Mitigation Strategies Analysis for vercel/hyper

Mitigation Strategy: Strict Plugin Vetting and Management (Hyper-Specific Aspects)

  • Description:

    1. Source Verification: Before installing, check the plugin's GitHub repository (if available) linked from the Hyper store. Look for activity, stars/forks, and a clear description.
    2. Code Review (if possible): If you have JavaScript/Node.js skills, download the plugin's source before installation via hpm and examine it for suspicious patterns (network requests, file access, eval()).
    3. Permission Awareness: Be mindful of any permission requests during plugin installation (though Hyper's current permission model is limited).
    4. Regular Audits: Regularly review installed plugins via the .hyper.js file or hpm list. Remove unused or unmaintained plugins.
    5. Manual Updates (Optional): Disable automatic plugin updates in .hyper.js by commenting out or modifying the updateChannel setting. This allows manual vetting before updating.
    6. Backup Configuration: Regularly back up your .hyper.js file.

  • Threats Mitigated:

    • Arbitrary Code Execution (Severity: Critical): Malicious plugins can run arbitrary code.
    • Data Exfiltration (Severity: High): Plugins can steal sensitive data.
    • System Modification (Severity: High): Plugins can modify system settings.
    • Denial of Service (Severity: Medium): Poorly written plugins can cause resource issues.

  • Impact:

    • Arbitrary Code Execution: Risk significantly reduced.
    • Data Exfiltration: Risk significantly reduced.
    • System Modification: Risk significantly reduced.
    • Denial of Service: Risk moderately reduced.

  • Currently Implemented:

    • Hyper's plugin management via .hyper.js and hpm.
    • Warning for plugins outside the official store.
    • Plugin update checks (configurable).

  • Missing Implementation:

    • Plugin Sandboxing: No isolation; plugins run with Hyper's privileges.
    • Automated Code Analysis: No built-in vulnerability scanning.
    • Fine-Grained Permissions: Limited control over plugin permissions.
    • Reputation System: Basic star ratings only.

Mitigation Strategy: .hyper.js Configuration Hardening (Hyper-Specific Aspects)

  • Description:

    1. Version Control: Store your .hyper.js in a Git repository. Commit changes to track modifications and revert if needed.
    2. Regular Backups: Include your .hyper.js in your regular system backups.

  • Threats Mitigated:

    • Unauthorized Configuration Changes (Severity: High): Prevents attackers from modifying settings to install malicious plugins.
    • Malware Persistence (Severity: High): Makes it harder for malware to use Hyper for persistence.

  • Impact:

    • Unauthorized Configuration Changes: Risk significantly reduced.
    • Malware Persistence: Risk moderately reduced.

  • Currently Implemented:

    • Hyper uses .hyper.js for configuration (standard text file).

  • Missing Implementation:

    • Built-in FIM: No built-in file integrity monitoring.
    • Configuration Encryption: .hyper.js is stored in plain text.
    • Tamper-Proofing: No specific anti-tampering mechanisms.

Mitigation Strategy: Renderer Process Exploit Mitigation (Hyper Update Focus)

  • Description:

    1. Minimize Plugin Count: Fewer plugins reduce the attack surface exposed through Electron.
    2. Prompt Hyper Updates: Update Hyper immediately when a new version is released, especially if release notes mention Electron or Chromium updates. Use Hyper's built-in update mechanism.

  • Threats Mitigated:

    • Remote Code Execution (Severity: Critical): Exploits targeting Chromium renderer vulnerabilities.
    • Data Exfiltration (Severity: High): Exploits could access data within Hyper.

  • Impact:

    • Remote Code Execution: Risk moderately reduced.
    • Data Exfiltration: Risk moderately reduced.

  • Currently Implemented:

    • Hyper uses Electron (benefits from Chromium updates).
    • Hyper provides an update mechanism.

  • Missing Implementation:

    • Renderer Process Isolation: Ideally, each tab/window would be isolated.
    • Stricter CSP: A more restrictive Content Security Policy could be used.
    • Automatic Vulnerability Scanning: No built-in scanning for Electron vulnerabilities.

Mitigation Strategy: Resource Usage Monitoring (Using Hyper and OS tools)

  • Description:

    1. Regular Monitoring: Periodically check Hyper's resource usage using your operating system's built-in tools (Task Manager on Windows, Activity Monitor on macOS, top or htop on Linux).
    2. Identify Resource-Intensive Plugins: If you notice Hyper consuming excessive CPU or memory, investigate which plugins might be responsible. Try disabling plugins one by one to identify the culprit, using hpm or editing .hyper.js.
    3. Report Issues: If you find a plugin that consistently causes high resource usage, report the issue to the plugin's developer.

  • Threats Mitigated:

    • Denial of Service (Severity: Medium): Prevents Hyper from becoming unresponsive.

  • Impact:

    • Denial of Service: Risk moderately reduced.

  • Currently Implemented:

    • Operating systems provide resource monitoring tools.
    • Hyper provides plugin management to disable plugins.

  • Missing Implementation:

    • Built-in Resource Monitoring: Hyper has no built-in monitoring.
    • Plugin Resource Limits: No way to limit plugin resource usage.
