1 00:00:10,270 --> 00:00:16,840 Let us continue with the information gathering practicals in the spectacle, we will gather information 2 00:00:16,840 --> 00:00:24,580 using the NSA look and let's look up the network administration command line tool available in many 3 00:00:24,580 --> 00:00:30,760 computer operating systems for creating the domain name system, obtain the domain name or the IP address 4 00:00:30,760 --> 00:00:33,940 mapping or the D.A. records of a particular website. 5 00:00:34,570 --> 00:00:38,150 The name and its lookup means name server lookup. 6 00:00:39,280 --> 00:00:44,470 So for this look, a practical we will use the command prompt in windows. 7 00:00:46,650 --> 00:00:50,420 Just go to the search button and type ACMD over there. 8 00:00:58,720 --> 00:01:02,800 On the Newcomen from type, and let's look up and press enter. 9 00:01:04,640 --> 00:01:11,180 This display is the default server and its address assigned to the Windows Server machine, in the end, 10 00:01:11,180 --> 00:01:21,250 let's lookup in practice more type set space type is equal to and present setting the type as a configured 11 00:01:21,260 --> 00:01:24,440 in this lookup query for the IP address of the given domain. 12 00:01:25,360 --> 00:01:31,570 Tiger, the tiger domain as w w w are certified hacker, dot com and press enter. 13 00:01:37,470 --> 00:01:42,740 This resolves the IP address, and this was the result, as you can see on the screen. 14 00:01:45,030 --> 00:01:54,410 Now we will find the canonically for finding the canonically type said space type is equal to see name 15 00:01:54,570 --> 00:02:01,140 and press enter the canonical name lookup is done directly against the government's authority to name 16 00:02:01,140 --> 00:02:07,230 server and lists that C name records for the room in here type 34 Hecho dot com. 17 00:02:07,740 --> 00:02:13,950 Remember, don't type w w w here as we are typing the domain name. 18 00:02:13,950 --> 00:02:22,170 While this returns, the domains authoritative name server along with the mail server address as shown 19 00:02:22,170 --> 00:02:22,830 on the screen. 20 00:02:24,780 --> 00:02:30,030 Since you have obtained the authority to name server, you will need to determine the IP address of 21 00:02:30,030 --> 00:02:34,550 the name server now issued a command set space type is a. 22 00:02:39,660 --> 00:02:47,730 You can see the primary name server in the results before, as anyone, one blue dot com type and S1 23 00:02:47,880 --> 00:02:51,890 or Bluejuice dot com is the primary name, server and space center. 24 00:02:53,510 --> 00:02:59,470 This returns the IP address of the server, as shown on the screen, the authority to name servers, 25 00:02:59,470 --> 00:03:01,620 stores, the records associated with the domain. 26 00:03:02,090 --> 00:03:08,450 So if an attacker can determine the authority to name server that is the primary name server and obtain 27 00:03:08,450 --> 00:03:14,330 its associated IP address, the attacker might attempt to exploit the server to perform attacks like 28 00:03:14,330 --> 00:03:17,720 those deros, your redaction and so on. 29 00:03:18,680 --> 00:03:20,330 This is all for this practical. 30 00:03:22,210 --> 00:03:26,040 In the next spectacle, they will gather information using Shora.
