4. JavaScript

JavaScript is a primary weapon for ethical hackers looking to exploit vulnerabilities in web applications.

As the backbone of interactive web pages, JavaScript allows attackers to manipulate client-side scripts, inject malicious code, and steal sensitive user data through techniques like Cross-Site Scripting (XSS).

Key Benefits:

● Understanding how browsers and web pages process JavaScript is key to identifying vulnerabilities like XSS and Cross-Site Request Forgery (CSRF).

● It can be used to execute exploits remotely on web servers or clients.

Applications:

● Creating browser-based exploits (e.g., XSS attacks).

● Manipulating web application security to bypass protections.

● Testing and exploiting web application firewalls.

In today’s internet-driven world, web security is crucial, and JavaScript is central to this. Understanding JavaScript allows hackers to break into the heart of web apps and their users.

5. SQL

SQL is the standard query language for interacting with databases. As a hacker, understanding SQL allows you to uncover hidden vulnerabilities in web apps and systems.

Many modern applications rely on SQL-based databases to store sensitive data. Hackers use SQL injection techniques to exploit poorly secured databases, allowing them to execute arbitrary commands.

Key Benefits:

● SQL injection remains one of the most common and devastating attack methods.

● SQL is essential for understanding database structure, which is crucial when attempting to exfiltrate sensitive data like user credentials, financial records, and more.

Applications:

● Extracting data from insecure databases.

● Identifying vulnerable SQL queries that can be exploited.
