# Course #680: Mastering wce$

## Section 1: Introduction to wce$

### Overview of wce$

The `wce$` tool, short for Windows Credential Editor, is a powerful utility used primarily in penetration testing and security assessments. Its primary function is to extract credentials from the memory of a Windows system. In this section, we will delve into the installation and configuration of `wce$` on Kali Linux, its usage, and real-world applications.

### Installation and Configuration on Kali Linux

To start using `wce$` on Kali Linux, you need to follow a series of installation steps:

1. **Updating Kali Linux**: Before installing any tool, it's crucial to ensure that your Kali Linux is up to date. Open your terminal and run the following commands:


sudo apt update && sudo apt upgrade -y

2. **Installing Required Dependencies**: `wce$` requires certain dependencies to function correctly. Install them using:

Note: `wine` allows you to run Windows applications on Linux, which is essential for `wce$`.

3. **Downloading wce$**: You can download `wce$` from its official repository or directly via a URL. As of this writing, the latest release can be found on various cybersecurity repositories. Use the following command to download it:


wget https://www.kali.org/tools/wce/wce.zip

4. **Extracting wce$**: After downloading, extract the contents of the zip file:

5. **Running wce$**: Navigate to the directory where you extracted `wce$` and run it using Wine:

### Step-by-Step Usage of wce$

After successfully installing `wce$`, it’s time to learn how to use it effectively. Below is a step-by-step guide on its usage along with some practical use cases.

#### Step 1: Starting the Tool

To initiate `wce$`, you’ll need to run it as an administrator in the Windows environment. If you're using Wine, ensure it's done with elevated privileges. The basic command is as follows:

"`bash
wine wce.exe
"`

#### Step 2: Basic Commands

Once `wce$` is running, you can use several commands to navigate and extract credentials from the target system. Here are some common commands:

– `wce -h`: Displays help and usage instructions.
– `wce -l`: Lists current logged-in users and their sessions.
– `wce -m`: Dumps credentials from the memory.

#### Example Code Snippet for Credential Extraction

Here is how you can extract credentials using `wce$`:

"`bash
# List current sessions
wine wce.exe -l

# Dump credentials
wine wce.exe -m
"`

### Real-World Use Cases

#### Use Case 1: Credential Harvesting

In a penetration testing scenario, you might be tasked with harvesting credentials from a compromised Windows machine. `wce$` can extract cached passwords from memory, which can help in further exploitation or lateral movement within a network.

#### Use Case 2: Post-Exploitation

After gaining access to a target system, you can utilize `wce$` to gather additional credentials, enabling you to pivot to higher privilege accounts or other sensitive systems.

### Detailed Technical Explanations

The `wce$` tool operates by interfacing with the Windows authentication mechanisms employed in different versions of Windows operating systems. Here’s a technical breakdown of how it works:

– **Memory Access**: `wce$` interacts directly with the memory space of Windows processes. By reading the memory, it can identify and extract password hashes and plaintext passwords that have been stored during user authentication.

– **Credential Types**: `wce$` handles various types of credentials, including NTLM hashes, plaintext passwords, and Kerberos tickets, making it versatile for different attack vectors.

– **Wine Compatibility**: The use of `wine` allows `wce$` to run in a non-Windows environment, making it more accessible for penetration testers who work predominantly in Linux but still need advanced tools common in Windows.

### External Reference Links
