Introduction
Mobile apps have become ubiquitous daily, with financial transactions and personal information relying heavily on them. However, the rise of cyber threats has questioned these apps' security, especially for the BFSI industry, which heavily relies on mobile banking apps. This makes mobile banking security testing even more crucial for developers to prioritize. Regular banking application testing can detect and mitigate vulnerabilities, save time and costs, help comply with security standards and regulations like HIPAA, PCI-DSS, etc., and ultimately protect against cyberattacks while driving business growth even during the economic downturn.
This blog discusses confidentiality security and its role in protecting mobile banking applications against data breaches.
Why Is Safeguarding Mobile Banking Apps from Vulnerabilities Crucial?
Mobile banking apps' vulnerabilities can be attributed to one of the five groups listed below.
Design Flaws
Security breaches can result from design errors and weak implementation during development. For instance, poor session management in a mobile application can lead to cookie manipulation bypassing authentication. This highlights the need for effective software testing in financial services.
Errors in Application Deployment
The customer's insufficiently planned application installation and lack of knowledge of computer infrastructure can result in errors, such as debug accounts/passwords not being deleted and version control errors. Therefore, an efficient banking application testing strategy is essential to identify and prevent such errors.
Coding Gaffes
Coding errors can compromise application functionality and lead to unintended actions. Vulnerabilities arise from buffer overflows, format string errors, and race conditions. Various publications have highlighted that coding errors are the most frequent cause of vulnerabilities. A proper mobile banking security testing method aids in detecting and preventing coding errors.
Faulty Communication
To function fully, mobile apps must connect to external sources like NFC, Bluetooth devices, servers, authorization mechanisms, and authentication tokens. However, this communication can expose sensitive data and pose a security risk. Banking application testing is crucial to address these security vulnerabilities.
Inadequate QC and Application Testing
Security vulnerabilities cannot be addressed only in final testing. Banking application testing must include security considerations throughout the process. Regular testing should cover both everyday scenarios and potential attack scenarios.
What Are the Most Prominent Fraud Cases in Mobile Banking?
Fake bank
Mobile banking security researchers detect and prevent app-based Trojans, malware, fake banking apps, phishing attacks, and brute force attacks that affect mobile banking apps. One such spyware, FakeBank, copies verification codes sent to customers by the bank and sends them to hackers.
App-based Trojans
Mobile banking fraud includes app-based trojans, often found in downloaded tools or games from unofficial sources. Trojans can spring to life when a banking app is launched, creating a pop-up overlay on the login page. Deploying proper software testing in financial services strategy can help prevent these attacks.
Svpeng
A senior malware analyst at Kaspersky, Roman Unuchek, found a new version of the mobile banking trojan Svpeng. This dangerous malware can hide behind other apps, conduct financial transactions, access contacts, make calls, and gain administrator rights.

Security Tactics for Ensuring Robust Banking App
Although there are valid security concerns with online banking, mobile banking is way more secure than web banking due to the closed nature of phone operating systems compared to computers. The rapid popularity of mobile banking, fueled by the current economic recession and people's desire for a more hands-on approach to managing their finances, requires unparalleled security for mobile banking apps.
Here are some banking application security practices to ensure the efficiency, accuracy, and reliability of mobile banking apps while keeping the app testing budget in check during the global recession:
1. Multi-factor Authentication
To ensure security, more than a single password submission is required to access a customer's bank account. To enhance mobile banking security, it is advisable to implement a multi-factor or two-factor authentication process. This can include using generated one-time passwords or biometric authentication methods like fingerprints, which add an extra layer of protection and reduce the risk of deception. Regular mobile banking security testing should also be performed to ensure effective security measures.
2. End-to-end Encryption
Two parties are always involved in digital transactions - the sender and the receiver. This occurs frequently in everyday transactions through mobile apps or financial payment gateways, with key players being customers, retailers, payment brands, issuing banks, etc. Billions of dollars worth of confidential data are exchanged daily, making internet purchases a target for cybercriminals.
Businesses must encrypt transactions to protect consumers. End-to-end encryption provides secure data transfer and stability and is responsible for conducting safety checks and surveys. It is essential for software testing in financial services to protect businesses from fraud and unethical behavior.
3. Direct Text and Email Notifications
A mobile banking app provides customers convenient access to text messages and email, and its real-time notification feature enables instant notification of transactions. For instance, customers receive an SMS whenever their card is swiped, allowing them to quickly detect any unauthorized activity and take action to prevent fraud.
On-the-spot notifications enable users to monitor their accounts and promptly respond to potential security threats. A proper banking application testing method is necessary to ensure these security features' reliability.
4. Detailed Analysis of Customer Behavior
Specialized software is available to monitor and analyze consumers' banking login locations and online account activities. This technology can detect potential errors, abnormal behavior, or unauthorized access to a mobile banking app and trigger further investigation. This investigation may take the form of an email or text alert to the customer or a call from the bank to confirm any suspicious activity. Effective banking application testing helps ensure these security measures' accuracy and reliability.
5. Paperless Banking
The banking sector has been revolutionized by technological advancements, ushering in an era of paperless banking. Digitalization has increased efficiency and transparency in managing bank accounts and transactions and shifted the focus toward robust security measures. As sensitive financial data is now stored digitally and accessed remotely, safeguarding this information against cyber threats has become paramount. To address these challenges, banks are actively seeking mobile banking security testing solution providers that deliver custom-built, high-security enterprise mobile solutions. These solutions ensure that banking applications are resilient against potential vulnerabilities while maintaining the seamless accessibility that modern banking demands.
6. Use of Authorized APIs
Using unauthorized APIs in mobile banking applications can significantly increase security risks, potentially exposing sensitive customer information to malicious actors. For instance, if an app caches authorization data locally to expedite repeated API calls, it may inadvertently create vulnerabilities that hackers can exploit. Unauthorized or improperly secured APIs may lack robust encryption, authentication, or access control mechanisms, allowing attackers to intercept data, impersonate legitimate users, or inject harmful commands into the system.
To mitigate these risks, mobile banking apps must integrate only authorized, centrally managed APIs and adhere to strict security protocols. These APIs should enforce secure authentication mechanisms, such as OAuth 2.0, and implement end-to-end encryption for data transmission. Regularly monitoring and updating APIs can help detect and patch vulnerabilities before they can be exploited. By adhering to these best practices, banks can safeguard sensitive financial data, ensuring their customers' information's integrity, security, and privacy.
7. Data Breach
Conducting thorough software testing in financial services is crucial to protecting personal and business information. A data breach can expose sensitive information, making developing secure mobile banking applications essential. With ready access to sensitive information such as passwords and account numbers, it is crucial to prioritize security in developing these applications.
8. Compliance with PSD2 Regulations
The PSD2 regulations tackle banking security issues such as reverse engineering and fund theft. They provide robust protection against fraud, improve digital security, and promote the use of digital documents. PSD2 supports the growth of open banking and enhanced online security, enabling stakeholders such as FinTechs, corporations, and clients to collaborate with banks for improved security. The regulations prioritize improved online protection for consumers, enhancing their overall experience with online payments.
9. Employ Secure Access
Effective mobile banking security testing protects customer information from theft and fraud. Using secure internet connections and technologies like HTTPS enhances security during mobile transactions. Financial institutions must balance convenience with security risks to ensure customers a mobile banking experience.
