How to map IPC channels and preload bridges in an Electron app with Awesome Reverse Engineering

Use hexvero to scan an Electron archive for IPC channels and window settings.

Authorization notice. Awesome Reverse Engineering is dual-use. Only use it on software, sites and systems you own or have explicit permission to test.

Who it is forA security reviewer who needs to understand how a desktop Electron app talks between its renderer and main process.

The problemElectron apps hide their inter-process messaging in large JavaScript bundles that are hard to review by hand.

The outcomeA list of IPC channels, preload bridges, and window settings found in the archive.

What you need first

  • A computer where you can install analysis tools, or a browser for web-based tools
  • A target to study, such as a sample binary you are authorized to analyze or a course lab
  • For malware or sandbox work: an isolated, disposable virtual machine and your organization's handling procedures
  • For the Electron triage tool: Node.js 22.12 or later, as the README states

Steps

  1. Read the hexvero entry in the File identification and triage section at https://github.com/maximilianfeix/hexvero.
  2. Install Node.js 22.12 or later, as the README requires.
  3. Install hexvero by following its own repository instructions.
  4. Point the CLI at the Electron archive you are reviewing.
  5. Check the output against the JavaScript code, since the README warns that pattern-based analysis can miss indirect code.

Prompt for your agent

Using the morluto/awesome-reverse-engineering list, summarize what hexvero reports for <electron-archive> and list the IPC channels and preload bridges it finds. Expected output: a table of channels with their source files. Verify that the report notes the limitation about indirect code.

Caveat. The README says pattern-based JavaScript analysis can miss indirect code, so results are a starting point, not a complete map.
