Dns enumeration dig

You can use the nslookup command interactively to enter a shell from which you can change servers, set query options, and debug DNS. You can also use nslookup non-interactively from the command line to issue simple queries. See nslookup 1Mtcp for more information.

See dig 1Mtcp for more information. Finally, you can use the host command to provide answers to simple host queries. See host 1Mtcp for more information. Here are the commonly used options of nslookup. For a complete list, see the manual page for nslookup 1Mtcp. You can save any of these options in a.

The format of this file, which is searched for each time you invoke nslookupis one set command per line. Here is an example, which sets the query type to address records, the domain to mynet. To issue a simple query from the command line, use one of the following forms of the command:.

Change any desired options by entering set option.DNS reconnaissance is part of the information gathering stage on a penetration test engagement. This is due that most of the organizations are not monitoring their DNS server traffic and those that do they only monitor the zone transfers attempts. On the web there are a variety of tools available that can gather DNS information effectively but in this article we will focus on the DNSRecon which is a tool that was developed by Carlos Perez and it is designed to perform DNS reconnaissance.

This tool is included on backtrack and it is written in python. But what the SRV records tell us? First of all they tell us that Cisco is using VoIP. We understand that because we can see the SIP protocol in use. Also we know that they are using a jabber XMPP and videoconferencing in their infrastructure. We also obtained the IP and the ports that these services are running. Due to the amount of information that can be obtained DNS zone transfer cannot be easily found in nowadays.

To run reverse lookup enumeration the command. Also reverse lookup can be performed against all ranges in SPF records with the command. In the next image you can see the output that produces a reverse lookup in a range of IP addresses. For performing this technique all we have to do is to give a name list and it will try to resolve the A,AAA and CNAME records against the domain by trying each entry one by one.

In order to run the Domain Name Brute-Force we need to type:. This DNS record will often reveal plenty of information. However DNS cache snooping is not happening very often.

DNS Enumeration Techniques in Linux

The command that can be used in order to perform cache snooping is the following:. This technique may unveils internal records if zone is not configured properly. The information that can be obtained can help us to map network hosts by enumerating the contents of a zone. In order to perform the zone walking we need to type the command:.

As we saw in this article the amount of information that can be discovered during DNS reconnaissance is huge. Often misconfigurations on the DNS servers of our client can help us to map the entire network.

You're on the right track, but that syntax doesn't work for me. What works is dig ns. I'm not sure, but I don't believe AXFR requests can be done recursively, hence the need to query the zone's top-level nameserver directly, which is what the ns. The actual hostname will vary.

Save time and headaches by incorporating our attack surface discovery into your vulnerability assessment process.

No brute force subdomain enumeration is used as is common in dns recon tools that enumerate subdomains. We use open source intelligence resources to query for related domain data.

It is then compiled into an actionable resource for both attackers and defenders of Internet facing systems. More than a simple DNS lookup this tool will discover those hard to find sub-domains and web hosts. Over at hackertarget.

This compiles data similiar to DNSDumpster; with additional data discovery. Queries available are based on the membership plan with the number of results subdomains being unlimited.

However, DNS is also one of the most frequently attacked protocols, where different types of DNS attacks are spread from home users to small, mid and large companies. We all know that DNS servers are basically computers connected to the Internet, and that helps us to resolve hostnames into IP addresses.

DNS Enumeration: Top DNS Recon Tools and Techniques

DNS enumeration is one of the most popular reconnaissance tasks there is for building a profile of your target. Once DNS enumeration is completed, unauthenticated users may use this information to observe internal network records, grabbing useful DNS information that provides the attacker access to a full DNS map.

However, that was only focused on subdomains. Once again, our beloved dig command comes to the rescue, helping us perform DNS enumeration by querying popular types of DNS records. Recon tip: sometimes a particular name server may be configured to reject AXFR requests.

See below:. In the case of a successful DNS transfer, you should be able to get the full DNS zone for the given domain name, as you see below—notice this time we are using -l option, which is another way to list all DNS records from a domain name—while testing the vulnerable site zonetransfer. Available in most distros, including Ubuntu, Fedora, and of course, Kali Linux, it offers an easy syntax for all who are performing reconnaissance tasks.

Apart from that, it also allows you to perform Google scraping using Google dorks such as allinurl: -www site:domain, launch brute force subdomain reconnaissance attacks using word lists, and get a full list of C class domain network ranges. This time it will help us reveal DNS information from a remote domain name. By using the dns-brute scriptNmap will attempt to enumerate DNS hostnames by brute forcing popular subdomain names.

In this case, we did it against microsoft. Fierce is another great DNS reconnaissance tool. Written in Perl, Fierce offers numerous options for performing DNS enumeration by scanning domains in just minutes. Its syntax is pretty easy, as you can see:. Fierce was able to discover a few subdomains, along with NS records, and attempted to run a DNS transfer, which obviously failed.

By adding the —wide, you can also extend the fierce scan to the entire class C after finding any matching hostnames in that class C. This can take a lot of time to finish, especially on networks with a lot of hosts, so keep that in mind.
