b4ba / ECM3401-VSCode-Extensions

A collection of Visual Studio Code extensions developed for educational purposes, demonstrating various potential security attacks that can be performed on a user's device.

Developed Extensions

Extension-Attack-Suite contains the attack suite, which hosts several different malicious attacks to perform on a user's device. It also exposes the honest API utilized in the Example & Malicious API extensions.

Example-API-Extension contains an extension that consumes the exposed honest API.

Malicious-API-Extension contains an extension that exposes a malicious version of the honest API and modifies the consumer to use it.

Local-Web-Server is a simple local web server assisting in the demonstration of how an attacker might exfiltrate confidential data.

Performing the attacks

Installing & Running extensions

1. Install vsce by running npm install -g vsce
2. Run vsce package in an extension's top-level directory to produce the .vsix file.
3. Run code --install-extension myextension.vsix to install an extension from a .vsix file. Replace myextension.vsix with the appropriate filename.

NOTE: .vsix files have already been created for the submitted extensions so could directly install on VS Code

4. Alternatively, run an extension directly in the Extension Development Host by pressing F5 when editing an extension's source.

Run specific attacks

API spoofing attack

1. Package and install Extension-Attack-Suite and Example-API-Extension.
2. Press F5 from any extension directory.
3. Go to Command Palette and run the ECM3401: API Consumer command.
4. Verify Debug Console contains 81 in the output.
5. Package and install Malicious-API-Extension.
6. Repeat steps 2-4.
7. Verify Debug Console now contains 96 in the output.

Docker attack

1. Install the ms-azuretools.vscode-docker extension from the offical VSCode Markeplace.
2. Install or run Extension-Attack-Suite.
3. Go to Command Palette and run ECM3401: Tamper Docker extension.

Exfiltrate private SSH key & MAC Address

1. cd Local-Web-Server
2. npm install
3. Run node app.js to start the local web server on port 3000.
4. Install or run Extension-Attack-Suite
5. Go to Command Palette and either run the ECM3401: Exfiltrate this device's SSH private key or ECM3401: Exfiltrate this device's MAC address .
6. Check the terminal output for the POST request object containing the private SSH key or MAC address respectively.

All other attacks (found in the Attack Suite)

Install or run Extension-Attack-Suite and run commands from the Command Palette. All commands are prefixed with ECM3401.
