Attack Tree Path: Gain Unauthorized Access/Disrupt Application via ZeroTier

  • Description: This is the overarching goal of the attacker – to either gain unauthorized access to application resources/data or to disrupt the application's services by targeting the ZeroTier One integration.
    • Likelihood: N/A (This is the goal, not an attack step)
    • Impact: Very High
    • Effort: N/A
    • Skill Level: N/A
    • Detection Difficulty: N/A

Attack Tree Path: Compromise ZeroTier Network

  • Description: The attacker aims to gain control over the ZeroTier network itself, allowing them to manipulate network membership, configuration, or routing.
    • Likelihood: Variable (Depends on specific sub-attacks)
    • Impact: Very High (Complete control over network communication)
    • Effort: Variable
    • Skill Level: Variable
    • Detection Difficulty: Variable

Attack Tree Path: Join Network Illegitimately

  • Description: The attacker gains access to the ZeroTier network without proper authorization.
    • Likelihood: Medium to High
    • Impact: High (Unauthorized network access)
    • Effort: Variable
    • Skill Level: Variable
    • Detection Difficulty: Medium to Hard

Attack Tree Path: Social Engineering

  • Description: The attacker uses social engineering techniques (phishing, impersonation, etc.) to trick a legitimate user into revealing network credentials (Network ID, join token). * Likelihood: Medium to High * Impact: High * Effort: Low to Medium * Skill Level: Novice to Intermediate * Detection Difficulty: Medium

Attack Tree Path: Exploit Vulnerability in Join API

  • Description: The attacker exploits a vulnerability in the application's implementation of the ZeroTier join process. This could involve insecure exposure of the Network ID, a lack of proper validation, or an injection vulnerability. * Likelihood: Low to Medium (Depends on application design) * Impact: Very High * Effort: Medium to High * Skill Level: Intermediate to Advanced * Detection Difficulty: Hard

Attack Tree Path: Compromise Controller

  • Description: Attacker gains control over network controller. * Likelihood: Variable * Impact: Very High * Effort: Variable * Skill Level: Variable * Detection Difficulty: Variable

Attack Tree Path: Compromise Central

  • Description: Attacker gains control over ZeroTier Central. * Likelihood: Very Low * Impact: Very High * Effort: Very High * Skill Level: Expert * Detection Difficulty: Very Hard

Attack Tree Path: Compromise Moon

  • Description: Attacker gains control over custom Moon server. * Likelihood: Low to Medium * Impact: Medium to High * Effort: Medium to High * Skill Level: Intermediate to Advanced * Detection Difficulty: Medium to Hard

Attack Tree Path: Manipulate Network Configuration

  • Description: The attacker gains the ability to modify the ZeroTier network's configuration, potentially altering routing, access rules, or other settings.
    • Likelihood: Variable (Depends on specific sub-attacks)
    • Impact: High (Can disrupt or redirect network traffic)
    • Effort: Variable
    • Skill Level: Variable
    • Detection Difficulty: Variable

Attack Tree Path: Weak Authentication

  • Description: The attacker gains access to the network controller (ZeroTier Central or a self-hosted controller) by exploiting weak authentication mechanisms, such as default passwords, easily guessable credentials, or a lack of multi-factor authentication. * Likelihood: Medium * Impact: High * Effort: Low * Skill Level: Novice * Detection Difficulty: Medium
