1 00:00:00,240 --> 00:00:06,250 Hello, everybody, welcome to my advanced ethical hacking, networking, penetration testing, costing. 2 00:00:17,170 --> 00:00:25,880 Welcome to the application challenging Oct 13, we believe that you have already downloaded and extracted 3 00:00:25,880 --> 00:00:27,960 it so we can come back here. 4 00:00:28,420 --> 00:00:29,740 Now we will study it. 5 00:00:29,740 --> 00:00:34,680 So but first thing first, let me close this because we don't need it anymore. 6 00:00:34,690 --> 00:00:38,330 So, yeah, we don't need it anymore. 7 00:00:38,350 --> 00:00:43,510 We just say, OK, we just say okay. 8 00:00:43,570 --> 00:00:45,640 And we can move them to Josh. 9 00:00:46,060 --> 00:00:50,320 So I'll move to Josh, move to Josh 10 00:00:52,820 --> 00:01:00,150 or before moving to try to let me try, let me try something. 11 00:01:00,340 --> 00:01:02,030 If everything was working fine. 12 00:01:03,320 --> 00:01:04,870 And. 13 00:01:07,160 --> 00:01:17,990 Preaching to the choir episode one to 18, one on duty in Syria and the war on cancer. 14 00:01:18,050 --> 00:01:18,360 Goodbye. 15 00:01:18,620 --> 00:01:22,820 OK, so that's because we didn't put that not all right. 16 00:01:22,820 --> 00:01:28,600 So we can now put it put them to Josh Afrik. 17 00:01:29,300 --> 00:01:31,180 So let's come here. 18 00:01:32,650 --> 00:01:34,310 I can put this to you as well. 19 00:01:34,990 --> 00:01:43,990 So right now, let's try to open this application by pressing button and it says that into your password. 20 00:01:43,990 --> 00:01:46,540 Just just want to see one password. 21 00:01:46,540 --> 00:01:50,860 The password I was looking for was twenty three. 22 00:01:52,470 --> 00:01:57,840 Oh, nine, let me increase it for you, 20 to eight or nine. 23 00:01:58,260 --> 00:02:00,180 Okay, so let me please. 24 00:02:01,020 --> 00:02:02,780 Okay, let me try it again. 25 00:02:03,930 --> 00:02:06,140 Let me take a number of the. 26 00:02:06,960 --> 00:02:07,820 Wait a minute. 27 00:02:09,260 --> 00:02:09,530 Okay. 28 00:02:10,950 --> 00:02:12,000 Now I can put into. 29 00:02:13,810 --> 00:02:20,770 One person because know we're looking for now is to create one again, one last time. 30 00:02:21,990 --> 00:02:22,630 Richard. 31 00:02:24,710 --> 00:02:28,840 OK, let me put up 32 00:02:30,530 --> 00:02:37,750 an OK, as you can detect that as many times we enter a new password. 33 00:02:38,120 --> 00:02:42,340 So it says that the password I was looking for was something new. 34 00:02:42,860 --> 00:02:50,240 You see, every every time you see something new, therefore, let's go to open that application in 35 00:02:50,240 --> 00:02:56,420 order and in ADA and so that we can try for this takes one password. 36 00:02:56,420 --> 00:03:05,440 The person I was looking for was OK, so we closed it and now we're doing it to Ida over here. 37 00:03:08,500 --> 00:03:16,900 We are waiting a little bit and take on, OK, so now we just waiting to put it here like this. 38 00:03:17,950 --> 00:03:19,960 So we are waiting. 39 00:03:22,050 --> 00:03:22,680 We are waiting. 40 00:03:24,280 --> 00:03:26,520 Until we see the Eidelman is here. 41 00:03:29,110 --> 00:03:29,490 OK. 42 00:03:32,300 --> 00:03:32,820 Perfect. 43 00:03:32,990 --> 00:03:36,760 Everything is alright because we see Aly is here. 44 00:03:37,460 --> 00:03:41,150 Well, now we're going to try to analyze the code. 45 00:03:45,390 --> 00:03:54,290 OK, so let's analyze it, let's bring this here to see what kind of strings are there. 46 00:03:55,360 --> 00:04:00,880 OK, so we thought we'd start seeing some so we can just stop it in. 47 00:04:02,230 --> 00:04:03,340 Welcome to System. 