## 기본 정보
|
|
|
|
**WHOIS** 프로토콜은 특정 데이터베이스를 통해 **다양한 인터넷 자원의 등록자 또는 소유자에 대한 문의를 위한 표준 방법**으로 사용됩니다. 이러한 자원에는 도메인 이름, IP 주소 블록 및 자율 시스템 등이 포함됩니다. 이 외에도, 이 프로토콜은 더 넓은 범위의 정보에 접근하는 데 사용됩니다.
|
|
|
|
**기본 포트:** 43
|
|
```
|
|
PORT STATE SERVICE
|
|
43/tcp open whois?
|
|
```
|
|
## Enumerate
|
|
|
|
도메인에 대한 whois 서비스가 가진 모든 정보를 가져옵니다:
|
|
```bash
|
|
whois -h <HOST> -p <PORT> "domain.tld"
|
|
echo "domain.ltd" | nc -vn <HOST> <PORT>
|
|
```
|
|
Notice than sometimes when requesting for some information to a WHOIS service the database being used appears in the response:

|
|
|

|
|
|
|
또한, WHOIS 서비스는 항상 정보를 저장하고 추출하기 위해 **데이터베이스**를 사용해야 합니다. 따라서 사용자가 제공한 정보로 **데이터베이스**를 **쿼리**할 때 **SQLInjection**이 발생할 수 있습니다. 예를 들어 `whois -h 10.10.10.155 -p 43 "a') or 1=1#"`를 실행하면 **데이터베이스**에 저장된 **모든** **정보**를 **추출**할 수 있습니다.

The WHOIS protocol serves as a standard method for inquiring about the registrants or holders of various Internet resources through specific databases. These resources encompass domain names, blocks of IP addresses, and autonomous systems, among others. Beyond these, the protocol finds application in accessing a broader spectrum of information.
