# IronEye

IronEye is a Rust-based Active Directory enumeration and security assessment tool designed for use in internal network environments. It enables penetration testers, red teamers, and security researchers to interact with LDAP, Kerberos, and SMB services efficiently.

The tool supports password and Kerberos authentication, allowing for credentialed LDAP queries, Kerberos protocol attacks, password spraying, Shadow Credentials abuse, ACL manipulation, DNS management, and more.

## Install and Compile

### Prerequisites

**Linux (Debian/Ubuntu/Kali):**
```bash
sudo apt install pkg-config libssl-dev libkrb5-dev libclang-dev
```

**Linux (Fedora/RHEL):**
```bash
sudo dnf install pkg-config openssl-devel krb5-devel clang-devel
```

**macOS:**
```bash
brew install openssl pkg-config
```

**Windows:** No additional dependencies required — OpenSSL is vendored automatically.

### Build

```bash
cargo build --release
```

## Authentication / Connect

IronEye supports three authentication modes for LDAP connections.

**Password authentication:**
```
-u tywin.lannister -p powerkingftw135 -d SEVENKINGDOMS.LOCAL -i 10.2.10.10
```

**Kerberos authentication (FQDN):**

Requires krb5.conf configuration. A sample is provided. Use the `Generate KRB5 Conf` option from the main menu to create one interactively.
```
-u robb.stark -d NORTH.SEVENKINGDOMS.LOCAL -i WINTERFELL.NORTH.SEVENKINGDOMS.LOCAL -k -s
```

**Kerberos authentication (IP with DC hostname):**
```
-u robb.stark -d NORTH.SEVENKINGDOMS.LOCAL -i 10.2.10.10 -k -dc-host WINTERFELL.NORTH.SEVENKINGDOMS.LOCAL
```

**Connection arguments:**
```
-u <user> -p <password> -d <domain> -i <FQDN/IP> [-s (LDAPS)] [-t (timestamps)] [-k (Kerberos)] [-dc-host <hostname>]
```

---

## Actions Menu

The Actions menu provides write/modification operations against AD objects. These require appropriate permissions on the target.

| Add User | Create a new user account with optional random password |
| Delete Computer | Remove a computer object from AD |

| Enable Account | Re-enable a disabled user or computer account |
| Disable Account | Disable a user or computer account |

### Credential and Access

| Action | Description |
|--------|-------------|
| Set Password | Reset a user's password (admin reset or old-password change) |
| Set UAC Flags | Modify User Account Control flags (DONT_EXPIRE_PASSWORD, DONT_REQUIRE_PREAUTH, TRUSTED_FOR_DELEGATION, etc.) |

### Group and Membership

| Action | Description |

| Add User to Group | Add a user to a security group |
| Remove User from Group | Remove a user from group membership |

| Action | Description |
|--------|-------------|

---

## Shadow Credentials

The Shadow Credentials module manipulates the `msDS-KeyCredentialLink` attribute to enable PKINIT authentication without a CA-issued certificate. Requires write access to the target's `msDS-KeyCredentialLink` attribute.

| Operation | Description |
|-----------|-------------|
| List Key Credentials | Display existing shadow credentials (DeviceId, creation time, key usage, key source, KeyID) |
| Add Shadow Credential | Generate an RSA 2048 key pair, write the key credential to AD, and export a PFX certificate for PKINIT |
| Remove Shadow Credential | Remove a specific credential by DeviceId |
| Clear All Key Credentials | Wipe all key credentials from the target (requires CLEAR confirmation) |

**Adding a shadow credential:**
```
Target: darth.vader
Output PFX: shadow_creds.pfx
PFX Password: ironeye
```

The generated PFX can be used with tools like Certipy for PKINIT authentication:
```bash
certipy auth -pfx shadow_creds.pfx -password ironeye -domain galactic.empire -dc-ip 10.1.10.10
```

## DNS Management (ADIDNS)

AD-Integrated DNS management for record manipulation. Searches both `DomainDnsZones` and `ForestDnsZones` partitions.

| Add A Record | Create a new DNS A record |
| Modify A Record | Update an existing A record's IP address |
| Remove (Tombstone) Record | Soft-delete a DNS record (tombstone) |
| Delete Record (LDAP) | Hard-delete a DNS record via LDAP |

---

## ACL / DACL Management

Add or remove discretionary access control entries on AD objects. Available rights:

| Right | Description |
|-------|-------------|
