Attack Tree Path: 1. Exploit Inter-RIB Communication [HIGH RISK]

  • Description: This is the most significant attack vector, leveraging the core communication mechanism of RIBs. Attackers aim to intercept, modify, or inject messages to achieve their goals.

  • Attack Vectors:

    • Intercept RIB Messages [CRITICAL]
      • Description: Gaining access to the messages exchanged between RIBs.
      • Sub-Vectors:
        • Hook into Message Passing Mechanism (e.g., using Frida) [CRITICAL]
          • Description: Using tools like Frida (on Android/iOS) or similar techniques to intercept messages at the application level, bypassing network-level security.
          • Likelihood: Medium
          • Impact: High
          • Effort: Medium
          • Skill Level: Intermediate
          • Detection Difficulty: Hard
        • Exploit Weaknesses in Custom Message Serialization/Deserialization [CRITICAL]
          • Description: If custom serialization/deserialization is used, exploiting vulnerabilities in this process (e.g., insecure deserialization leading to code execution).
          • Likelihood: Medium (if custom and poorly implemented)
          • Impact: High (potential for RCE)
          • Effort: High
          • Skill Level: Advanced
          • Detection Difficulty: Hard
    • Modify RIB Messages in Transit (if integrity checks are missing) [CRITICAL]
      • Description: Altering the content of messages after interception to manipulate data or application state. Relies on the absence of integrity checks.
      • Likelihood: Medium (depends on interception success)
      • Impact: High
      • Effort: Medium
      • Skill Level: Intermediate
      • Detection Difficulty: Medium (easier with integrity checks)
    • Inject Forged RIB Messages (AND) [HIGH RISK]:
      • Description: Creating and sending fake messages to trigger unintended actions or state changes.
      • Sub-Vectors:
        • Bypass Message Authentication/Validation (if any) [CRITICAL]
          • Description: Circumventing any existing security measures that verify the authenticity or validity of messages.
          • Likelihood: Medium (if authentication is weak/missing)
          • Impact: High
          • Effort: Medium
          • Skill Level: Intermediate
          • Detection Difficulty: Medium (easier with authentication)
        • Craft Valid Message Payloads that Trigger Undesired State Changes [CRITICAL]
          • Description: Constructing message payloads that, while syntactically valid, cause the application to behave in a way that benefits the attacker.
          • Likelihood: Medium
          • Impact: High
          • Effort: Medium
          • Skill Level: Intermediate
          • Detection Difficulty: Medium

Attack Tree Path: 2. Gain Unauthorized Access to a RIB's Scope [HIGH RISK]

  • Description: Accessing data and functionality within a RIB's scope that should be restricted.

  • Attack Vectors:

    • Bypass Scope Access Controls (if improperly implemented) [CRITICAL]
      • Description: Exploiting flaws in the implementation of scope access controls to gain access to data or functionality within another RIB's scope.
      • Likelihood: Medium
      • Impact: High
      • Effort: Medium
      • Skill Level: Intermediate
      • Detection Difficulty: Medium

Attack Tree Path: 3. Directly Modify RIB State [HIGH RISK]

  • Description: Bypassing the intended communication and state management mechanisms to directly alter the internal state of a RIB.

  • Attack Vectors:

    • Exploit Weaknesses in State Management Logic (AND):
      • Sub-Vectors:
        • Bypass State Validation Checks (if any) [CRITICAL]
          • Description: Circumventing checks that are in place to ensure the validity of state transitions.
          • Likelihood: Medium (if validation is weak/missing)
          • Impact: High
          • Effort: Medium
          • Skill Level: Intermediate
          • Detection Difficulty: Medium
