iRealm 🔐

iRealm is a Kerberos-focused automation tool designed to prepare your Kali system for Active Directory interaction. It streamlines the initial setup by handling /etc/hosts, time synchronization, and Kerberos configuration — all in one smooth execution.

Whether you're attacking a domain in Hack The Box, TryHackMe, or conducting a real red team engagement, iRealm gets you domain-ready in seconds.

🛠️ Installation

Prerequisites

In the case of installing krb5, if it asks you to enter a REALM, leave it empty and accept

sudo apt install faketime rdate krb5-config krb5-user -y

Installing the tool

wget https://raw.githubusercontent.com/Gzzcoo/iRealm/main/iRealm
chmod +x iRealm
sudo mv iRealm /usr/local/bin/iRealm

⚙️ Usage

Interactive mode

iRealm

You will be prompted to enter:

• Domain Controller IP
• Domain name (e.g., gzzcoo.htb)
• Hostname (e.g., dc01)

Silent mode (no prompts)

iRealm --force <IP> <DOMAIN> <HOSTNAME>

Example:

iRealm --force 10.10.10.10 gzzcoo.htb dc01

🚀 Features

• Adds the Domain Controller and domain name to /etc/hosts.
• Synchronizes your system time with the Domain Controller to prevent Kerberos clock skew issues.
• Replaces /etc/krb5.conf with a valid Kerberos configuration.
• Creates an automatic backup of your previous Kerberos config.
• Supports both interactive and non-interactive modes.

📌 Why use iRealm?

Working in Active Directory environments often requires Kerberos to be properly configured — and misconfigurations can cause tools like GetNPUsers, GetUserSPNs, or psexec.py to fail silently.

iRealm ensures your box is ready for action with:

• Correct DNS resolution to the DC
• Accurate system time
• Valid Kerberos realm configuration
