Osnovne informacije

Protokol WHOIS služi kao standardna metoda za istraživanje o registrovanim ili vlasnicima raznih Internet resursa putem specifičnih baza podataka. Ovi resursi obuhvataju imena domena, blokove IP adresa i autonomne sisteme, između ostalog. Pored ovoga, protokol se koristi za pristup širem spektru informacija.

Podrazumevani port: 43

PORT   STATE  SERVICE
43/tcp open   whois?

Enumerate

Dobijte sve informacije koje usluga whois ima o domenu:

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:

Takođe, WHOIS servis uvek mora koristiti bazu podataka za skladištenje i ekstrakciju informacija. Dakle, moguća SQLInjection može biti prisutna kada upitujete bazu podataka za neke informacije koje je pružio korisnik. Na primer, koristeći: whois -h 10.10.10.155 -p 43 "a') or 1=1#" mogli biste izvući sve informacije sačuvane u bazi podataka.
