electronegativity
A static analysis tool to identify security misconfigurations and anti-patterns in Electron applications.
What is electronegativity?
Electronegativity is a static analysis security tool specifically built for Electron applications. It scans source code, configuration files, and packaged archives to identify security misconfigurations and anti-patterns that could lead to vulnerabilities. The tool helps developers and auditors ensure their Electron apps follow security best practices by automating checks based on established guidelines.
Electron application developers and security auditors who need to identify and fix security weaknesses in desktop applications built with the Electron framework.
Developers choose Electronegativity because it provides targeted, automated security analysis for Electron's unique risk profile, integrates into development workflows, and is backed by extensive security research from Doyensec.
Overview
Electronegativity is a tool to identify misconfigurations and security anti-patterns in Electron applications.
Use Cases
Best For
- Auditing Electron applications for security misconfigurations before release
- Integrating automated security checks into CI/CD pipelines for Electron projects
- Identifying insecure patterns like disabled context isolation or dangerous Node.js integration
- Checking for breaking changes and new vulnerabilities during Electron version upgrades
- Educating developers about Electron security best practices through actionable findings
- Performing static analysis on packaged ASAR archives without decompiling
Not Ideal For
- Teams requiring actively maintained security tools with regular updates and bug fixes
- Projects needing comprehensive SAST beyond static analysis, such as dynamic testing or runtime monitoring
- Non-Electron applications, as the tool is specifically designed for the Electron framework
Pros & Cons
Pros
Identifies misconfigurations like disabled context isolation and weak CSPs by leveraging AST and DOM parsing, as outlined in the Electron Security Checklist.
Can be automated via GitHub Actions to provide continuous security feedback in development pipelines, demonstrated in the README with code scanning alerts.
Allows fine-tuning with CLI flags and inline `eng-disable` comments to include or exclude specific checks, offering flexibility for targeted audits.
Checks for breaking changes and vulnerabilities when upgrading Electron versions, aiding in secure migrations with the `-u` flag for version comparisons.
Cons
The project is no longer actively maintained, with the authors promoting ElectroNG as an improved alternative, meaning no future updates or security patches.
Despite automation, a good understanding of Electron security is needed to interpret findings, as acknowledged in the README that some issues require manual investigation.
Can encounter 'JavaScript heap out of memory' errors on large codebases, necessitating manual node memory adjustments like `--max-old-space-size=4096`, as noted in the usage section.
