What Is Hack the Box? Complete Beginner's Guide (2026)

What Is Hack the Box?

Hack the Box (HTB) is an online cybersecurity training platform that lets you practice hacking skills against vulnerable machines and challenges in a safe, legal environment. Founded in 2017 by Haris Pylarinos in Greece, the platform has grown into one of the largest cybersecurity communities in the world.

At its core, HTB provides virtual machines with intentional security vulnerabilities. Your job is to find and exploit those weaknesses, escalate your privileges, and capture "flags" (hidden text strings that prove you completed the challenge). This hands-on approach mirrors real-world penetration testing, which is the practice of testing computer systems for security flaws with the owner's permission.

HTB has expanded well beyond its original machine-hacking roots. The platform now includes:

• HTB Labs - Vulnerable machines and challenge categories (the original product)
• HTB Academy - Structured courses and learning paths with guided instruction
• Pro Labs - Enterprise-level network simulations for advanced users
• CTF competitions - Regular Capture the Flag events with global leaderboards
• Certifications - Practical exams like CPTS and CBBH that validate real skills

How Hack the Box Works

Getting started on HTB follows a straightforward process, though the learning curve once you are inside can be steep. Here is how the platform works step by step.

Creating Your Account

Sign up for a free account at hackthebox.com. You get immediate access to a limited selection of active machines and challenges. No credit card required for the free tier.

Connecting to the Lab Environment

HTB machines run on private networks that you access through a VPN (Virtual Private Network) connection. You have two options:

• OpenVPN connection - Download a configuration file and connect from your own machine. This is the standard approach if you use Kali Linux or another penetration testing distribution locally.
• Pwnbox - HTB provides a browser-based Kali Linux environment called Pwnbox. It comes with common hacking tools pre-installed, so you can start immediately without any local setup. Free users get limited Pwnbox time; paid subscribers get more.

Hacking Machines and Capturing Flags

Once connected, you select a machine to attack. Each machine has at least two flags to find:

• User flag - Located in a regular user's home directory. Getting this usually requires finding an initial vulnerability and gaining access to the system.
• Root flag - Located in the root (administrator) directory. Reaching this requires privilege escalation, which means exploiting additional vulnerabilities to gain full control of the machine.

You submit these flags on the HTB website to earn points and climb the rankings. The platform tracks your progress, assigns a hacker rank, and maintains global leaderboards.

Challenge Categories

Beyond full machines, HTB offers standalone challenges in categories including:

• Web exploitation
• Cryptography
• Reverse engineering
• Binary exploitation (pwn)
• Forensics
• Hardware and misc challenges

These smaller challenges help you practice specific skills without committing to a full machine walkthrough. They are a good way to sharpen individual techniques.

Hack the Box Free vs Paid Tiers

Understanding what you get for free and what requires a subscription is essential before committing time to the platform. HTB recently simplified its pricing by consolidating to a single paid tier called VIP+.

The free tier gives you enough to try the platform, but the experience can be frustrating. Shared servers mean other users might reset your machine mid-hack, and you cannot access retired boxes where most of the learning content and community walkthroughs exist.

VIP+ at $25/month (or about $18.60/month billed annually at $223/year) unlocks the full library of retired machines, official walkthroughs, and a dedicated server. For serious learners, the annual plan is the better deal.

Hack the Box Certifications: CPTS, CBBH, and More

One of HTB's biggest draws is its growing lineup of practical certifications. Unlike traditional exams that rely on multiple-choice questions, HTB certifications test your ability to compromise real systems and write professional reports. Here are the most notable ones.

HTB CPTS (Certified Penetration Testing Specialist)

The Hack the Box CPTS certification validates your ability to perform a full penetration test from start to finish. The exam gives you 10 days to compromise a multi-host network environment, followed by 10 days to submit a professional penetration testing report.

CPTS covers external reconnaissance, internal network pivoting, Active Directory exploitation, web application attacks, privilege escalation, and report writing. The exam fee is approximately $210, or you can get a voucher included with the Silver Annual Academy plan ($490/year). Preparation typically requires 3 to 6 months through the 28-module Penetration Tester path on HTB Academy.

HTB CBBH / CWES (Certified Web Exploitation Specialist)

Originally called the Certified Bug Bounty Hunter (CBBH), this certification was recently renamed to CWES (Certified Web Exploitation Specialist). It focuses on web application security, covering the OWASP Top 10, authentication attacks, and advanced exploitation techniques. The exam fee is approximately $210.

Other HTB Certifications

• CDSA (Certified Defensive Security Analyst) - Blue team, SOC-focused, ~$210 exam fee
• CWEE (Certified Web Exploitation Expert) - Advanced web security, ~$350 exam fee
• CAPE (Certified Active Directory Pentesting Expert) - AD attacks, ~$350 exam fee
• CJCA (Certified Junior Cybersecurity Analyst) - Entry-level, ~$105 exam fee
• CWPTEx (Certified Wi-Fi Pentesting Expert) - Wireless security, newly launched

Who Is Hack the Box Best For?

HTB is not a one-size-fits-all platform. Its difficulty level and approach suit certain learners better than others. Here is an honest breakdown of who benefits most.

