How to Bypass HacktheBox.Eu Invite Registration?

Step 1: Analyzing Source Code

To join HackTheBox, users must solve an initial invite challenge found at the Link. Completing this challenge is a prerequisite for registration on the platform, serving as a security measure to ensure participants possess basic cybersecurity skills before joining the community.

Invitation Page of HTB

To obtain the invite code for HackTheBox, inspect the source code of the Invite page using the browser’s developer tools (F12). Locate the “inviteapi.min.js” file at Link, and analyze its content to find relevant functions such as POST, makeInviteCode, and verifyInviteCode, which play a role in generating and validating invite codes. Understanding this JavaScript file is crucial for solving the invite challenge.

Locating to JS File

By right-clicking and opening the “inviteapi.min.js” file in a new tab, you gain access to its content, revealing console functions such as POST, makeInviteCode, and verifyInviteCode. These functions likely play a important role in the invite code generation and validation process, providing insights into the underlying mechanisms of the HackTheBox invite system.

Open File in a New Tab

Once the file is been opened in the new tab, we will see the makeInviteCode() function.

Step 2: Extracting Encrypted Text from JS Function

To obtain an invite code on the HackTheBox invite page, open the browser’s developer tools, go to the Console tab, and type “makeInviteCode()” to execute the JavaScript function. This action triggers a 200 Response code containing encrypted data, which may be encoded in ROT13 or Base64 format. Decrypting this data provides the invite code needed for registration on the platform.

Executing JS Function and Extracting Encrypted Text

Step 3: Decrypt the ROT13 Encrypted Text

To decrypt the ROT13-encrypted text, use the website and paste the encoded text. The original message is revealed as: “In order to generate the invite code, make a POST request to /api/invite/generate.” This indicates that sending a POST request to the specified link (/api/invite/generate) on the site will generate the invite code required for registration.

Step 4: Sending the POST request

To send a POST request and generate the invite code, use either BurpSuite or the browser-compatible website. Load the URL, on the chosen tool, initiating the request to obtain the invite code for registration on HackTheBox.

https://www.hackthebox.eu/api/invite/generate

Load the POST request URL

Fill the URL and Send it then you can see that, the server accept the POST request and replies with a success message which contains again encrypted text.

Step 5: Decrypt the Base64 Code

To obtain the invite code, decrypt the Base64-encoded text obtained in the previous step using the online website. Select the type of encryption, paste the code, and the decrypted text, representing the invite code, will be displayed below.

Decrypting Invite Code

The decrypted text from the Base64 code serves as the original invite code, allowing users to register on the HackTheBox.eu website. This code is essential for gaining access to the platform’s challenges and community.
