**Onmiddellik beskikbare opstelling vir kwesbaarheidsassessering & penetrasietoetsing**. Voer 'n volledige pentest vanaf enige plek uit met 20+ gereedskap & funksies wat van rekognisie tot verslagdoening strek. Ons vervang nie pentesters nie - ons ontwikkel pasgemaakte gereedskap, opsporing & eksploitasiemodules om hulle weer 'n bietjie tyd te gee om dieper te delf, shells te pop en pret te hê.

## **Basiese Inligting**

Telnet is 'n netwerkprotokol wat gebruikers 'n ONveilige manier bied om toegang tot 'n rekenaar oor 'n netwerk te verkry.

**Standaard poort:** 23
```
23/tcp open  telnet
```
## **Enumerasie**

### **Banner Grabbing**
```bash
nc -vn <IP> 23
```
Alle interessante enumerasie kan uitgevoer word deur **nmap**:
```bash
nmap -n -sV -Pn --script "*telnet* and safe" -p 23 <IP>
```
Die skrip `telnet-ntlm-info.nse` sal NTLM-inligting verkry (Windows weergawes).

Van die [telnet RFC](https://datatracker.ietf.org/doc/html/rfc854): In die TELNET-protokol is daar verskeie "**opsies**" wat goedgekeur sal word en gebruik kan word met die "**DO, DON'T, WILL, WON'T**" struktuur om 'n gebruiker en bediener in staat te stel om saam te stem om 'n meer uitgebreide (of dalk net ander) stel konvensies vir hul TELNET-verbinding te gebruik. Sulke opsies kan insluit die verandering van die karakterstel, die echo-modus, ens.

**Ek weet dit is moontlik om hierdie opsies te tel, maar ek weet nie hoe nie, so laat weet my as jy weet hoe.**

### [Brute force](../generic-methodologies-and-resources/brute-force.md#telnet)
