 2026, with earlier data showing 88% of deepfake fraud cases concentrated in crypto and 8% in fintech.
The defense side: AI cuts costs, but only when governed
Globally, average breach costs fell 9% to $4.44 million, the first decline in five years, driven by faster AI-powered detection – breaches were contained in a mean of 241 days, the lowest in nine years. Organizations using AI extensively in security operations saved an average $1.9 million per breach and cut the breach lifecycle by 80 days. For financial services specifically, average breach cost was $5.56 million – above the global average, driven by regulatory fines, fraud liability, and sophisticated attacks.
But the same report identifies AI as a new liability. 97% of organizations that had an AI-related security incident lacked proper AI access controls, and 63% had no AI governance policy at all. ‘Shadow AI’ – unsanctioned tools employees use without oversight – added $670,000 to the average breach cost, and AI was involved in 16% of all breaches in 2025, mostly powering phishing and deepfakes.
The takeaway is that AI adoption in fintech has outpaced AI governance almost everywhere – including at the institutions that understand the risk best.
AI-related attack vectors in Fintech and technical countermeasures
The statistics above describe the scale of the problem, but they don’t tell you where to put resources. This table breaks the threat down into the specific cases fintechs are actually seeing alongside the technical controls worth putting in place for each one to prevent it.
| Attack scenario | How it works | Technical countermeasures |
| Voice cloning / vishing (fake CFO, fake relative, fake ‘bank agent’) | 20-30 seconds of audio is enough to clone a voice convincingly, per FS-ISAC – used for wire-transfer authorization calls or contact-center social engineering. | Out-of-band transaction confirmation (a second channel that a live call can’t spoof). Mandatory callback to a pre-registered number, not one given during the call. Voice liveness/anti-spoofing at contact centers (Pindrop-type detectors, though these degrade against newer TTS and must be re-benchmarked regularly). Hard dual-approval thresholds for wire transfers that no single call can override. |
| Video deepfakes in live calls (fake executives on video conferences authorizing transfers) | Real-time face-swap/avatar tools now run convincingly on consumer hardware. | Cryptographic transaction signing that requires action outside the video call (hardware token, authenticator app). Policy that no payment instruction is valid from a verbal/video request alone, regardless of who appears to be speaking. Internal comms tooling with verified/signed sender identity for high-value approvals. |
| Presentation attacks on biometric onboarding (photos, screens, masks held up to a camera) | Attacker presents a static or replayed image/video to a selfie or liveness check instead of their real face. | Liveness detection certified to ISO/IEC 30107-3, tested by an accredited lab (e.g., NIST/NVLAP-accredited iBeta). Require vendors to disclose APCER/BPCER scores at your chosen operating threshold – a vendor unwilling to share these numbers isn’t ready for regulated use. |
| Injection attacks (bypassing the camera entirely, feeding synthetic video / image data straight into the verification pipeline via virtual cameras or manipulated data streams) | Rather than fooling a camera, the attacker injects fabricated media directly into the software pipeline. | Device and sensor integrity checks (detect virtual camera drivers, emulators, jailbroken/rooted devices). Cryptographic attestation of the capture pipeline (proof the image comes from a real camera sensor, not an injected stream). Active liveness challenges that a pre-recorded or injected stream can’t respond to in real time. |
| Synthetic identities & AI-generated documents (fabricated faces/IDs that pass automated checks) | Generative models produce faces of people who don’t exist, or forge IDs, to open accounts that later serve as fraud or money-laundering vehicles. | Document forensics at the pixel/frequency level (detecting generation artifacts, not just visual inspection). Cross-checking against authoritative data sources (credit bureau, government ID databases, device/behavioral history) rather than relying on the document alone. Ongoing (not just onboarding-time) identity re-verification tied to anomalous account behavior. |
| AI-personalized phishing / BEC at scale | LLMs let attackers generate fluent, context-aware phishing emails personalized per target, at near-zero marginal cost. | Phishing-resistant authentication (FIDO2/passkeys instead of SMS/OTP – explicitly recommended in IBM’s Cost of a Data Breach Report 2025). Email provenance verification (DMARC/DKIM enforcement). Behavioral anomaly detection on payment workflows rather than relying on message content alone. |
| Shadow AI / ungoverned internal AI use | Employees feed sensitive data into unsanctioned AI tools. | AI access controls and an approved-tools inventory. DLP that blocks uploads of sensitive data to unauthorized AI endpoints. Formal AI governance policy with an approval process. |
| Model manipulation / attacks on the bank’s own fraud-detection AI | Adversarial inputs or data poisoning aimed at the institution’s own ML models to slip fraudulent transactions past detection. | Model monitoring for drift and adversarial input patterns. Audit trails covering training data provenance and access, now a formal requirement for high-risk systems under the EU AI Act’s Annex III. Regular red-teaming of fraud models, not just of the perimeter. |
What to expect if you ignore Fintech security?
