Why Mobile Security Section

Why Mobile Security Demands a Specialized Approach

Expanding Attack Surface

Every customer device is a potential entry point. From jailbroken phones to malware-infected tablets, the diversity of devices and OS versions creates countless security variables that traditional testing can't address.

Beyond App Security

Mobile protection requires a holistic approach: API security, device attestation, certificate pinning, and runtime protections must work in concert. A vulnerability in any layer compromises the entire system.

Regulatory Complexity

From PSD2 to open banking mandates, mobile channels must balance innovation with compliance. Security testing must validate both technical controls and regulatory requirements.

Mobile Security Vulnerabilities Section

Where Most Mobile Security Controls Fall Short

Insufficient App Hardening
Lack of obfuscation, anti-tampering, and runtime protections leave apps vulnerable to reverse engineering and modification
Weak Device Attestation
Poor implementation of device integrity checks allows compromised devices to access sensitive financial services
Insecure Local Storage
Sensitive data stored in plaintext or with weak encryption on device storage, accessible to malware or physical attacks
API Key Exposure
Hardcoded credentials and API keys in mobile apps provide direct access to backend systems and customer data
Certificate Pinning Gaps
Missing or improperly implemented certificate pinning enables man-in-the-middle attacks on financial transactions
Mobile Security Risks

The Risks We Uncover

Mobile banking apps face new security threats every day. We test these apps to find dangerous problems that could hurt banks and their customers. These are the most common ways hackers try to break in and steal money or personal information.
