What are the Cybersecurity Vulnerabilities confronting Fintech Apps?

 

cybersecurity-loopholes-in-fintech-applications

Traditional financial services have undergone a rapid and comprehensive transformation in the last few years with the adoption of fintech applications. These have brought convenience, better usability, and time and cost savings for the users. Consequently, instead of visiting the banks or financial institutions, users are able to carry out a series of transactions through the apps operable from their smartphones. These include paying utility bills, transferring funds, lending and personal finance, booking tickets for airlines, railways, movies, buying online groceries, among others.

However, notwithstanding the steady adoption of fintech applications by banking customers, there are several cybersecurity loopholes necessitating fintech application testing. Importantly, the integration of fintech applications with banking solutions has raised issues of data security. Further, the rapid growth of digital platforms such as devices, operating systems, and networks has introduced the possibilities for vulnerabilities in the whole system. These digital platforms face potential risks from various threat actors and can be exploited for financial gain.

Cybersecurity loopholes in Fintech applications

Given that fintech applications deal with banking transactions, they are increasingly targeted by threat actors using a host of techniques or malware. According to a BCG report, financial services firms are likely to be attacked 300 times more compared to other companies by cyber threat actors. Again, as per ImmuniWeb, the research firm, around 98% of the best fintech start-ups in the world face the risk of major cyberattacks. In such attacks, the various attack vectors used by cybercriminals include Distributed Denial of Service (DDoS) attacks, ransomware, and social engineering to gain access to critical and confidential data. The cybersecurity loopholes faced by fintech applications are:

Sharing of data: One of the major aspects of fintech applications involves sharing of data between traditional financial enterprises and modern digitally transformed organizations. This transmission of data between two entities following different business models and security protocols can be a source of cybersecurity issues to be exploited by threat actors. Hence, financial application testing should be a mandatory part of the build process wherein loopholes in integrations can be identified and fixed. In fact, fintech testing should check if the data accessed by the application throughout the SDLC is encrypted or not.

Integration with third-party APIs: The more integrations a fintech application has with third-party systems like payment gateways or digital wallets, the more it is likely to be exposed to threats. Since various systems are designed and developed differently, there may be compatibility issues during integration. This calls for stringent fintech app testing to ensure the total integration of third-party APIs and prevention of any compatibility issues.

Cross-platform malware infection: Fintech applications may use various digital platforms such as cloud services, smartphones, or websites from different vendors. This may allow threat actors to infect a platform with malware and propagate it to the other thereby creating a chain of cybersecurity risks. Further, since different platforms maintain different levels of cybersecurity measures and comply with different regulatory protocols, they may act as a conduit for malware. 

Cloud-based risks: Cloud services have become ubiquitous with various digital services using them to ensure better accessibility, scalability, speed, security, and availability of services. These digital services comprising digital wallets, mobile apps, websites, and payment gateways may use cheap or inefficient cloud services. With stringent QA testing in fintech, the security of cloud services and their interactions with digital services can be verified and validated. 

Digital identities: To provide an omnichannel experience to the customers, fintech applications are increasingly using biometric sensors such as fingerprint or iris scanners to authenticate users. In addition to biometrics, such apps use One Time Passwords (OTPs) for user authentication, which are better secured than screen patterns, PINs, or passwords. Even though digital identities have helped to strengthen the security of such apps they have become unwieldy and difficult to manage. Think of thousands of OTPs that need to be generated and stored in the system for authentication. Should these identities get stolen, cybercriminals can use them to get access to confidential data and financial information of customers. Hence, testing financial apps should leverage automation and advanced technologies like AI & ML to identify any outlier or missing pattern and prevent threat actors from acting.

Compliance failures: Fintech applications should comply with all regulatory requirements such as PCI DSS, PSD2, and hold licenses such as Electronic Money Institution and Payment Institution, etc. Financial services application testing can verify if the apps comply with industry mandated security standards, and in the process, prevent censure, penalties, and lawsuits. 

Conclusion

In the fast-paced digital environment, fintech applications are released with frequent regularity. However, since these have integrations with banking services, the need for implementing better security protocols like encryption or the use of biometrics becomes critical. Fintech testing of such applications can garner better trust from customers and other stakeholders and prevent threat actors from exploiting the vulnerabilities.

Discuss Test Orchestration and its Role in Achieving Optimal Quality of Software

Image
  In the DevOps approach of developing, testing, and delivering software applications, there is a need to accelerate testing within the constraints of budget and time. This entails automating the testing process as part of the testing strategy. In many cases, continuous test automation is often considered as a discrete step in the build pipeline rather than a sequence of steps. For any continuous testing strategy, all software applications need to pass through a series of tests before they pass muster in the crucible of quality. These may include unit testing, integration testing, functional testing, smoke testing, performance testing, security testing, and others. For DevOps QA testing, each of these tests should be subjected to automation to enhance quality, reduce test time, and improve the certainty of software behavior. However, merely automating the tests left, right, and center does not augur well when it comes to achieving an optimal quality level as well as minimizing the ...

How Customer Sentiment Analysis can Benefit Businesses

Image
  A customer may display varied emotions (positive or negative) while engaging with a brand. These emotions determine if the customer is likely to revisit the brand or junk it altogether. According to a McKinsey study, more than 85 percent of customers are likely to purchase from a brand again after having a positive customer experience. A negative customer experience, on the other hand, can reduce the number of customers by 70%. So, how do businesses know whether their customers are happy while engaging with their brand? Instead of merely depending on assumptions, the answer lies in analyzing customer sentiment. Customer sentiment analysis can let businesses know about the different emotions customers go through while dealing with a particular brand, product, or service. Customer experience insights can help brands offer more of the elements that make customers happy. Moreover, it can improve the customer satisfaction index, customer lifetime value, and customer loyalty, thereby ...

  The COVID-19 pandemic has dealt a body blow to the global economy, with scores of businesses ending up on the losing side. As governments scrambled to contain the spread of the pandemic through massive and prolonged lockdowns, most sectors of the economy took a hit, leading to job cuts, revenue losses, and the shredding of reputations. The pandemic has destroyed the livelihoods of millions of business enterprises trying to come to terms with a hitherto unseen situation. The blow came as a double whammy for everyone as the world was coping with a prolonged recessionary trend in the pre-pandemic era. However, with signs of the pandemic fading in many parts of the world, albeit unevenly, global economic growth is expected to be 4.9 percent in 2022 (Source: imf.org). The economic rebound, though robust, is expected to be uneven across countries and sectors. So, on one hand, we have seen companies across domains going out of business. Many managed to sustain themselves and sail throug...
