Hacking Mobile Platforms

Correct Answer: SQL Injection through QR code payloads

The scenario describes a mobile app that creates QR codes with embedded SQL commands passed directly to the backend database for validation. This is a classic SQL Injection vulnerability scenario. SQL Injection occurs when untrusted data is sent to an interpreter as part of a command or query, allowing attackers to execute unintended commands or access unauthorized data. In this case, the QR codes contain SQL commands that are passed directly to the database with apparently no proper sanitization or parameterization. This makes "SQL Injection through QR code payloads" the correct answer because the vulnerability specifically involves SQL commands embedded in QR codes. The other options are incorrect: - Cross-Site Request Forgery requires tricking a user into executing unwanted actions on a web application where they're already authenticated. This doesn't match the described vulnerability of SQL commands in QR codes. - QR code spoofing with malformed authentication tokens is about creating fake QR codes, not about embedding SQL commands in legitimate QR codes generated by the app. - Session hijacking involves capturing or predicting session identification to gain unauthorized access. While security issues exist in the scenario, the specific problem described is SQL Injection, not session management.

Correct Answer: Implement application containerization to isolate the banking app and its data from personal apps

The best strategy for this scenario is implementing application containerization to isolate the banking app and its data from personal apps. This approach creates a secure, isolated environment for the banking application on employees' personal devices. Containerization separates the banking app and its data from other personal applications, ensuring that sensitive development credentials and test data remain protected even when used on personal devices. This separation provides appropriate security boundaries while still allowing employees to test the application. Regarding the other options: Creating a mobile application management policy that blocks screenshots and copy/paste would provide some security benefits but doesn't address the fundamental issue of separating company data from personal data on the device. Deploying a mobile threat defense solution focuses on monitoring network traffic, which doesn't solve the core problem of protecting development credentials and data stored on personal devices. Configuring remote attestation for device integrity verification would help ensure devices aren't compromised but doesn't provide the data separation needed when mixing personal and sensitive company applications on the same device.

Correct Answer: Code Signing Bypass

Code Signing Bypass is the correct answer because Frida is a dynamic instrumentation toolkit that can be used to inject JavaScript code into running iOS applications by bypassing Apple's code signing mechanism. This allows security researchers and pentesters to analyze and manipulate app behavior at runtime. When testing iOS applications, Frida works by attaching to running processes and injecting a JavaScript engine that enables runtime manipulation of the application. This technique specifically targets and bypasses the code signing protections that normally prevent unauthorized code execution. The other options are incorrect: Transport Layer Security Tunneling relates to network traffic encryption rather than code injection mechanisms. Secure Enclave Privilege Escalation refers to attacking the hardware security module that handles sensitive cryptographic operations, not application code injection. Application Sandbox Protection Layer Manipulation is too broad and imprecise. While Frida does operate across sandbox boundaries, the specific mechanism being exploited is the code signing protection, which prevents unauthorized code from running on iOS devices.