48 00:04:03,340 --> 00:04:06,730 Application is working if you just move the upset. 49 00:04:07,090 --> 00:04:10,770 Welcome to Stila Dwight Kay. 50 00:04:11,350 --> 00:04:12,700 Let's check below. 51 00:04:13,750 --> 00:04:18,580 Enter Password Care and next. 52 00:04:18,650 --> 00:04:23,680 Okay, so now it is. 53 00:04:23,830 --> 00:04:26,750 It is jumping to the location 40. 54 00:04:26,890 --> 00:04:28,210 Let me increase it for you. 55 00:04:32,570 --> 00:04:41,700 So it is if, John, if that jump if we call Zuhal, jump here, jump to this location, if you will, 56 00:04:41,840 --> 00:04:47,450 so it jumps here and it's going down down below. 57 00:04:47,750 --> 00:04:55,950 Jump, jump to this location, if not impossible to this location is the new outside. 58 00:04:55,970 --> 00:04:56,960 Let me check it. 59 00:04:59,750 --> 00:05:09,260 So as you can see that here, we don't need even to come back here anymore because here there are no 60 00:05:09,260 --> 00:05:09,830 codes. 61 00:05:09,830 --> 00:05:20,250 So we can just come back here and because everything so the place that the green goes is still here. 62 00:05:20,390 --> 00:05:24,730 OK, so we don't even need to go there. 63 00:05:25,490 --> 00:05:29,420 So we will scroll down, scroll down, scroll down. 64 00:05:29,510 --> 00:05:32,780 We can put it in this and go, OK, scroll down. 65 00:05:33,110 --> 00:05:40,340 If not equal to zero to somewhere, if not equal to zero would jump to this location. 66 00:05:40,340 --> 00:05:43,830 OK, John, we've never got to jump on this occasion, OK? 67 00:05:44,360 --> 00:05:53,660 And the old line, the old line from the first node when this node jumps here. 68 00:05:54,880 --> 00:05:59,200 Jumps here, so it jumps here if it is equal to zero. 69 00:05:59,230 --> 00:06:00,290 Let me check it for you. 70 00:06:00,850 --> 00:06:03,940 It it it jumps. 71 00:06:03,940 --> 00:06:08,330 It jumps here if it is not equal to zero because it's the opposite. 72 00:06:08,350 --> 00:06:13,440 Now, when it is Jay-Z, it's jump here if we will change it and put. 73 00:06:13,450 --> 00:06:15,150 And that means it will jump here. 74 00:06:15,460 --> 00:06:17,630 So let's go down again below. 75 00:06:17,650 --> 00:06:18,790 It drops below. 76 00:06:20,020 --> 00:06:21,400 Below, below, below, below me. 77 00:06:21,400 --> 00:06:26,560 Lawyers let's take well those are wall lines or gun. 78 00:06:28,340 --> 00:06:32,660 Okay, so you will see. 79 00:06:33,610 --> 00:06:34,870 Let's check again. 80 00:06:36,200 --> 00:06:44,620 OK, let's check again the main thing to look at this jump, jump to this location, 14, 15 to 24. 81 00:06:45,160 --> 00:06:52,890 Okay, let's come back here, John, if not equal to this jump here, one password. 82 00:06:53,440 --> 00:06:54,040 All right. 83 00:06:54,130 --> 00:06:58,500 So let us start the application again. 84 00:06:58,510 --> 00:06:59,050 I forget. 85 00:06:59,050 --> 00:07:00,490 How was it OK? 86 00:07:03,940 --> 00:07:05,920 Blah, blah, blah. 87 00:07:07,630 --> 00:07:18,280 The person I was looking for was something so that you can hear that, OK, this is the text. 88 00:07:18,430 --> 00:07:28,090 This is the text that was approved and the application and the application that push those new numbers. 89 00:07:28,090 --> 00:07:29,030 So they are here. 90 00:07:29,500 --> 00:07:36,670 They are Whitehill Integer and offset and moves it on this E.S.P register. 91 00:07:37,570 --> 00:07:42,320 OK, so we can go down, go down, go down, get down to see what is the end. 92 00:07:42,430 --> 00:07:43,900 So this is the end. 93 00:07:43,900 --> 00:07:44,110 We. 94 00:07:44,650 --> 00:07:53,590 Now let's come back here because we do need to find if any text here and the headline. 