What is mobile app fraud?
Mobile app fraud comprises deceitful tactics that aim to exploit legitimate apps, deceive users, and illicitly generate revenue within the mobile app ecosystem. These fraudulent activities specifically target a range of stakeholders, including users who download apps from the App Store or Play Market, as well as developers of genuine applications. The perpetrators frequently utilize fraudulent apps that closely resemble legitimate ones, leading users to unknowingly download them for malicious intents.
The proliferation of fraudulent mobile applications has led to a multitude of illicit activities, such as unauthorized transactions, data breaches, and the dissemination of malicious software. These deceitful apps not only inflict harm upon unsuspecting users but also damage the standing of legitimate applications, resulting in financial losses for both developers and advertisers. In light of the existence of fraudulent apps within reputable marketplaces like the App Store or Play Market, it is imperative for all parties involved to adopt a proactive and vigilant approach to ensure the integrity and security of the mobile app ecosystem.
How is Mobile app fraud or malicious mobile activity detected?
The implementation of a comprehensive and sophisticated detection system that combines automated tools and expert human analysis enables stakeholders in the mobile ecosystem to enhance their defense against fraud and malicious activities. It is crucial to acknowledge that the landscape of mobile app fraud is constantly changing, which underscores the importance of continuous vigilance and the ability to adapt to emerging threats.
Device fingerprinting:
Device fingerprinting is a technique that entails gathering comprehensive data regarding the user’s device, including but not limited to the operating system version, device type, and IP address. This valuable information can subsequently be utilized to detect and prevent fraudulent activities, such as instances in which a solitary device is employed to generate numerous accounts or when a device operates from a location divergent from the user’s account address.
Runtime Application Self-Protection (RASP) security is a crucial technology that enhances the security posture of mobile applications by actively detecting and responding to threats in real-time, during the application’s execution or runtime.
Below is an overview of how RASP security works to protect customers and mobile apps from various threats, including tampering, illegal modifications, and unknown threats:
Real-time Monitoring for Traffic Analysis:
Recognizing non-human traffic, rapid surges, or unusual patterns that are typically associated with bots or automated processes.
Active Threat Monitoring:
- Real-Time Protection: Appsealing RASP actively monitors the app’s behavior and user interactions during runtime. It can instantaneously identify and mitigate known and unknown threats.
- Internal Monitoring: Unlike perimeter defenses, RASP works from within the app, offering more detailed insight into the application’s runtime behavior and data flow.
Behavior Analysis:
- User Behavior: Analyzing patterns of user interaction with apps to identify anomalies indicative of fraud.
- Device Behavior: Monitoring device characteristics and behaviors that deviate from the norm, suggesting potential malicious activity.
Traffic Analysis:

- It stores data within the app or on the device and should also be encrypted to protect it if the device is lost or compromised.
2. Authentication & Authorization:
Authentication is the process that diligently verifies the identity of users, employing various methods such as credentials, biometrics, or even multi-factor authentication. In contrast, authorization serves as a crucial procedure that bestows or withholds access permissions to distinct resources and functions within the application, solely contingent upon the authenticated user’s profile. In other words,
- Authentication: Verifies the identity of users accessing the app, often through credentials, biometrics, or multi-factor authentication mechanisms.
- Authorization: Controls user access to various app features and data, granting permissions based on predefined roles or access levels.
3. Code Obfuscation & Integrity Checks:
Code obfuscation is the process of transforming the source code of an application into a highly convoluted and intricate format, rendering it arduous to decipher and comprehend. This technique serves to heighten the complexity of reverse engineering endeavors, thereby bolstering the overall security of the application.
Additionally, integrity checks play a crucial role in guaranteeing the sanctity of the app’s code, thereby fortifying it against any potentially malicious alterations. In other words,
- Code Obfuscation: Makes the application’s source code more difficult to read and understand, hindering reverse engineering attempts by malicious actors.
- Integrity Checks: Validates that the application’s code has not been tampered with or modified, protecting against code injection or alteration attacks.
4. Secure Communication:
Secure communication ensures all data exchanges between the app and servers occur securely. By utilizing secure communication protocols like HTTPS (SSL/TLS), data transmitted is encrypted, providing confidentiality and integrity during transit, and protecting against potential interceptors and eavesdroppers. Implements secure communication protocols like HTTPS (SSL/TLS) to encrypt data transmitted between the app and servers, protecting against man-in-the-middle attacks.
5. Input Validation:
Input validation is an essential security measure implemented to thwart the infiltration of malevolent data into the application. Through the meticulous process of validating, sanitizing, and filtering user inputs, the application can effectively safeguard itself against a plethora of injection attacks, thereby upholding the integrity and security of the data.
It ensures that the app properly validates and sanitizes user inputs to prevent injection attacks, such as SQL injection or cross-site scripting (XSS).
6. Runtime Protection:
Runtime application security protection involves monitoring and securing the application while it’s actively running. This component safeguards against dynamic threats like code injections and function manipulations, offering real-time defense against exploits that attempt to compromise the app during operation.
Employs security measures to protect the application during its runtime, preventing exploits like code injection, tampering, or analysis from being conducted on running applications.
