Attack Tree Path: 1. Exploit Device Connectivity [HR]

  • 1. Weak Device Credentials [HR] [CN]:

    • Description: Attackers exploit default or easily guessable credentials on IoT devices connected to the ThingsBoard platform.
    • Likelihood: High
    • Impact: Medium to High (Device control, pivot to ThingsBoard)
    • Effort: Very Low
    • Skill Level: Novice
    • Detection Difficulty: Medium
    • Mitigation:
      • Enforce strong, unique passwords for all devices.
      • Mandatory credential change upon initial setup.
      • Consider certificate-based authentication.
      • Regular credential audits.

  • 2. Unsecured Device Communication [HR]:

    • Description: Attackers intercept unencrypted communication between devices and ThingsBoard (e.g., HTTP, MQTT without TLS) to steal credentials or inject malicious commands.
    • Likelihood: Medium
    • Impact: High (Credential theft, command injection)
    • Effort: Low to Medium
    • Skill Level: Intermediate
    • Detection Difficulty: Hard
    • Mitigation:
      • Mandate encrypted communication (HTTPS, MQTT over TLS/SSL).
      • Use strong cipher suites and certificate validation.
      • Network segmentation.

Attack Tree Path: 2. Exploit ThingsBoard Core Vulnerabilities [HR]

  • 4. Unpatched ThingsBoard Instance [HR] [CN]:
    • Description: Attackers exploit known vulnerabilities in an outdated ThingsBoard installation. Public exploits may be readily available.
    • Likelihood: Medium
    • Impact: High to Very High (Full system compromise)
    • Effort: Low to Medium
    • Skill Level: Intermediate to Advanced
    • Detection Difficulty: Medium
    • Mitigation:
      • Strict patch management policy.
      • Monitor ThingsBoard security advisories.
      • Prompt updates (staging environment first).

Attack Tree Path: 3. Exploit ThingsBoard Authentication/Authorization [HR]

  • 10. Weak User Passwords (ThingsBoard Users) [HR] [CN]:
    • Description: Attackers crack weak passwords for ThingsBoard user accounts, gaining access to the platform's interface and functionality.
    • Likelihood: High
    • Impact: High (Full access to the ThingsBoard interface)
    • Effort: Very Low
    • Skill Level: Novice
    • Detection Difficulty: Medium
    • Mitigation:
      • Enforce strong password policies (length, complexity, expiration).
      • Account lockout policies.
      • Multi-factor authentication (MFA).

Attack Tree Path: Key High-Risk Paths (Recap):

  1. Device Compromise via Weak Credentials -> Pivot to ThingsBoard: Attackers first compromise a device using weak credentials (1), then potentially use unsecured communication (2) to gain further access or directly attack the ThingsBoard instance.
  2. Exploit Unpatched ThingsBoard Instance: Attackers directly exploit a known vulnerability in an unpatched ThingsBoard installation (4).
  3. Compromise ThingsBoard User Account via Weak Password: Attackers gain direct access to the ThingsBoard interface by cracking a user's weak password (10).
  4. Device compromise via Unsecured Communication -> Intercept Credentials -> Access Thingsboard: Attackers intercept credentials from unencrypted communication (2) and use them to access Thingsboard (potentially leveraging 10 if user also has weak password).