95 00:07:56,560 --> 00:07:58,370 OK, so let's come back here. 96 00:07:59,610 --> 00:08:12,100 OK, now what we can see that all those operations were made just way above and then now from this node, 97 00:08:12,580 --> 00:08:22,540 from this node, if it is if jump to this powered jump, if you will, to this location. 98 00:08:22,540 --> 00:08:30,300 And therefore, we've got to change this to to Jay Z Oge so that it jumps over here. 99 00:08:30,550 --> 00:08:35,490 And if something else is needed so that we can get the application, we will do it. 100 00:08:35,500 --> 00:08:40,330 But first thing first we're going to do is by changing this disaccord. 101 00:08:40,330 --> 00:08:46,180 I mean this function, we will change it to the opposite. 102 00:08:46,570 --> 00:08:57,400 OK, so we wait, we just click and come back here and Buche program assemble. 103 00:08:59,890 --> 00:09:05,850 And again, we use the N word. 104 00:09:06,320 --> 00:09:17,320 OK, we can control and we put it on DRIN, we click on OK, now we have to apply define, we apply 105 00:09:17,330 --> 00:09:17,620 it. 106 00:09:17,780 --> 00:09:19,720 Let's apply it over here. 107 00:09:20,260 --> 00:09:20,840 ABSs. 108 00:09:23,560 --> 00:09:25,510 Apply patches to input file. 109 00:09:26,030 --> 00:09:30,000 OK, so now let me put it back a little bit. 110 00:09:31,830 --> 00:09:33,210 So that you can see everything. 111 00:09:34,770 --> 00:09:41,520 Well, so now we can come back to the application and let's try to ruin it. 112 00:09:43,130 --> 00:09:49,490 Or if you want, you can just want it over here, guys, so it's not a problem, but we just want our 113 00:09:49,540 --> 00:09:53,450 stuff or stuff to be reloaded again and again. 114 00:09:53,450 --> 00:10:01,830 So we just apply to today applied the change, the modifications to the federal system, the fines that 115 00:10:01,830 --> 00:10:02,360 we get it. 116 00:10:03,330 --> 00:10:05,990 OK, now let me put anything in em. 117 00:10:06,710 --> 00:10:13,910 And one password, the password, the password I was looking for was days. 118 00:10:14,300 --> 00:10:18,150 So that means something still need to be changed. 119 00:10:18,560 --> 00:10:22,590 So as you can clearly see that it compares something white. 120 00:10:22,850 --> 00:10:30,010 Yes, it is a compared to something and after it compares with X register. 121 00:10:30,290 --> 00:10:32,140 OK, so we get to figure it out. 122 00:10:35,190 --> 00:10:43,500 He and this broke in this node, we see that it be something, as we have said, and let's go it up 123 00:10:44,400 --> 00:10:55,590 again in this blog, it compares something and push it and compare it with the X. Let's go all over 124 00:10:56,220 --> 00:10:56,880 again. 125 00:10:57,300 --> 00:10:58,170 The same thing. 126 00:10:59,440 --> 00:11:08,050 Again, composed again, composed again and again and again and again, that's crazy. 127 00:11:08,500 --> 00:11:19,420 OK, so very sound of it that we see that some populations are made into this, not because it after 128 00:11:19,930 --> 00:11:33,100 moving this Vibora Bruce MBP on on X, it compares is voidable on E it with X and then after it jumps 129 00:11:33,520 --> 00:11:39,540 to somewhere with the green green line if not equal to zero. 130 00:11:39,880 --> 00:11:49,090 Therefore since we were here, when we change this, we prevent that application to go to Dysport because 131 00:11:49,090 --> 00:11:54,750 when it it is jumping if equal to zero, it jumps over here. 132 00:11:55,270 --> 00:11:58,000 That means it jumps here. 133 00:11:59,730 --> 00:12:04,350 As you can see, so we got to figure it out. 134 00:12:04,920 --> 00:12:05,340 OK? 135 00:12:07,570 --> 00:12:16,900 As we can see, that something is different in this application and what is that thing when it jumps 136 00:12:17,050 --> 00:12:24,470 to Dysport, that means it is jumping or equal to jumping, if equal to zero in jumps over here. 137 00:12:25,450 --> 00:12:32,470 But what we can see the cords jump in here when we don't get the password. 