Whether due to a blackout or ransomware, your organization is still responsible for preserving your customers’ data if it is lost or corrupted. You must consider the risk of every piece of information being handled during financial transactions.
Thibald Carty, CCO at ConnectPay says:
‘Now it’s possible to prevent fraud at the same — or even higher — efficiency with fewer people simply by utilising the appropriate tools and automation.’
Let’s have a look at some of the potential hazards and see what you should be especially wary of.
Identity theft
This problem arises when someone steals personal or financial information and gains access to your, your colleague’s, or your client’s private data, such as bank account passwords. Given the fact that anyone can be a victim of identity theft, it’s difficult to overlook the need of distributing access and specific functions within a corporate network among employees. Identity theft is also likely to trigger a cascade of further problems, such as phishing or spoofing, which can result in massive data and financial losses.
Abuse of a client’s trust
Good news is not likely to spread as quickly as bad news. If your clients are pleased with your Fintech app, they will undoubtedly continue to use it. Furthermore, they are inclined to tell their friends about it. But consider what happens if a customer’s data is compromised: not only will you lose the trust of your current client, but also of other potential consumers.
While improving financial security takes time and money, regaining trust requires significantly more effort.
Data loss
If a fraudster can read the data, it can be stolen, lost, or exploited. And if the stolen information is in plaintext or poorly encrypted, a hacker does not need to exert much effort to read and utilize it. Overall, it results in a breach of customer trust, reputational concerns, and profit losses.
These are the three key security issues. The bad news is that every system can be hacked, but the good news is that the magnitude of losses – such as the time and money required to recover – is determined by the strength of your financial security.
Fintech app security technologies to use

Secure Access Service Edge (SASE)
SASE (Secure Access Service Edge) is a network solution that combines VPN and SD-WAN expertise with cloud-native security measures such as secure internet gateways, cloud security brokers, firewalls, and zero-trust network access. Furthermore, the SASE architecture aids in network traffic analysis and detects dangerous digital data in fraudulent transactions, ransomware, and other similar situations.
Here is what Safi Raza, Director of Cyber Security at Fusion Risk Management is saying about this technology:
“SASE has been proven effective in securing the remote workforce during the pandemic. It is a cloud-based architecture that delivers network and security services to protect users, applications, and data.”
Artificial Intelligence (AI)
Fintech organizations are increasingly utilizing machine learning to properly comprehend financial data and security systems. AI algorithms can help detect malicious data streams, intrusions, and other dangers by tracking network traffic databases. AI also aids in the deep analysis of customer data to determine future clients’ strengths, shortcomings, and so on. This helps businesses prevent hazardous customers as well as future criminal transactions.
Digital currency
Cryptocurrency, or digital currency, is currently at its height. It is an essential component of blockchain-based decentralized finance frameworks. The ease, comfort, and speed with which digital transactions may be done astound the industry, but the integration of digital currency security is the most advantageous part for the Fintech business.
