Attack Tree Analysis for libp2p/go-libp2p

Objective: To disrupt the availability, integrity, or confidentiality of the application's p2p network and/or its connected peers.

Attack Tree Path: Disrupt Availability, Integrity, or Confidentiality of the Application's P2P Network/Peers

  • Description: This is the overarching goal of the attacker. It encompasses any action that negatively impacts the application's p2p functionality.
  • Criticality: This is the root node and, by definition, critical.

Attack Tree Path: Denial of Service (DoS)

  • Description: Attacks aimed at making the application or its p2p network unavailable to legitimate users.
  • Criticality: Critical due to the high impact and relative ease of some DoS attacks.
  • Sub-Goals:
    • [[Resource Exhaustion]]: Consume resources (CPU, memory, bandwidth, connections) to make the system unresponsive.
      • Criticality: A common and effective attack vector.
      • Sub-Goal:
        • [[Flood]]: Send a large volume of requests or data to overwhelm the target.
          • Likelihood: Medium to High
          • Impact: High to Very High
          • Effort: Low to Medium
          • Skill Level: Novice to Intermediate
          • Detection Difficulty: Easy to Medium
          • Mitigation: Implement robust rate limiting, connection limits, and resource management. Monitor resource usage. Use circuit breakers.
    • [Network Disruption]: Prevent nodes from communicating with each other.
      • Sub-Goal:
        • [Block/Isolate]: Exploit routing or discovery to prevent nodes from connecting.
          • Likelihood: Low to Medium
          • Impact: High to Very High
          • Effort: Medium to High
          • Skill Level: Advanced
          • Detection Difficulty: Medium to Hard
          • Mitigation: Use trusted bootstrap nodes, static peer lists, or secure discovery protocols. Validate peer IDs and addresses. Monitor network topology.
    • [Exploit Vulnerabilities]: Leverage bugs in go-libp2p or its dependencies.
      • Sub-Goal:
        • [Crash]: Send crafted messages to trigger a crash.
          • Likelihood: Low to Medium
          • Impact: High
          • Effort: Medium to High
          • Skill Level: Advanced to Expert
          • Detection Difficulty: Medium
          • Mitigation: Fuzz testing, robust error handling, keep software up-to-date.

Attack Tree Path: Compromise Confidentiality

  • Description: Attacks aimed at gaining unauthorized access to data exchanged between peers.
  • Criticality: Critical due to the potential for sensitive data exposure.
  • Sub-Goals:
    • [[Eavesdropping]]: Passively listen to network traffic.
      • Criticality: A fundamental threat to confidentiality.
      • Sub-Goal:
        • [[Sniff]]: Capture network traffic without authorization.
          • Likelihood: High (if unencrypted)
          • Impact: Medium to High
          • Effort: Low
          • Skill Level: Novice
          • Detection Difficulty: Very Hard
          • Mitigation: Enforce authenticated encryption for all communication. This is the primary and most crucial defense.

Attack Tree Path: Protocol Misuse

  • Sub-Goal:
    • [Abuse]: Use a protocol in unintended ways to cause issues.
      • Likelihood: Medium
      • Impact: Medium to High
      • Effort: Medium
      • Skill Level: Intermediate to Advanced
      • Detection Difficulty: Medium to Hard
      • Mitigation: Clearly define and enforce intended protocol behavior. Implement input validation and sanitization. Conduct thorough security reviews of custom protocols.