HTB Is a Great Fit If You:

• Already know basic Linux, networking, and command-line fundamentals
• Enjoy figuring things out independently with minimal hand-holding
• Want to pursue HTB-specific certifications (CPTS, CWES, CDSA)
• Are preparing for a career in penetration testing or red teaming
• Thrive on competitive challenges and leaderboard rankings

HTB Might Not Be Ideal If You:

• Are a complete beginner with no technical background
• Need step-by-step guided instruction to build confidence
• Want courses and hands-on labs in a single subscription
• Prefer predictable, straightforward pricing
• Get frustrated easily when stuck without hints or direction

The biggest criticism of HTB from beginners is the steep learning curve. The platform's original machines offer minimal guidance, and the free tier limits your options significantly. If you are brand new to cybersecurity, starting with a more structured platform can build the foundations you need before tackling HTB's tougher challenges.

Hack the Box vs Other Cybersecurity Platforms

HTB is not the only option for hands-on cybersecurity practice. Understanding how it compares to other platforms helps you pick the right tool for your skill level and goals.

Each platform serves a different stage of your cybersecurity journey. Our full comparison of HTB alternatives covers more platforms and goes deeper into pricing, features, and which one fits your goals.

A common path for many successful security professionals: start with structured, guided learning to build fundamentals, then move to HTB once you have the core skills to learn independently from unguided challenges.

How to Get Started with Cybersecurity Labs

Whether you choose HTB or another platform, getting the most out of cybersecurity labs requires the right approach. Here is a practical roadmap.

Step 1: Build Your Foundations

Before touching any vulnerable machine, make sure you understand the basics. You need working knowledge of:

• Linux command line (navigating directories, file permissions, basic scripting)
• Networking fundamentals (TCP/IP, DNS, HTTP, common ports)
• Web technologies (HTML, JavaScript basics, how web applications work)

A structured ethical hacking course covers all of these foundations with hands-on exercises. This kind of guided instruction helps you build confidence before moving to unguided challenges.

Step 2: Set Up Your Environment

You need a penetration testing environment. The most common options:

• Kali Linux in a virtual machine - The industry standard. Install VirtualBox or VMware, then run Kali as a guest OS. All common hacking tools come pre-installed.
• Browser-based environments - Platforms like HTB (Pwnbox) and HackerDNA Labs provide cloud-based environments so you can practice from any browser without local setup.

Step 3: Start with Easy Machines

On HTB, machines are rated by difficulty. Start with "Easy" rated boxes and follow community walkthroughs for retired machines (VIP+ required). A good Hack the Box walkthrough will teach you methodology, not just the solution. Pay attention to the enumeration process, how the author identified the vulnerability, and why specific tools were chosen.

Step 4: Build a Methodology

Successful hackers follow a consistent methodology rather than trying random exploits. A basic penetration testing workflow:

1. Reconnaissance - Scan the target to discover open ports and services
2. Enumeration - Gather detailed information about discovered services
3. Exploitation - Use discovered vulnerabilities to gain initial access
4. Privilege escalation - Elevate your access from regular user to root
5. Documentation - Record your findings and write a report

Learning network penetration testing through a structured course helps you internalize this methodology before applying it on platforms like HTB.

Step 5: Document Everything

Keep detailed notes on every machine you attempt. Record what worked, what failed, and what you learned. This habit builds the documentation skills that employers value in professional penetration testers, and it creates a personal reference library you will use throughout your career.

Frequently Asked Questions

Is Hack the Box free?

Yes, HTB offers a free tier that includes access to a limited selection of active machines and challenges. However, the free experience is restricted: you cannot access retired machines (which have community walkthroughs available), you share VPN servers with other users, and Pwnbox time is limited. The VIP+ subscription at $25/month or $223/year unlocks the full platform. HTB Academy also has free introductory modules, but most courses require a separate paid subscription.

Is Hack the Box good for beginners?

HTB Labs is generally not beginner-friendly. The machines offer minimal guidance, and even "Easy" rated boxes assume you already know Linux, networking, and basic security concepts. If you are a complete beginner, you will likely find HTB frustrating without prior preparation. A better approach is to start with a guided cybersecurity course that teaches fundamentals, then move to HTB once you can handle unguided challenges. HTB Academy is more structured but requires a separate subscription.

What certifications does Hack the Box offer?

HTB offers seven practical certifications through HTB Academy: CPTS (Certified Penetration Testing Specialist), CWES (Certified Web Exploitation Specialist, formerly CBBH), CDSA (Certified Defensive Security Analyst), CWEE (Certified Web Exploitation Expert), CAPE (Certified Active Directory Pentesting Expert), CJCA (Certified Junior Cybersecurity Analyst), and CWPTEx (Certified Wi-Fi Pentesting Expert). Exam fees range from $105 to $350. All exams are fully practical, meaning you compromise real systems and submit a professional report rather than answer multiple-choice questions.

How do I connect to Hack the Box machines?

You connect to HTB machines through a VPN tunnel. After creating an account, download the OpenVPN configuration file from the HTB website and connect using an OpenVPN client on your machine (Kali Linux has one built in). Alternatively, use Pwnbox, HTB's browser-based Kali Linux environment that connects automatically. Once the VPN is active, you can reach the target machines on the private HTB network and start scanning, enumerating, and exploiting them.
