Attack Tree Analysis for mitmproxy/mitmproxy

Objective: Exfiltrate sensitive data, manipulate application behavior, or inject malicious code into the application's traffic by exploiting mitmproxy's interception and modification capabilities.

Attack Tree Path: High-Risk Path: Sniff Traffic -> Capture Credentials

  • Description: This attack path involves passively intercepting network traffic to capture user credentials (usernames and passwords).
  • Attack Steps:
    • Sniff Traffic: The attacker uses mitmproxy to intercept network traffic between the client and the server.
    • Capture Credentials {CRITICAL NODE}: The attacker extracts usernames and passwords from the intercepted traffic, often from HTTP requests (if TLS is not properly enforced) or by breaking weak encryption.
  • Likelihood: High (if TLS/SSL is not properly enforced or if the attacker can compromise the certificate trust chain).
  • Impact: High (leads to account compromise, allowing the attacker to impersonate the user).
  • Effort: Very Low (mitmproxy makes traffic interception easy).
  • Skill Level: Novice (basic understanding of mitmproxy and network traffic).
  • Detection Difficulty: Medium (requires network traffic analysis and potentially decryption).
  • Mitigation:
    • Enforce strong TLS/SSL encryption with proper certificate validation.
    • Use multi-factor authentication.
    • Avoid sending credentials in plain text.
    • Monitor network traffic for suspicious activity.

Attack Tree Path: High-Risk Path: Sniff Traffic -> Capture API Keys

  • Description: This attack path involves passively intercepting network traffic to capture API keys or other sensitive tokens.
  • Attack Steps:
    • Sniff Traffic: The attacker uses mitmproxy to intercept network traffic.
    • Capture API Keys {CRITICAL NODE}: The attacker extracts API keys or other authentication tokens from the intercepted traffic.
  • Likelihood: Medium (depends on how API keys are transmitted).
  • Impact: High (can grant the attacker access to sensitive APIs and data).
  • Effort: Very Low (passive sniffing).
  • Skill Level: Novice.
  • Detection Difficulty: Medium (requires traffic analysis and potentially decryption).
  • Mitigation:
    • Use secure methods for transmitting API keys (e.g., HTTPS with proper certificate validation).
    • Implement API key rotation and revocation mechanisms.
    • Monitor API usage for suspicious activity.

Attack Tree Path: High-Risk Path: Modify Traffic -> Inject Malicious Scripts

  • Description: This attack path involves actively modifying intercepted traffic to inject malicious scripts into web pages or API responses.
  • Attack Steps:
    • Modify Traffic: The attacker uses mitmproxy's scripting capabilities to alter the content of requests or responses.
    • Inject Malicious Scripts {CRITICAL NODE}: The attacker inserts JavaScript or other code into web pages, enabling attacks like Cross-Site Scripting (XSS) or session hijacking.
  • Likelihood: Low (requires finding an injection point and crafting a suitable payload).
  • Impact: High (can lead to client-side compromise, data theft, and session hijacking).
  • Effort: Medium (requires crafting malicious scripts and understanding the application's behavior).
  • Skill Level: Intermediate (requires knowledge of web security vulnerabilities and scripting).
  • Detection Difficulty: Hard (modified traffic may appear legitimate; requires client-side security analysis).
  • Mitigation:
    • Implement robust input validation and output encoding.
    • Use Content Security Policy (CSP) to restrict the sources of scripts.
    • Regularly scan for XSS vulnerabilities.
    • Monitor client-side behavior for anomalies.

Attack Tree Path: High-Risk Path: Exploit mitmproxy Configuration/Scripting -> Insecure Configuration -> Disable TLS/SSL

  • Description: This path involves exploiting a misconfiguration of mitmproxy to disable TLS/SSL verification, allowing for easy interception of encrypted traffic.
  • Attack Steps:
    • Insecure Configuration: The mitmproxy instance is configured insecurely, often due to user error or negligence.
    • Disable TLS/SSL {CRITICAL NODE}: TLS/SSL verification is disabled, allowing the attacker to intercept and decrypt traffic without needing to compromise the certificate trust chain.
  • Likelihood: Low (users are generally aware of TLS/SSL importance, but mistakes happen).
  • Impact: Very High (exposes all intercepted traffic to the attacker).
  • Effort: Very Low (simple configuration change).
  • Skill Level: Novice.
  • Detection Difficulty: Easy (can be detected by checking the mitmproxy configuration).
  • Mitigation:
    • Never disable TLS/SSL verification in a production environment.
    • Regularly audit the mitmproxy configuration.
    • Use configuration management tools to enforce secure settings.

Attack Tree Path: High-Risk Path: Compromise mitmproxy Instance -> Physical/Network Access -> Gain Shell Access -> Modify mitmproxy Configuration

  • Description: This path involves gaining full control over the machine or container running mitmproxy, allowing the attacker to modify its configuration and behavior.
  • Attack Steps:
    • Physical/Network Access: The attacker gains physical access to the machine or compromises it over the network (e.g., through SSH, RDP, or a vulnerability).
    • Gain Shell Access {CRITICAL NODE}: The attacker obtains a command-line shell on the system.
    • Modify mitmproxy Configuration {CRITICAL NODE}: The attacker changes mitmproxy's settings to disable security features, enable malicious behavior, or redirect traffic.
  • Likelihood: Low (requires significant effort to gain access).
  • Impact: Very High (complete control over mitmproxy and potentially the host system).
  • Effort: High (requires network penetration or physical security bypass skills).
  • Skill Level: Advanced.
  • Detection Difficulty: Medium to Hard (depends on the security measures in place).
  • Mitigation:
    • Implement strong network security controls (firewalls, intrusion detection systems).
    • Secure the host system with strong passwords, regular patching, and host-based security software.
    • Monitor for unauthorized access attempts.
    • Use least privilege principles for user accounts.
    • Implement physical security measures to prevent unauthorized access to the machine.