Regulatory technology
RegTech, or Regulatory technology, is a type of modern technologies that assist businesses in managing regulatory compliance. This tech, among other things, provides artificial intelligence, machine learning, and blockchain technology to help organizations comprehend regulatory requirements and monitor their content to maintain Fintech security compliance.
What to expect in the future?
Regulatory sandboxes
Many countries have created regulatory sandboxes, which are test environments where Fintech companies can conduct experiments under regulatory supervision. Some countries’ regulators (particularly the FCA in the UK) allow Fintech companies to conduct these experiments with real customers.
The United Kingdom’s Financial Conduct Authority (FCA) was the first agency to introduce a regulatory sandbox in 2016. Since then, over 70 jurisdictions around the globe have copied the FCA’s model. In the United States, several state legislatures have attempted to emulate the U.K.’s success by creating their own state-level sandboxes, but these efforts have had mixed results.
One of the challenges facing state-level sandboxes is that they are more limited in the kinds of benefits they can offer participants than national supervisors like the FCA. For example, Arizona’s sandbox companies can test their products for up to two years and serve as many as 10,000 customers before needing to apply for a formal license. However, they cannot offer financial incentives to customers or participate in government procurement programs.
Finance-as-a-service regulations
The catalog of APIs is growing and new regulations are emerging with every new advancement in Fintech. So the Finance-as-a-Service movement has seen significant growth in recent years, and this trend is expected to continue. Like other X-aaS products, Finance-as-a-Service is provided by unregulated organizations that offer regulated financial products.
The key changes that are expected for the FaaS market:
- The growth of embedded finance. Embedded finance is the integration of financial services into non-financial products and services. This trend is expected to grow, as businesses look for new ways to reach their customers and offer them financial services that are convenient and easy to use.
- The rise of open banking. Open banking is the sharing of financial data between banks and third-party providers. This trend allows businesses to offer their customers a wider range of financial services and products, so it’s expected to continue to grow.
- The increasing use of artificial intelligence. Credit scoring, fraud detection, and compliance checks run on AI as standard practice across most FaaS platforms. Costs drop, but model governance and bias raise new problems.
- The growing importance of security and compliance in the FaaS market. Regulators keep tightening rules on data protection, AML, and API security. Providers that can’t prove a strong compliance posture lose deals to ones that can.
Regulations of open banking
Open banking is in high demand, and industry leaders note that the data-sharing framework will become integral to the countries that are introducing it. Open banking has already established itself in Europe and is making significant headway in countries such as Australia and Canada. However, the United States is in no hurry to enact such regulations.
The Consumer Financial Protection Bureau (CFPB) finalized its Section 1033 open banking rule in October 2024, with compliance due to begin phasing in from April 2026. That timeline stalled: a federal court enjoined the CFPB from enforcing the rule while the Bureau reconsiders it, and the CFPB itself has told the court it now views the rule as unlawful and intends to rewrite it, including reopening whether banks can charge fees for data access. As of mid-2026, US open banking regulation is best described as paused and being rewritten rather than settled, and some states (e.g. New York) are moving to legislate their own data-access rights in the meantime.
Looking at this progress, governments and regulators will continue to enact laws and frameworks for open banking. In turn, banking data will continue to gain more layers of protection with the help of financial innovators worldwide.
Regulations of online payments and SCA
PSD2’s Secure Customer Authentication (SCA) requirement, in force since 2018–2021 depending on member state, is being superseded: the EU has agreed the text of a Third Payment Services Directive (PSD3) and a directly applicable Payment Services Regulation (PSR), which together replace PSD2 and the E-Money Directive with a single framework. Formal publication is expected around mid-to-late 2026, with the new rules applying roughly 21 months later (so realistically late 2027/2028 for full effect).
