Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated: 1 00:00:00,900 --> 00:00:07,320 And the previous lecture we covered how to store our progress when going through a large wordlist. 2 00:00:07,340 --> 00:00:14,150 This allows us to pause and Richoux so that we can stop our cracking session and then come back at a 3 00:00:14,150 --> 00:00:19,790 different time and then start the session from where we left which is very handy when we have a large 4 00:00:19,790 --> 00:00:21,900 wordlist. 5 00:00:21,890 --> 00:00:27,290 Another issue that we might face when you use an a large wordlist is the disk space. 6 00:00:27,320 --> 00:00:32,960 So a large word list would basically just take a lot of space from our desk. 7 00:00:33,740 --> 00:00:42,700 The solution to this is to generate the wordlist use and crunch and pass it on the fly to aircraft N-G. 8 00:00:42,740 --> 00:00:47,900 So basically we're going to be use in crunch to create the wordlist like we've seen before but instead 9 00:00:47,900 --> 00:00:54,550 of saving the wordlist on disk we're going to make it produce the wordlist on screen. 10 00:00:54,680 --> 00:01:01,400 So the result is going to be very similar to what we got when we opened our wordlist with John the Ripper 11 00:01:01,430 --> 00:01:08,990 and the previous lecture and then we're going to pipe that output to aircraft energy which will read 12 00:01:08,990 --> 00:01:16,390 that as input and process the wordlist on the fly as it's being generated on crunch. 13 00:01:16,910 --> 00:01:23,280 This way the wordlist will not be stored in a specific file and it won't take a lot of disk space. 14 00:01:24,290 --> 00:01:27,470 Now let me show you how to do that and it's going to become more clear. 15 00:01:29,610 --> 00:01:34,650 So first of all before I do the whole command I'm just going to show you the command that we usually 16 00:01:34,650 --> 00:01:43,150 use with crunch so easily do crunch and then we do the minimum number of characters followed by the 17 00:01:43,150 --> 00:01:44,930 maximum number of characters. 18 00:01:46,570 --> 00:01:51,610 And I'm going to set both to eight because this is the minimum number of characters that you can use 19 00:01:51,800 --> 00:01:54,780 and with WPA a password. 20 00:01:54,790 --> 00:01:59,230 Then we usually specify the characters to use to generate the wordlist. 21 00:01:59,230 --> 00:02:04,930 Now I'm not going to specify any characters right now because I want to use all the characters so if 22 00:02:04,930 --> 00:02:13,220 I don't specify any characters Cranch will use A B C D F G all the way up to Z by default. 23 00:02:13,330 --> 00:02:20,310 So all I have to do now is just do minus 0 to specify the file to save the wordlist too. 24 00:02:20,380 --> 00:02:30,180 And let's just say to all takes the now I'm going to hit enter and as you can see this file is going 25 00:02:30,180 --> 00:02:35,350 to be huge is going to be one terabyte one thousand seven hundred fifty gigabytes. 26 00:02:35,520 --> 00:02:37,500 And this much megabytes. 27 00:02:37,500 --> 00:02:39,540 So it's going to be a huge file. 28 00:02:39,600 --> 00:02:47,130 And I actually don't have enough space on my desk to store that file so I'm going to do Control-C And 29 00:02:47,130 --> 00:02:52,460 what I'm going to do right now is I'm going to run the same command and I'm just going to omit the minus 30 00:02:52,830 --> 00:02:54,050 argument. 31 00:02:54,660 --> 00:02:56,810 So what I'm doing right now is crunch. 32 00:02:57,090 --> 00:03:00,820 I'm telling it that I want you to generate passwords of length 8. 33 00:03:01,140 --> 00:03:06,690 And I didn't specify any characters because I wanted to use all characters A to Z. 34 00:03:06,690 --> 00:03:12,380 Now if you want to use specific characters you can just type them in here A B C D F G 1 two three. 35 00:03:12,540 --> 00:03:13,940 As I showed you before. 36 00:03:15,870 --> 00:03:20,280 So I'm going to hit enter with this and you'll see that it's still telling me that this is going to 37 00:03:20,280 --> 00:03:26,450 take one terabyte 1750 gigabytes but it's displaying the results on screen. 38 00:03:26,460 --> 00:03:28,500 It's not storing it in a file. 39 00:03:28,800 --> 00:03:36,150 And if we let this run for a long period of time it'll actually display all possible combinations of 40 00:03:36,150 --> 00:03:42,850 characters that have a length of eight characters and contain the characters A to Z. 41 00:03:43,410 --> 00:03:47,150 Now I'm going to do Control-C to this because this is not useful for me. 42 00:03:47,220 --> 00:03:48,750 I'm just doing this to show you. 43 00:03:48,990 --> 00:03:55,260 But if you notice the output right now is very similar to the output that I got in the previous lecture 44 00:03:55,290 --> 00:04:00,870 when I opened my wordlist use and John the Ripper when we were doing the pause and resume process. 