Attack Tree Path: 1. Compromise Insomnia Installation/Configuration [CN]

  • Description: This is a critical node because gaining control over the Insomnia installation or its configuration files provides direct access to stored data (API keys, requests, environments, etc.).
  • High-Risk Paths:
    • 1.1 Local File Access to Insomnia Data [HR]
      • 1.1.1 Unprotected Config Files [HR] [CN]
        • Attack Vector: An attacker with local access (either directly or through another compromised application) exploits weak file system permissions on Insomnia's data directory to read sensitive configuration files.
        • Details:
          • Insomnia stores data in files (location varies by OS).
          • Weak permissions (e.g., world-readable) allow unauthorized access.
          • Attacker can read API keys, credentials, request history, and environment variables.
          • This could be combined with other attacks (e.g., malware) to gain initial local access.
    • 1.2 Weak/Default Credentials/Permissions [HR]
      • Attack Vector: An attacker exploits weak or default credentials used for Insomnia's data synchronization feature (if enabled) or for shared workspaces to gain unauthorized access to sensitive data.
      • Details:
        • If Insomnia uses a cloud service for sync, weak credentials for that service can be compromised.
        • Shared workspaces with overly permissive access controls can be exploited.
        • Attacker gains access to synchronized data, potentially across multiple devices.
    • 1.3 Malicious Workspace/Environment [HR]
      • 1.3.1 Social Engineering [HR]
        • Attack Vector: An attacker tricks a user into importing a malicious workspace or environment file containing crafted requests or scripts.
        • Details:
          • Attacker uses social engineering techniques (e.g., phishing emails, deceptive messages) to persuade the user.
          • The malicious workspace/environment might contain requests that exfiltrate data when run.
          • It could also contain scripts that execute malicious code within Insomnia's context.
      • 1.3.2 Phishing for Insomnia Credentials [HR]
        • Attack Vector: If Insomnia uses cloud sync, an attacker phishes for the user's cloud sync credentials.
        • Details:
          • Attacker creates a fake login page mimicking the cloud sync service.
          • Phishing emails or messages are used to lure the user to the fake page.
          • Once the user enters their credentials, the attacker gains access to their synced data.

Attack Tree Path: 2. Intercept/Modify Insomnia Network Traffic

  • This path is removed in the reduced tree, because the only high risk path (2.1) is conditional (if enabled).

Attack Tree Path: 3. Exploit Insomnia Plugin Vulnerabilities [CN]

  • Description: This is a critical node because Insomnia plugins can extend functionality and have access to sensitive data. Malicious or vulnerable plugins are a significant attack vector.
  • High-Risk Paths:
    • 3.3 Malicious Plugin [CN] [HR]
      • Attack Vector: An attacker installs a malicious plugin (either from a compromised repository or through social engineering) that is specifically designed to compromise Insomnia.
      • Details:
        • The plugin could be disguised as a legitimate plugin.
        • It could be distributed through unofficial channels or by compromising an official plugin repository (supply chain attack).
        • The plugin has access to Insomnia's internal data and can interact with the user's system.
      • Specific Attack Types (all [HR]):
        • 3.3.1 Data Exfiltration: The plugin steals API keys, credentials, request/response data, and other sensitive information.
        • 3.3.2 Request Manipulation: The plugin modifies API requests before they are sent, injecting malicious data or altering the intended behavior.
        • 3.3.3 Code Injection: The plugin injects arbitrary code into Insomnia, potentially gaining full control over the application and the user's system.