138 00:12:33,070 --> 00:12:35,070 Exactly, because this is the wood line. 139 00:12:35,080 --> 00:12:41,380 And when we type here, everything, anything, it it automatically jump. 140 00:12:42,070 --> 00:12:43,900 Jump goes to this point. 141 00:12:43,930 --> 00:12:45,750 Let me show you the text again. 142 00:12:46,270 --> 00:12:52,210 It automatically goes to Despard, which is followed by the red line. 143 00:12:52,360 --> 00:12:55,630 You see, before we go into what? 144 00:12:56,710 --> 00:13:01,360 The process so that it goes over here, so let's do it. 145 00:13:05,540 --> 00:13:11,120 Therefore, when we won the application, what we get, we automatically get a new message and then 146 00:13:11,120 --> 00:13:16,060 that message is form the red line now, not from the green line. 147 00:13:16,340 --> 00:13:21,520 Therefore, we should change the court's direction for this. 148 00:13:22,220 --> 00:13:27,090 We come here and oops moment mentality. 149 00:13:27,590 --> 00:13:39,170 It can come up and we would change it to not equal zero zero program again sambal. 150 00:13:43,230 --> 00:13:43,800 Within. 151 00:13:46,100 --> 00:13:51,710 OK, so now again, highlighted in green color. 152 00:13:57,600 --> 00:14:06,210 OK, so put it in green, because we have this change, that means we will identify which nodes we have 153 00:14:06,210 --> 00:14:07,290 already made or change. 154 00:14:08,430 --> 00:14:17,460 Now let's go jump to anything if it's not equal. 155 00:14:17,910 --> 00:14:19,830 Let's try to find out anything, guys. 156 00:14:20,570 --> 00:14:23,280 We will find it just for the first line. 157 00:14:23,980 --> 00:14:27,990 OK, so let me come here first thing first. 158 00:14:28,050 --> 00:14:30,540 Let me highlight the good line. 159 00:14:31,790 --> 00:14:35,950 OK, so this one, the first one, OK, let's come here. 160 00:14:37,170 --> 00:14:43,650 Again, let's come here, let's come here it is this one to see where it is jumping. 161 00:14:44,790 --> 00:14:47,170 You see, it doesn't go here. 162 00:14:47,580 --> 00:14:54,750 So all those one, two, three, four, five green light lines, they jump. 163 00:14:55,170 --> 00:14:58,230 They jump directly to another location. 164 00:14:58,230 --> 00:14:59,930 But we want them to jump here. 165 00:15:00,330 --> 00:15:09,090 So we got to change those due note without changing the nodes we will never reach here. 166 00:15:09,390 --> 00:15:15,960 So we have to follow the path so that we first could follow the path that we need so that they don't 167 00:15:15,960 --> 00:15:16,830 jump over here. 168 00:15:16,830 --> 00:15:20,990 They jump in front of the process and then to the day job here. 169 00:15:21,330 --> 00:15:28,870 So to do so, we are going to use the same thing and light in the opposite code. 170 00:15:30,320 --> 00:15:33,900 OK, so now we are here. 171 00:15:34,740 --> 00:15:38,160 Instead of going here, it should go here. 172 00:15:39,060 --> 00:15:39,870 The same thing. 173 00:15:40,470 --> 00:15:41,240 Go here. 174 00:15:41,490 --> 00:15:43,080 Oh, wait a minute. 175 00:15:43,080 --> 00:15:45,820 I can make it bigger for you get. 176 00:15:47,570 --> 00:15:53,390 Indeed, program at Progun, a symbol. 177 00:15:54,840 --> 00:15:58,890 And not equal, not equal. 