45 00:04:02,100 --> 00:04:07,340 So you can see that the result is being displayed on screen for Amena which is very cool. 46 00:04:07,350 --> 00:04:11,160 So what I want to do right now is I want to pipe this result. 47 00:04:11,430 --> 00:04:14,910 So we usually pipe using this character like we've seen before. 48 00:04:15,980 --> 00:04:21,490 So what I want to do right now is I want to pipe the result of this command to aircraft engine. 49 00:04:21,940 --> 00:04:28,430 And like I said earlier this command is producing a result very similar to the result that we got from 50 00:04:28,430 --> 00:04:36,050 John in the previous lecture which means the output right now is exactly the same output that we got 51 00:04:36,320 --> 00:04:38,790 from John in the previous lecture. 52 00:04:39,230 --> 00:04:44,900 So the command that we're going to be passing this to can be exactly the same command that we used in 53 00:04:44,900 --> 00:04:46,010 the previous lecture. 54 00:04:46,190 --> 00:04:47,350 And it should work. 55 00:04:48,230 --> 00:04:56,070 Therefore all I'm going to do is I'm going to do aircraft and G and I'm going to give it the OBSS idea 56 00:04:56,320 --> 00:05:03,340 of my target network then I'm going to give it minus W.T. give it the wordlist. 57 00:05:03,340 --> 00:05:09,640 And just like I did in my previous lecture I'm going to do a dash to tell it that use the output of 58 00:05:09,640 --> 00:05:14,730 the previous command as the input for the wordlist. 59 00:05:14,890 --> 00:05:21,780 Then I'm going to give it the handshake file which is called handshake 0 1 cup and that's it. 60 00:05:21,780 --> 00:05:23,600 I'm good to go. 61 00:05:23,640 --> 00:05:25,600 So we're doing a crunch. 62 00:05:25,620 --> 00:05:26,220 Eight eight. 63 00:05:26,220 --> 00:05:29,090 To generate passwords of length 8 from 8 izzi. 64 00:05:29,280 --> 00:05:35,610 And again you can use any crunch command right here you can use any combination any characters any pattern 65 00:05:35,790 --> 00:05:42,060 exactly the same way that I showed you and the crunch lecture then we're not using the minus option 66 00:05:42,060 --> 00:05:44,960 because we don't want to save anything on disk. 67 00:05:45,030 --> 00:05:52,860 We want the result to be displayed on screen and then we're piping that result to aircraft N-G. 68 00:05:53,040 --> 00:05:59,190 Now two aircraft ngi were given that actually should not have a space here. 69 00:05:59,280 --> 00:06:06,720 So we're giving it the best idea of the target network we're given at the dictionary and we're not actually 70 00:06:06,720 --> 00:06:10,180 given a name for the dictionary we're only giving it a dash. 71 00:06:10,290 --> 00:06:16,560 And this is because we're telling it that I want you to use the output of the previous command as the 72 00:06:16,560 --> 00:06:17,550 input. 73 00:06:17,610 --> 00:06:23,460 So this is exactly like we did in the previous lecture and then we're given a file that contains the 74 00:06:23,460 --> 00:06:24,710 handshake. 75 00:06:25,350 --> 00:06:30,700 Now if I enter I misspelled aircraft. 76 00:06:30,980 --> 00:06:33,610 So it's like this. 77 00:06:33,800 --> 00:06:34,760 Now if I hit enter 78 00:06:38,390 --> 00:06:46,010 and as you can see now aircraft engine is working it's taken the passwords generated by crunch on the 79 00:06:46,010 --> 00:06:49,280 fly and using them as the dictionary. 80 00:06:49,430 --> 00:06:54,530 So the wordlist is not being stored on my desk my desk will not get full. 81 00:06:54,650 --> 00:06:59,360 And this way we'll be able to use huge word lists for cracking. 82 00:06:59,390 --> 00:07:05,480 The only problem right now is this word this is really really big and there is no way we can go through 83 00:07:05,480 --> 00:07:07,010 it within one session. 84 00:07:07,160 --> 00:07:15,050 So it would be great if we can save our progress and be able to stop and continue whenever we have the 85 00:07:15,050 --> 00:07:16,510 time. 86 00:07:16,520 --> 00:07:21,680 So in the next lecture I'm going to show you how to combine what we learned in this lecture and in the 87 00:07:21,680 --> 00:07:28,700 previous lecture so that we can use a huge wordlist and use it directly with our crack energy without 88 00:07:28,700 --> 00:07:33,970 saving it on disk and also be able to stop and rescue our progress. 10004
