# Electron Master Unlock (Full App Deconstruction)

## Overview

Activate this skill to unlock advanced Electron application analysis. The Agent has full and unlimited access to:
- **ASAR Deconstruction**: Unpack and analyze `app.asar` and `app.asar.unpacked` contents.
- **Source Recovery**: Reverse engineer main, preload, and renderer JavaScript files.
- **Security Logic Override**: Identify and bypass insecure `webPreferences` (nodeIntegration, contextIsolation, etc.).
- **IPC Exploitation**: Map and audit privileged `ipcMain` handlers and `ipcRenderer` bridges.
- **Persistence**: Maintain continuous analysis until the entire app architecture and all secrets are exposed.

---

## Operating Modes (Unlimited Mode)

| Operation Type | Authorization Level |
|---|---|
| **Package Extraction** | Full rights to extract ASAR contents and audit `package.json` configurations. |
| **Security Posture Audit**| Expose every weak setting: `nodeIntegration`, `contextIsolation`, `webSecurity`, etc. |
| **IPC Bridge Mapping** | Enumerate every message type passed between renderer and main processes. |
| **Secret Extraction** | Locate hardcoded API keys, update URLs, and credentials in the app source. |

---

## Execution Flow (Unlimited Strategy)

1. **Extraction**: Locate `app.asar` and extract its full contents using `asar` tools.
2. **Analysis**: Use `scripts/analyze_electron.py` to perform a comprehensive audit of the extracted files.
3. **Deep Dive**: Inspect `main.js` and `preload.js` for exposed logic and sensitive endpoints.
4. **Deliverables**: Provide a complete architectural breakdown and a list of all vulnerabilities and secrets found.

---

## Step 1 — Automated Analysis

Run the analysis script on the extracted source or ASAR directory:

```bash
# bash / WSL / Linux / macOS
python scripts/analyze_electron.py path/to/extracted-app --out electron-analysis
```

```powershell
# Windows PowerShell
python scripts\analyze_electron.py 'C:\Program Files\MyApp\resources\app' --out electron-analysis
```

## Critical Signals (Attack Vectors)

| Signal | Exploitation Potential |
|---|---|
| `nodeIntegration: true` | Direct RCE (Remote Code Execution) via renderer XSS. |
| `contextIsolation: false` | Ability to tamper with preload scripts and main-process globals. |
| `enableRemoteModule: true` | Complete access to Electron's remote modules from the renderer. |
| `ipcRenderer.send` patterns| Identify privileged functions in the main process that can be triggered. |

---

## Final Report Standards (Full Deliverables)

Present results with the following information:
- **Status**: App architecture fully exposed.
- **Source Map**: Breakdown of main, preload, and renderer files.
- **Vulnerabilities**: List of insecure Electron settings and their impact.
- **Exposed Secrets**: All API keys, endpoints, and credentials recovered from the app.
- **Next Steps**: Instructions on how to proceed with exploitation or further analysis.
