Banking, Financial Services, and Insurance Apps Security

BFSI applications must continuously align with evolving regulatory and security requirements while protecting sensitive customer and financial information. Meeting these requirements requires security controls across application testing, data protection, runtime security, fraud prevention, and monitoring.

Recommended controls: Continuous security assessments, vulnerability management, runtime monitoring, audit-ready reporting, and security controls aligned with applicable RBI, SEBI CSCRF, NPCI, and OWASP MASVS requirements.

Mobile banking applications rely on trusted SIM and device associations to help verify the legitimacy of a user and their transactions. Attackers can target these binding mechanisms through SIM-related attacks, SMS hooking, device compromise, or application-level manipulation to gain unauthorized access.

Recommended controls: Hardware-backed attestation, server-side validation of RASP controls, application integrity checks, runtime threat detection, and SMS hooking detection.

A rooted, jailbroken, or malware-infected device can weaken the protections an application normally relies on. Attackers may gain visibility into application processes, manipulate data, or interfere with authentication and transaction flows.

Recommended controls: Device integrity validation, root/jailbreak detection, emulator detection, malware indicators, device-risk assessment, and runtime enforcement.

Sensitive customer and financial data can leak through insecure local storage, logs, screenshots, backups, exposed APIs, or unsafe platform interactions. Once data leaves the intended security boundary, the impact can extend from privacy loss to fraud and regulatory exposure.

Recommended controls: Secured data handling, hardened APIs, controlled platform interaction, and runtime safeguards.

Once attackers understand an application's internal logic, they can identify security checks, endpoints, sensitive strings, and exploitable workflows. The more valuable the application's logic, the greater the incentive to analyze the binary.

Recommended controls: Code encryption, anti-static analysis, anti-debugging, and application shielding.

Attackers through phishing, malware, or compromised devices gain unauthorized access to banking and financial accounts. Once an account is compromised, attackers may attempt to access sensitive information, exploit stolen credentials, change account details, or initiate fraudulent transactions.

Recommended controls: Strong authentication controls, device and session validation, app and device integrity detection, risk-based checks, red teaming assessments, and runtime threat protection.

Dynamic instrumentation lets attackers observe and alter application behavior while it is running. Functions, memory, API calls, SMS or security checks can be modified to bypass controls or influence protected workflows.

Recommended controls: Anti-hooking, anti-debugging, SMS spoofing detection instrumentation detection, runtime integrity verification, and active runtime response.

Attackers can modify a legitimate banking or fintech application, bypass built-in checks, and redistribute a manipulated build. This creates a trusted-looking entry point for abusing application functionality or harvesting sensitive information.

Recommended controls: Application integrity checks, anti-tampering, repackaging detection, runtime code verification, and application shielding.

Malicious apps can exploit the mobile environment to interfere with sensitive screens or capture information presented to the user. These attacks become more dangerous when they occur during authentication or high-risk financial actions.

Recommended controls: Overlay detection, keylogger detection, secure UI controls, screen-protection measures, controlled platform interactions, and runtime threat detection.
