Analysis Steps:

  1. Check for Hardcoded Secrets: Inspect the app’s source code or configuration files (e.g., latest.yml) for hardcoded credentials, API keys, or sensitive data. Use tools like IDA Pro, Ghidra, or Binary Ninja to disassemble the app.

  2. SQLite Database Inspection:
    • Verify if data.db contains stored authentication tokens or credentials.
    • Check for insecure storage (e.g., plaintext passwords). Use SQLite Browser or command-line tools to query the database.
  3. Custom Protocol Handler (acmedesk://):
    • Test if clicking acmed://* triggers unintended behavior (e.g., opening files outside the app’s sandbox).
    • Check if the protocol handler allows arbitrary code execution or exposes internal processes.
  4. PowerShell Execution:
    • Use Process Monitor (Sysinternals) to detect if spawnpowershell.exe is launched with suspicious parameters.
    • Analyze the command execution (-ExecutionPolicy Bypass, -File) for potential privilege escalation or malicious script runs.
  5. Update Mechanism (latest.yml):
    • Inspect the update server’s response (e.g., via Wireshark or Burp Suite).
    • Check if latest.yml contains references to malicious payloads, outdated dependencies, or unsafe update channels.
  6. Backup File Analysis:
    • Examine update.ps1 and associated .zip files for obfuscated scripts or compressed malware.
    • Use PEview or Strings.exe to scan for suspicious code in update.ps1.
  7. Electron-Specific Risks:
    • Confirm if Node.js integration (nodeIntegration: true) is enabled in main.js, which could expose the full Node API to renderers.
    • Check for context isolation bypasses in webPreferences.

Key Observations:

  • The app stores data in SQLite (%APPDATA%\AcmeDesk\data.db) and uses a custom protocol (acmedesk://), which could be exploited if not properly sandboxed.
  • PowerShell execution via spawnpowershell.exe suggests potential privilege escalation or script-based attacks.
  • The update mechanism (latest.yml) might fetch malicious scripts if the server is compromised.

Recommendations:

  1. Isolate Execution: Restrict nodeIntegration and disable context isolation in the Electron app’s configuration.
  2. Secure Storage: Hash sensitive data (e.g., tokens) before storing in SQLite to prevent plaintext exposure.
  3. Custom Protocol Handling: Ensure acmedesk:// links only access predefined app directories and not arbitrary system paths.
  4. Update Server Validation: Verify the integrity of latest.yml using cryptographic hashes (e.g., SHA-256) and scan downloaded files with ClamWin or VirusTotal.
  5. Backup Encryption: Encrypt .zip backups to prevent tampering or extraction of malicious content.

Tools for Analysis:

  • Static Analysis: IDA Pro, Ghidra, Binary Ninja.
  • Dynamic Analysis: WinDbg, x64dbg for debugging; Process Monitor to track PowerShell spawns.
  • Network Traffic: Wireshark, Burp Suite for reverse-engineering update checks.
  • File Inspection: SQLite Browser, PEview, Strings.exe.

Next Steps:

  1. Run the app in a sandboxed environment (e.g., Windows Sandbox) to monitor behavior without affecting the host system.
  2. Analyze network requests to updates.acme.local for suspicious patterns or redirects.
  3. Check the app’s Node.js modules (package.json) for known vulnerabilities (e.g., CVE-2021-4034).