178 00:15:59,080 --> 00:16:03,530 OK, I'll just put it this way. 179 00:16:03,910 --> 00:16:04,320 OK. 180 00:16:05,990 --> 00:16:07,310 We put it in green. 181 00:16:09,420 --> 00:16:13,720 And do the same thing again, we avoid. 182 00:16:14,040 --> 00:16:17,410 We want to avoid the green light from going this way. 183 00:16:17,640 --> 00:16:24,530 It was go to this node, so it did not let me come here. 184 00:16:24,540 --> 00:16:25,110 It did. 185 00:16:27,390 --> 00:16:28,580 A symbol. 186 00:16:29,700 --> 00:16:39,510 And yeah, g e if you want A, you can just put it OK, you see, it's the same like Jazy so it doesn't 187 00:16:39,510 --> 00:16:44,700 matter C automatically it takes like Jazy, so 188 00:16:47,800 --> 00:16:52,590 green color and the same thing will avoid the third line. 189 00:16:52,590 --> 00:16:55,410 It turned green light to go this way. 190 00:16:55,810 --> 00:16:58,650 So again, indeed. 191 00:17:01,470 --> 00:17:14,820 Peukan Biologies, Azango and you, is that the end and yep, click on OK console and now again, green 192 00:17:14,820 --> 00:17:15,600 decks. 193 00:17:16,140 --> 00:17:17,370 Guinot I mean. 194 00:17:18,610 --> 00:17:20,290 You can we can come down below. 195 00:17:22,160 --> 00:17:30,380 Below, below, below, below, below is so the next red green light, so we can change it as well. 196 00:17:30,410 --> 00:17:35,180 But first thing first, the assembled batch assemble. 197 00:17:36,850 --> 00:17:38,110 It was the not. 198 00:17:40,110 --> 00:17:47,670 And click on console and console and put the green light. 199 00:17:49,290 --> 00:17:49,930 OK. 200 00:17:49,950 --> 00:17:52,560 And do the same thing, guys, so just follow me. 201 00:17:52,620 --> 00:17:53,000 OK? 202 00:18:11,900 --> 00:18:12,680 All right. 203 00:18:16,550 --> 00:18:18,140 Click over here something. 204 00:18:22,700 --> 00:18:23,210 Symbol. 205 00:18:29,800 --> 00:18:30,250 So. 206 00:18:35,780 --> 00:18:42,350 So we identify all the blogs which we have made, which we make or modification, and then the last 207 00:18:43,160 --> 00:18:47,250 we have gone to demotivate or five green lines. 208 00:18:47,760 --> 00:18:50,210 Now let's check. 209 00:18:51,900 --> 00:19:00,300 Before changing it, it was John, if not equal, is equal to this location, and then the position 210 00:19:00,300 --> 00:19:06,720 was followed by going to that line, therefore we put the opposite so that it jumps over here. 211 00:19:07,260 --> 00:19:17,730 And the now then the last one should be we got to avoid the the jumping from going to this location. 212 00:19:18,090 --> 00:19:24,810 It should jump to this node because after jumping to this node, we have already modified this. 213 00:19:24,960 --> 00:19:26,880 We avoid it from going that way. 214 00:19:26,880 --> 00:19:29,140 It will go this way and all black. 215 00:19:29,710 --> 00:19:30,210 Right. 216 00:19:30,210 --> 00:19:31,530 So we click here. 217 00:19:32,810 --> 00:19:42,730 We click here again, so we come here and bargepole one sample they send us. 218 00:19:46,780 --> 00:19:48,160 Click on Talk of. 219 00:19:50,740 --> 00:19:52,720 Oil and green. 220 00:19:57,160 --> 00:20:03,340 OK, so now I can put the screen in there to be back for you so that you can see everything. 221 00:20:05,050 --> 00:20:05,590 Great. 222 00:20:06,100 --> 00:20:15,790 Now let us apply the changes and if I'll come back over here and punch program as usual, OK, which 223 00:20:15,790 --> 00:20:17,640 is the input file and cookie. 224 00:20:18,970 --> 00:20:21,160 So we must close. 225 00:20:21,540 --> 00:20:22,960 Oh, Canada. 226 00:20:23,470 --> 00:20:25,060 Yes, I know, I know. 227 00:20:25,060 --> 00:20:33,580 I must close this up with intelligence risk X and let's come back again. 