Literature Review

Cybersecurity and Data privacy in the fintech industry have emerged as critical issues that demand attention. The rapid growth of fintech has raised concerns about the security and protection of sensitive financial data. The increasingly heavy reliance on digital platforms and mobile applications for financial transactions has created vulnerabilities that threat actors can exploit. The World Bank and CCAF report highlights that cybersecurity risks are the biggest concern for financial regulators in the fintech industry. Furthermore, the implementation of financial insurance and the understanding of cyber risks pose challenges for fintech companies.

“FinTech”, a contraction of “Financial technology”, refers to technology enabled financial solutions. It is often seen today as the new marriage of financial services and information technology (Arner, D. at all, 2016). In (Gai, K., at all, 2020), the authors investigate the definition of Fintech and measure the extent of the impact of Fintech variables on the Cybersecurity as the dependent variable. (Cukier, K., at all, 2018) a major theme in this book is that “big data” will become the dominant scientific paradigm, and change society—and it may yet. Guidelines set out the EBA’s view of appropriate supervisory practices within the European System of Financial Supervision or of how Union law should be applied in a particular area. Competent authorities as defined in Article 4(2) of Regulation (EU) No 1093/2010 to whom Guidelines apply should comply by incorporating them into their practices as appropriate (e.g. by amending their legal framework or their supervisory processes), including where Guidelines are directed primarily at institutions (European Banking Authority, 2018). Special consideration is given to how blockchain-based identity and access management systems can address some of the key challenges associated with IoT security (Kshetri, N., 2017). Consumers, increasingly aware of their privacy rights, may seek alternative products and services without appropriate protections (International Association of Privacy Professionals, 2019). The Council is charged with identifying risks to the financial stability of the United States; promoting market discipline; and responding to emerging risks to the stability of the United States' financial system (Financial Stability Oversight Council, 2020). For example, in the paper (Smith, A. N., & Smith, B. L., 2018) they investigate the definition of Fintech and measure the extent of the impact of Fintech variables on Cybersecurity as the dependent variable. Beyond individual organizations, cyber risk is a systemic challenge and cyber resilience a public good. Every organization is a steward of information they manage on behalf of others. And every organization contributes to the resilience of their immediate customers, partners, and suppliers and the overall shared digital environment (World Economic Forum, 2019). This study (Apostu, S. A., at all, 2022) may also help policymakers and regulators to structure and improve their policies toward investing in financial markets, as cryptocurrencies require multiple risk-mitigation approaches for investors and financial markets. As researchers and practitioners alike seek to identify new ways to solve business challenges, inspire financial innovation, and create and seize new opportunities, insurers around the world are increasingly teaming up with insurtechs, and other tech startups (Manta O, at all, 2023). There has been an increased recognition that more attention needs to be paid to AI, the internet of things, environmental, social, and governance (ESG), sustainability, adoption, and intelligent automation (Tong L, at all, 2022). Also in the specialized literature, we identified the work (Brooks C. J., et all, 2018), which offers clear and comprehensive details on cyber security, with a direct orientation towards current challenges, namely:

• How to secure the infrastructure.
• How to secure and control devices.
• How to secure of local and global networks, as well as securing and protecting the perimeter.

This scientific work deals with these challenges and demonstrates to us through the analyzed scenarios, those vulnerabilities (Brooks C. J., et all, 2018), that each system user may face in their daily professional life. In the digital age, individual autonomy should prevail, and this aspect must be carefully protected through clear tools and mechanisms. (Becker, M., 2019) starts from the privacy debates, and through the aspects mentioned by the author helps us how to protect personal autonomy in the digital age, an essential aspect especially in the context of fintech financial instruments. As also presented by (Yuchong Li et all, 2021)), cyber security “tracks real-time information about the latest IT data”. It is obvious that at the global level, especially in the context of AI, researchers at the international level propose tools, various methods, models to prevent and limit cyber-attacks, but above all to limit the damage generated by these attacks.

