## Pentest Course with Code-OSS

### Section 1: Introduction to Code-OSS

Welcome to the first section of our advanced pentesting course utilizing Code-OSS, an open-source version of Visual Studio Code tailored for security professionals and ethical hackers. This section will walk you through the installation and configuration of Code-OSS on Kali Linux, provide step-by-step usage instructions, real-world use cases, and detailed technical explanations.

#### Installation and Configuration on Kali Linux

Before we begin, ensure you have the latest version of Kali Linux installed on your machine. Code-OSS is available via the Kali repositories, making installation straightforward.

##### Step 1: Update Your System

Open a terminal and run the following commands to ensure your system is up to date:

"`bash
sudo apt update && sudo apt upgrade -y
"`

##### Step 2: Install Code-OSS

To install Code-OSS, use the following command:

"`bash
sudo apt install –assume-yes code-oss
"`

This command fetches Code-OSS from the Kali repositories and installs it along with all required dependencies.

##### Step 3: Launch Code-OSS

To start Code-OSS, simply type the following command in your terminal:

"`bash
code-oss
"`

Alternatively, you can find it in your applications menu under "Programming."

##### Step 4: Initial Configuration

On your first launch, you might want to configure a few settings to optimize your environment:

1. **Change the Theme:** Go to `File > Preferences > Color Theme` and choose a theme that is easy on the eyes during long pentesting sessions.
2. **Install Extensions:** Navigate to the Extensions view (Ctrl+Shift+X) and search for essential extensions like **Python**, **C/C++**, or any relevant tools that enhance your pentesting workflow.

### Step-by-Step Usage and Real-World Use Cases

Now that you have Code-OSS installed and configured, let’s delve into how you can effectively utilize it for pentesting.

#### Use Case 1: Vulnerability Scanning

Vulnerability scanning is a critical part of pentesting. In this case, we will show how to utilize Code-OSS to analyze and scan for vulnerabilities in a web application using a Python script.

**Step 1: Create a New Python File**

1. Open Code-OSS and create a new file.
2. Save it with a `.py` extension, for example, `vuln_scanner.py`.

**Step 2: Write the Code**

Here’s a simple example of a vulnerability scanner that checks for common web application vulnerabilities:

"`python
import requests

# List of common vulnerabilities
vulns = [
"' OR '1'='1",
"' OR '1'='1' –",
"' OR 'x'='x",
]

url = input("Enter the target URL: ")

for vuln in vulns:
full_url = f"{url}?id={vuln}"
response = requests.get(full_url)

if "SQL syntax" in response.text:
print(f"Possible SQL injection vulnerability found at: {full_url}")
"`

**Step 3: Run the Script**

To execute the script, open a terminal in Code-OSS (using the integrated terminal) and run:

"`bash
python3 vuln_scanner.py
"`

Enter the target URL when prompted, and the script will check for potential SQL injection vulnerabilities.

#### Use Case 2: Code Analysis

Another crucial aspect of pentesting is code analysis, specifically reviewing third-party libraries for vulnerabilities.

**Step 1: Clone a Repository**

To analyze a repository, you can use Git to clone it:

"`bash
git clone https://github.com/example/repo.git
cd repo
"`

**Step 2: Open in Code-OSS**

Open the cloned repository in Code-OSS:

"`bash
code-oss .
"`

**Step 3: Use Linters and Static Analysis Tools**

You can set up linters and static analysis tools directly in Code-OSS. Install a relevant extension, such as the ESLint for JavaScript projects or Pylint for Python projects, to automatically analyze the code for potential vulnerabilities.

### Detailed Technical Explanations

#### Understanding the Risks

1. **SQL Injection:** SQL Injection occurs when an attacker can manipulate a web application's database query by submitting malicious input. The above script demonstrates a simple way to probe for this vulnerability.

2. **Cross-Site Scripting (XSS):** XSS vulnerabilities allow attackers to inject malicious scripts into content that other users will view. Always sanitize user inputs.

3. **Insecure Deserialization:** This occurs when an application deserializes data from an untrusted source, allowing an attacker to manipulate objects or commands.

### Conclusion

Code-OSS is a robust tool that empowers ethical hackers and penetration testers to perform effective analyses and assessments. With its extensive feature set and adaptability through extensions, it can be tailored to suit various pentesting requirements.

In this section, you learned how to install and configure Code-OSS on Kali Linux, along with practical, real-world use cases that highlight its capabilities in vulnerability scanning and code analysis.
