M7: Insufficient Binary Protections – OWASP Mobile Top 10 – Best Practices


The OWASP (Open Web Application Security Project) Top 10 Mobile report has highlighted a critical vulnerability: Insufficient Binary Protections. Mobile applications, being the digital backbone of our daily lives, store and process vast amounts of sensitive information. To understand this threat, let’s unravel what exactly insufficient binary protections entail.

What is Insufficient Binary Protections?

Binary Protection: In the realm of mobile applications, binary refers to the compiled form of the application’s source code. Binary protections, therefore, involve implementing security measures to safeguard this compiled code from various forms of exploitation and attacks.

Insufficiency Unveiled: When we talk about insufficient binary protections, we’re addressing the lack of robust security measures to defend the binary code of a mobile application. This vulnerability exposes the application to a spectrum of risks, potentially compromising the confidentiality, integrity, and availability of the application and its data.

Risks Associated with Insufficient Binary Protections
  1. Code Tampering:
    • Risk: Attackers can tamper with the application’s binary code, altering its functionality or injecting malicious code.
    • Example: Modifying a mobile game’s binary to unlock premium features without payment.
  2. Reverse Engineering:
  3. Runtime Attacks:
    • Risk: Insufficient protections expose the application to runtime attacks, where attackers inject and execute malicious code during the app’s execution.
    • Example: Exploiting a vulnerability to inject code that steals user credentials during the app’s operation.
  4. Insecure Data Storage:
    • Risk: Without proper binary protections, stored data within the application may be vulnerable to unauthorized access.
    • Example: Extracting sensitive user information from a healthcare app’s improperly secured local storage.
  5. API Security Risks:
    • Risk: Insufficient binary protections can extend vulnerabilities to the communication between the mobile app and back-end servers, risking data manipulation or unauthorized access.
    • Example: Intercepting API calls from a financial app and manipulating transaction data.
Responding to the Insufficient Binary Protections Challenge

To mitigate the risks associated with insufficient binary protections, a proactive and multifaceted approach is essential:

  1. Code Obfuscation:
    • Employ techniques like code obfuscation to make the reverse engineering process more challenging for attackers.
  2. Binary Hardening:
    • Implement measures such as stack protection and address space layout randomization (ASLR) to fortify the application against runtime attacks.
  3. Secure Data Storage:
    • Utilize encryption for sensitive data stored within the application, coupled with secure key management practices.
  4. API Security Measures:
    • Implement secure communication protocols and authentication mechanisms to protect APIs from exploitation.
  5. Continuous Monitoring and Response:

Insufficient binary protections expose mobile applications to a plethora of security risks, jeopardizing user data and the overall integrity of the application. Understanding the nature of this threat and responding with comprehensive security measures is crucial in building secure mobile applications that stand up to evolving cyber threats. Developers and organizations must ensure the implementation of robust binary protections to ensure the safety and privacy of users in an increasingly interconnected digital landscape.