The rapidly evolving fintech industry has witnessed a surge in cybersecurity and data privacy concerns, prompting extensive research and diverse perspectives on addressing these challenges. The world bank and CCAF identify the need for increased collaboration between insurers and insurtechs to drive financial innovation and address the evolving landscape of risks, such as AI, IoT technologies, ESG factors, sustainability, and intelligent automation. (Contributors, 2023). Existing research explores the multifaceted nature of cybersecurity in fintech, its impact on the cybersecurity landscape and the need for proac-tive defense strategies. However, opportunities exist to delve deeper into the methodologi-cal approaches employed within these studies. Critically examining the assumptions, limitations, and potential biases inherent in the reviewed literature can offer a more nu-anced understanding of the field and pave the way for future research directions. Cybersecurity and data privacy concepts and definitions

Defining some key concepts is important to understand the challenges and considerations surrounding cybersecurity and data privacy in the fintech world.

Threat landscape: The Fintech sector is continuously experiencing a wide range of evolving and diverse threats that pose significant risks to the security and privacy of sensitive data. These include cyber-attacks, data breaches, compliance issues with regulations, and new technologies introducing vulnerabilities.

Risk management: It includes the systematic identification, analysis, evaluation, and reduction of potential vulnerabilities and threats to guarantee a strong security infrastructure. Strict protocols for privacy management involve in-depth data protection within complex financial processes by methodically identifying risks, analyzing vulnerabilities, and evaluating threats to ensure effective security measures., and maintaining strict privacy protocols for sensitive data within fintech organizations. (Uddin et al., 2020)

Encryption: Converting sensitive data into unreadable code to prevent unauthorized access using encryption techniques and algorithms. This helps in ensuring that only authorized individuals or systems with the proper decryption key can access and understand the information, thus safeguarding it from potential security breaches.

Authentication: The process of verifying the identity of users or devices to ensure only authorized access to sensitive information and systems, often through multifactor authentication and security protocols. This includes confirming identities through biometric data, passwords, tokens, smart cards, or other secure methods while considering potential threats such as phishing attacks and social engineering tactics. (Varshney et al., 2020)

Security breach: Unauthorized access refers to gaining entry to sensitive data without proper authorization, while disclosure involves releasing this information to unauthorized individuals. Alteration pertains to any unauthorized changes made to the data, and destruction indicates the intentional or accidental elimination of sensitive data.

Compliance: Ensuring that fintech organizations strictly adhere to a comprehensive set of regulatory requirements and industry standards, meticulously designed to safeguard customer information and uphold the highest levels of data privacy. (Suryono et al., 2020)

Fintech companies create cutting-edge financial solutions and are recognized as important participants in the ecosystem. The end users utilizing these products are financial customers. The links to investments indicate the financial backing necessary for fintech projects to expand. Technology is a crucial component that emphasizes the need for advanced IT systems. The integration of traditional financial institutions represents the changing dynamic between fintech innovators and established finance organizations. Another crucial component is the government, which demonstrates the regulatory framework and its role in forming the fintech landscape.

Cybersecurity and Data Privacy Solutions

Cybersecurity threats keep evolving rapidly, requiring fintech companies to adapt and implement robust security measures constantly. The implementation of these measures is crucial for protecting against evolving threats. Some of the measures include:

• Encryption: Encrypting sensitive data in transit and at rest using solid algorithms like AES and RSA can significantly increase its security (Kavitha et al., 2022). Encryption helps to ensure that even if the data is accessed, it cannot be understood without the proper decryption key.
• Authentication: Implementing multi-factor authentication (MFA) protocols beyond traditional passwords can further strengthen access security. It may include biometric authentication, one-time passwords, or hardware tokens.
• Security Assessments: Regularly conducting penetration testing and vulnerability scanning helps identify and address security gaps before attackers can exploit them. Security assessments can also include risk assessments and security audits to evaluate the effectiveness of existing security measures.