PSD3/PSR tighten fraud liability (including mandatory IBAN/name-match checks and clearer reimbursement rules for authorized-push-payment fraud), impose stricter, more enforceable open banking API performance standards, and expand SCA options to include combinations of biometric factors. Fintechs and banks operating in the EU should treat this as a multi-year compliance program, not a single go-live date, and should note its explicit alignment with the Digital Operational Resilience Act (DORA) discussed above.
As a result, merchants and other online retailers are seeking alternative payment methods, such as Secure Corporate Payment (SCP), Transaction Risk Analysis (TRA), Low Value Payment (LVP), Merchant Initiated Transaction (MIT), Recurring Payment (RP), SCA Delegation (SD), and Trusted Merchant (TM), to process transactions securely without compromising the user experience.
Tips for users on how to use Fintech apps securely and safely

In addition to assisting users in achieving more data privacy and protection online, we must also take action to protect ourselves.
Here are some security precautions for using Fintech apps:
- Make use of strong passwords. Use a strong password when creating your account. This entails combining letters, numbers, and symbols. It is also advisable to update your password frequently.
- Turn on two-factor authentication. Two-factor authentication can aid in the protection of your account against unauthorized access. Users will be required to submit two pieces of information to log in. The first is typically a password, while the second can be a PIN, biometric data, or a code sent to the user’s phone.
- Avoid using public Wi-Fi networks. Public Wi-Fi networks are insecure and readily compromised. If you need to use the internet while you’re out and about, consider using your data plan instead.
- Be cautious when clicking links. When clicking links in emails or on websites, use caution. Cybercriminals frequently utilize bogus links to obtain personal information from consumers. Only click on links that you are confident in.
- Update your software on time. Install the most recent security updates from the manufacturer to keep your software secure. This will aid in the protection of your device against malware and other online threats.
- Be skeptical of ‘urgent’ voice or video contact from your bank. AI-generated voice cloning and deepfake video are now good enough to impersonate a bank employee or even a family member – verify unexpected, urgent financial requests through a separate, known channel before acting.
Examples of cyberattacks on the Fintech industry
Despite the big differences in scope and environment, many of the attacks against Fintech organizations could have been avoided with one simple change: improved security architecture.
Most cyberattacks succeed as a result of the victim’s lack of caution, and those problems require a multi-layered approach. Here are some examples of the biggest cyberattacks in the Fintech industry.
LoanDepot
The BlackCat/ALPHV ransomware group breached the mortgage lender’s systems between January 3–5, 2024, exposing names, addresses, financial account numbers, phone numbers, and dates of birth of 16.6 million customers. The company took its loan servicing portal offline, leaving customers unable to make payments, and the incident ultimately cost LoanDepot nearly $27 million.
Evolve Bank & Trust
LockBit breached the banking-as-a-service provider after an employee clicked a malicious link, accessing databases and file shares containing Social Security numbers, account numbers, and contact information for 7.6 million people. Because Evolve provides infrastructure for fintech companies, the breach cascaded to their customers too, including Affirm, Wise, and Bilt Rewards all independently confirmed impact.
Coinbase
Attackers bribed individuals working in Coinbase’s overseas customer-support operations to improperly access customer account information, then attempted to extort a $20 million payment. Coinbase refused to pay and instead set up a $20 million reward for information leading to the attackers’ arrest.
Marquis Software
Ransomware group Akira exploited a known vulnerability (CVE-2024-40766) in a SonicWall firewall to breach Marquis, a data-analytics vendor serving hundreds of US banks and credit unions, exposing sensitive data – including bank account and card numbers – for over 670,000 people across 74+ institutions.
Arup
A finance employee at the engineering firm’s Hong Kong office authorized $25.6 million in transfers after joining a video call where every other ‘participant,’ including the CFO, was an AI-generated deepfake built from public footage of real executives.
Conclusion
As you can see, ensuring Fintech app security is a complex process requiring very specific knowledge and skills to deal with highly sensitive data.
