Attack Tree Path: [Manipulate Application State]***

  • Description: The overarching objective of the attacker. Successful manipulation leads to a significant compromise of the application.
  • Likelihood: (Dependent on the success of sub-nodes)
  • Impact: Very High
  • Effort: (Dependent on the success of sub-nodes)
  • Skill Level: (Dependent on the success of sub-nodes)
  • Detection Difficulty: (Dependent on the success of sub-nodes)

Attack Tree Path: [Exploit State Management Logic] (HIGH)

  • Description: Attacks targeting the core of how MvRx manages the application's state. This is a high-risk area due to the prevalence of input vectors and the potential for logic errors.
  • Likelihood: High
  • Impact: High to Very High
  • Effort: Low to Medium
  • Skill Level: Intermediate to Advanced
  • Detection Difficulty: Medium

Attack Tree Path: [Invalid State Transitions] (HIGH)

  • Description: Attempts to force the application into an invalid or unexpected state, violating the intended state machine logic.
  • Likelihood: Medium
  • Impact: Medium to High
  • Effort: Low to Medium
  • Skill Level: Intermediate
  • Detection Difficulty: Easy (with validation) / Medium (without)

Attack Tree Path: [Fragment Argument Passing] (HIGH)

  • Description: Exploiting how arguments are passed to Fragments. If arguments are used to initialize or update state and are not properly validated, an attacker can inject malicious data.
  • Likelihood: Medium
  • Impact: Medium to High
  • Effort: Low
  • Skill Level: Intermediate
  • Detection Difficulty: Easy (with validation) / Medium (without)

Attack Tree Path: [ViewModel Initialization State] (HIGH)

  • Description: Similar to Fragment arguments, but focusing on the initial state set up within the ViewModel. If this initial state is derived from external sources without validation, it's vulnerable.
  • Likelihood: Medium
  • Impact: Medium to High
  • Effort: Low
  • Skill Level: Intermediate
  • Detection Difficulty: Easy (with validation) / Medium (without)

Attack Tree Path: [Fragment/ViewModel Subscription] (HIGH)

  • Description: If external data sources are compromised, this becomes a high-risk path.
  • Likelihood: Low to Medium
  • Impact: High
  • Effort: Medium
  • Skill Level: Advanced
  • Detection Difficulty: Medium

Attack Tree Path: [Unintended State Updates] (HIGH)

  • Description: Triggering state updates that should not occur, or with incorrect data, even if the resulting state itself isn't inherently "invalid."
  • Likelihood: Medium
  • Impact: Medium to High
  • Effort: Low to Medium
  • Skill Level: Intermediate
  • Detection Difficulty: Easy (with validation) / Medium (without)

Attack Tree Path: [Bypass State Validation] (HIGH)

  • Description: Circumventing the validation logic that is intended to ensure the integrity of the application's state. This is critical because it removes a primary defense.
  • Likelihood: Low (if validation is good) / Medium (if weak)
  • Impact: High
  • Effort: Medium
  • Skill Level: Intermediate to Advanced
  • Detection Difficulty: Medium (requires code review and testing)
