## Basic Information
|
|
|
|
The **Ident Protocol** is used over the **Internet** to associate a **TCP connection** with a specific user. Originally designed to aid in **network management** and **security**, it operates by allowing a server to query a client on port 113 to request information about the user of a particular TCP connection.
|
|
|
|
However, due to modern privacy concerns and the potential for misuse, its usage has decreased as it can inadvertently reveal user information to unauthorized parties. Enhanced security measures, such as encrypted connections and strict access controls, are recommended to mitigate these risks.
|
|
|
|
**Default port:** 113
|
|
|
|
```
|
|
PORT STATE SERVICE
|
|
113/tcp open ident
|
|
```
|
|
|
|
## **Enumeration**
|
|
|
|
### **Manual - Get user/Identify the service**
|
|
|
|
If a machine is running the service ident and samba (445) and you are connected to samba using the port 43218. You can get which user is running the samba service by doing:
|
|
|
|
 (1) (1).png>)
|
|
|
|
If you just press enter when you conenct to the service:

|
|
|
 (1) (1).png>)
|
|
|
|
Other errors:
|
|

|

|
|
|
|
### Nmap
|
|
|
|
By default (`-sC``) nmap will identify every user of every running port:
|
|
|
|
```
|
|
PORT STATE SERVICE VERSION
|
|
22/tcp open ssh OpenSSH 4.3p2 Debian 9 (protocol 2.0)
|
|
|_auth-owners: root
|
|
| ssh-hostkey:
|
|
| 1024 88:23:98:0d:9d:8a:20:59:35:b8:14:12:14:d5:d0:44 (DSA)
|
|
|_ 2048 6b:5d:04:71:76:78:56:96:56:92:a8:02:30:73:ee:fa (RSA)
|
|
113/tcp open ident
|
|
|_auth-owners: identd
|
|
139/tcp open netbios-ssn Samba smbd 3.X - 4.X (workgroup: LOCAL)
|
|
|_auth-owners: root
|
|
445/tcp open netbios-ssn Samba smbd 3.0.24 (workgroup: LOCAL)
|
|
|_auth-owners: root
|
|
```
|
|
|
|
### Ident-user-enum
|
|
|
|
[**Ident-user-enum**](https://github.com/pentestmonkey/ident-user-enum) is a simple PERL script to query the ident service (113/TCP) in order to determine the owner of the process listening on each TCP port of a target system. The list of usernames gathered can be used for password guessing attacks on other network services. It can be installed with `apt install ident-user-enum`.
|
|
|
|
```
|
|
root@kali:/opt/local/recon/192.168.1.100# ident-user-enum 192.168.1.100 22 113 139 445
|
|
ident-user-enum v1.0 ( http://pentestmonkey.net/tools/ident-user-enum )

|
|

|
|

|
|
