2)Resource Records and the Zone file -A Zone file is basically a text file present on the server hosting the domain that contains entries for different resource records. MX Records-This basically tells us which server is responsible for receiving mails sent to that domain name.
I will take this moment to introduce DIG which is a handy little tool, we can also do the same queries using DIG.
WildCard – A wildcard entry is used to provide responses for subdomains that do not exist.
5)DNS Zone Transfer-We saw in the previous exercises that every domain has some authoritative name servers associated with it. To protect your nameservers from leaking valuable information, one must allow zone transfer to other nameservers of the same domain only. DNS protocol is a very critical component of the Internet as it resolves IP-address into hostnames and makes life a lot easier for us.
Prateek Gianchandani, a recent IIT graduate, has interests in the field of Penetration Testing, Web Application Security and Intrusion Detection. Indeed it is, it’s funny that even most of the hosting service providers do not recognize that, leaving their NS to allow zone transfer from any client !

This means that we are querying for the A records which will return us an IP-address in return for the domain we query. This basically means that our DNS server queried an external DNS server to fetch the IP-address. Each line is represented by a different record .In some cases these records may exceed one line and hence must be enclosed within a parantheses. The general way of writing a resource record is writing the domain name, record class, record type, and then some additional information.
I type in the domain name as the second command and get the corresponding IP-address for it.
Note that querying from your own dns server may not give you the accurate information every time. We will do this by traversing the entire DNS hierarchy from the root servers to the top level domain. Notice the dot (.) at the end, this is what makes this a fully qualified domain name (FQDN). However, if the nameservers are not properly configured they might leak out the whole DNS server database to any malicious hacker. I would like to hear real world stories on how improperly configured DNS servers brought down the whole network. We have been training Information Security and IT Professionals since 1998 with a diverse lineup of relevant training courses.

Two of the major ones are Application Performance Monitoring (formally known as AviCode) and network device discovery and monitoring. However some security vulnerabilities exist due to misconfigured DNS nameservers that can lead to information disclosure about the domain.
This process may take place through a local cache or through a zone file that is present on the server. It is now the responsibility of the DNS resolver in the user’s operating system to fetch the IP address. Each zone file must start with a Start of Authority (SOA) record containing an authoritative nameserver for the domain (for e.g.
Note that finding the nameservers can give us some information about the hosting provider of the domain.
We have a wordlist in which we contain the subdomain names we want to test the domain against.
Since one of the nameservers is not properly configured, it allows zone transfer and what we see is a dump of all the information (records,subdomains etc). Most of the DNS servers are properly configured and do not allow zone transfers to every client. Fierce is a very handy tool for DNS Analysis and it is something everyone should have in their armory.
Even if the servers are properly configured, they can be brute forced to leak information about their mail servers, IP addresses, etc. In the past 16 years, over 50,000 individuals have trusted InfoSec Institute for their professional development needs! This forms an important step of the Information Gathering stage during a Penetration test or Vulnerability assessment.
A zone file is a file on the server that contains entries for different Resource Records (RR).
It first checks it’s local cache to see if it can find a record for the queried domain name. Then we do a ping of all these subdomains, if these domains resolve to an IP-address different than the host IP-address, then we can very surely say that this subdomain actually exists. Usually a big organization will have more than one nameservers so that if one goes down for some time, the other one is ready to back it up and handle the requests.
Fierce will first check if Zone transfers are allowed or not, if zone transfers are allowed, it will dump all the information and exit happily, otherwise it will brute force it. It is therefore important to properly configure your DNS servers and be aware of the security issues with DNS.
A cache usually contains a mapping of IP-addresses to hostnames which are saved during recent lookups so that the resolver does not have to fetch the IP address again and again. They use multiple servers to serve the request as one server is generally not capable of handling all the requests. However before performing a brute force it would be better to actually check if Wildcard entries are enabled or not. Usually one of these servers will be the Master server and the other one will be the slave server.
We need to supply Fierce with a wordlist containing a list of all the possible subdomain names (for e.g.
Dawno temu stworzylem narzedzie, ktore ulatwia pozyskiwanie tego typu danych z Binga.Jako ze soft lezal juz od dluzszego czasu niemalze zapomniany postanowilem go nieco odswiezyc i udostepnic dla wszystkich.
However, I recently found a free network device simulator at Jalasoft,  which, once running, allows several devices to be simulated. In the information gathering stage of a penetration test of a website, it is important to identify the subdomains and the IP-addresses corresponding to them.
Hence to stay in sync with each other, the slave server must query the Master server and fetch the latest records after a specific period of time.
Hence this kind of information increases our attack vector by a fair amount, an amount which cannot be ignored.


As soon as it finds the IP-address it returns the IP-address back to the user and also caches it for it’s future use.
If this is the case for some random subdomains, then we can clearly say that Wildcard entries are enabled for this domain.

A properly configured nameserver should only be allowed to serve requests of Zone transfer from other Nameservers of the same domain.

However if the server is not configured properly it will serve all requests of Zone transfer made to it without checking the querying client. If it resolves to a different IP-address then we are sure that this subdomain actually exists. If wildcard entries are not set , we do the same thing and see if we get response from any subdomain we query.

Jakis czas temu mozna bylo przeczytac na forach i blogach jakoby Google banowalo cale adresy IP, ze wzgledu na zbyt duza akumulacje stron spamerskich.
Wielu specow seo twierdzilo takze, ze takie zle sasiedztwo moze miec wplyw na widocznosc strony w SERPach, takze na ogolny Trust Rank. Brak twardych dowodow na potwierdzenie tego typu sformulowan, natomiast ja jestem srednio przekonany do tego, moze byc tak jak pisza, natomiast z pewnoscia sa to sporadyczne przypadki gdzie 99% stron hostowanych na IP nosi znamiona spamerstwa lub robi inne przegiecia. Kurcze, jesli masz problem ze 100 znakami, to az strach pomyslec co bedzie z wpisami do katalogow czy precli gdzie limit jest o wiele wiekszy.Jak widze takie wypowiedzi z linkiem reklamowym w tresci to oczywiscie. Limit jest przeznaczony dla spamerow, jesli ktos nie potrafi napisac 100 znakow to wylacznie zle o nim swiadczy, choc nie kazda wypowiedz krotsza jest niewartosciowa, to jednak jesli ktos ma checi i umiejetnosci to rozbuduje swa wypowiedz i bez problemu spelni wymog 100 znakow. Napisalem riposte nie po to by ci dogryzc, ale aby zwrocic uwage na jedna rzecz - ze dla chcacego nic trudnego, a dla spamera nawet te marne 100 znakow stanowi zapore nie do przejscia.Ps. Problem najprawdopodobniej lezy w kluczu, albo jest niepoprawnie przepisany, albo wyczerpales limit, albo klucz zostal zablokowany z innego powodu.
Jak blad sie znowu powtorzy opisz co sprawdzales (jaki IP lub Host), podaj tresc komunikatow o bledach. Niestety nie jestem w stanie sprawdzic, jak aplikacja zachowuje sie w systemie Windows 8 64bit.
Jak tylko bede mial mozliwosc przetestowac ja w tym srodowisku i wychwycic wszelkie niedociagniecia, wypuszcze stosowna poprawke, na ten moment jednak z racji braku dostepu do Win8 nie przewiduje wypuszczenia fixow. Moge tylko powiedziec, ze w systemach Windows XP, Windows Vista 32bit oraz Windows 7 64bit aplikacja funkcjonuje poprawnie.