Furthermore, emerging technologies like artificial intelligence (AI) and blockchain offer promising avenues for enhancing fintech security. AI-powered systems can analyze vast amounts of data to detect and prevent malicious activities in real-time. At the same time, blockchain technology can offer secure and tamper-proof data storage and sharing mechanisms. However, It is crucial to balance adopting these technologies with considerations for user privacy, responsible development, and ethical implications.

Common Cyber Security Threats for the Fintech

Phishing and social manipulation attacks are among the main reasons for security breaches due to human error. According to IBM's 2022 report on the Cost of a Data Breach, these attacks can also be very costly, with an average impact of USD 4.91 million for phishing and USD 4.10 million for social engineering. In such cases, attackers try to deceive users to obtain sensitive information like login credentials or banking details through email. Clicking on any compromised links or attachments in phishing emails can result in installing malicious software on the targeted computer system or lead users to a fraudulent webpage designed to collect login credentials. ((Oraca) & (Craciun), n.d)

Another significant risk financial technology companies face is the presence of malware and ransomware attacks. Malware pertains to harmful software designed to disturb or obtain unauthorized entry into computer systems. Such attacks can jeopardize user data, disrupt services, or facilitate unlawful access to financial systems. Attackers utilize malware to infiltrate systems and gain unauthorized access to information before deploying ransomware that encrypts the company's data. To prevent public exposure or avoid complete deletion of the company's database in some instances, threat actors demand payment in exchange for releasing it.

Due to the valuable customer and intellectual property information, it holds, ransomware groups find the financial services industry highly attractive. Furthermore, FinTech platforms are vulnerable to various malware, including viruses, ransomware, and spyware. The risk of exposing this data on the dark web and the subsequent harm to reputation and business prospects often forces many financial services organizations to give in to ransom demands even if official recommendations go against such practices.

Distributed Denial of Service (DDoS) Attacks are another threat that targets the resources of a FinTech platform, rendering it inaccessible to legitimate users. By flooding the system with a massive volume of traffic or requests, attackers disrupt services, cause financial losses, and damage the reputation of the targeted platform. To address these cybersecurity risks, the financial technology industry must prioritize the implementation of robust cybersecurity frameworks and standards.

As seen in the figure above, the source of cyber-attacks is different, and very often being distributed randomly, it isn't very easy to identify the person or persons who generated the respective cyber-attack.

A few recent studies highlight the increasing risks and challenges faced by the FinTech industry in terms of cybersecurity. For instance, the Decentralized Finance (DeFi) Platform Nomad Bridge Exploit resulted in a loss of $11 million worth of cryptocurrency due to a smart contract vulnerability (Challenges of using artificial intelligence, 2024). The incident was that a vulnerability in the Nomad bridge, which allowed users to transfer funds be-tween different blockchain networks, was exploited by a malicious actor who drained the funds. The regulatory landscape was such that the Defi platform could not recover the stolen funds. The Nomad Bridge exploit exposed the security risks inherent in DeFi protocols and the need for stricter measures to ensure user asset safety and transparency within the DeFi ecosystem.

Another instance is the social engineering attack on Binance users, where Binance, a leading cryptocurrency exchange, experienced a breach resulting in the theft of over $40 million worth of Bitcoin. (Contributors, 2023). Hackers gained unauthorized access to user accounts through phishing techniques and were able to steal funds from unsuspecting users. While Binance is subject to regulations in certain jurisdictions, the global nature of cryptocurrency makes it challenging to enforce consistent security measures across all platforms and jurisdictions. The incident underscores the importance of user education and awareness to prevent falling victim to phishing attacks in the context of cryptocur-rency transactions.The two recent cases above highlight the evolving nature of cybersecurity threats in the fintech industry, particularly about cryptocurrency platforms and decentralized finance protocols. While regulations are continuously being developed to address these issues, fintech companies must stay proactive in implementing strong cybersecurity measures and educating users about potential risks to mitigate cybercrime threats in the financial technology industry.