228 00:20:39,540 --> 00:20:51,360 OK, now it's OK, so when I come back here and press into trying to end it again and blah, blah, 229 00:20:51,360 --> 00:21:08,460 blah, Corrick, the password for H.B it is minus one hundred fifteen to two, let me put it like this, 230 00:21:09,000 --> 00:21:12,840 two two five five one seven three. 231 00:21:14,090 --> 00:21:22,670 Oh, it's strange that we will meet again, but never mind all the steps that we have taken should be 232 00:21:22,680 --> 00:21:25,590 called Let me put up or. 233 00:21:27,470 --> 00:21:39,770 The same can be said, no, let me put it in your he did last time I was in the care, let me put it 234 00:21:39,770 --> 00:21:44,330 like this for you and let you put blah, blah, blah. 235 00:21:45,840 --> 00:21:48,540 Blah, blah, blah, blah, enough. 236 00:21:51,260 --> 00:21:53,220 Oh, I see, said no. 237 00:21:53,240 --> 00:21:54,940 So it might be the password. 238 00:21:55,720 --> 00:21:57,560 Let let's try to copy it. 239 00:21:58,220 --> 00:21:58,550 Can a. 240 00:22:04,060 --> 00:22:11,980 OK, so anyways, it's minus one hundred fifteen, so let's let it be like this and let's come back 241 00:22:12,670 --> 00:22:13,450 to all. 242 00:22:14,630 --> 00:22:15,680 Two of our fox. 243 00:22:17,000 --> 00:22:25,670 OK, so you see your very well and it's a good it's application 13, so now we're going to try to type 244 00:22:25,670 --> 00:22:26,210 it here. 245 00:22:27,560 --> 00:22:30,820 One one one five. 246 00:22:31,760 --> 00:22:34,850 And was it one one five of the. 247 00:22:36,260 --> 00:22:50,570 On one one five two two five five one seventy two two five five one zero, he control two two five five 248 00:22:50,600 --> 00:23:04,430 under control, a control X that's coming back here and just posted by click and post and we submit. 249 00:23:04,910 --> 00:23:05,630 So we will see. 250 00:23:08,030 --> 00:23:09,870 Please enter decoyed password. 251 00:23:09,890 --> 00:23:17,980 That means the password is not correct, so we we should try to modify the tax codes. 252 00:23:18,200 --> 00:23:20,580 OK, so let's see. 253 00:23:21,560 --> 00:23:28,710 Or before let us try to put out that minus first and first. 254 00:23:28,730 --> 00:23:35,870 Let me come back here and post it was it was the Williamsburg check again. 255 00:23:39,070 --> 00:23:50,520 Let's try to erase the fact that my news so fast and it's come back here. 256 00:23:52,880 --> 00:23:55,330 And OK, please enter the password. 257 00:23:55,680 --> 00:23:57,230 OK, so we got to figure it out. 258 00:23:57,260 --> 00:23:59,620 Oops, no, no, no, no, no, I don't want you. 259 00:23:59,660 --> 00:24:00,200 Come on. 260 00:24:01,130 --> 00:24:02,740 No, not OK. 261 00:24:02,750 --> 00:24:03,300 So we are here. 262 00:24:03,680 --> 00:24:14,930 So what we can do now, while warning or application, we have seen that it has a minus number so it 263 00:24:15,020 --> 00:24:16,550 can come back again here. 264 00:24:18,080 --> 00:24:23,150 We have done everything properly and quickly jump everything. 265 00:24:25,210 --> 00:24:29,740 From the opposite, OK, OK, good, good, good so far. 266 00:24:30,730 --> 00:24:37,660 OK, so let us come back here and we can try it again with this. 267 00:24:38,940 --> 00:24:40,500 And the. 268 00:24:43,160 --> 00:24:53,630 Okay, minus one one five two two five five one seven three, OK, so this number is signed. 269 00:24:54,230 --> 00:25:00,400 So what is the assigned number is ranked number or assigned integer? 270 00:25:00,950 --> 00:25:01,700 Is that. 271 00:25:03,120 --> 00:25:11,460 And four of that number or in front of that integer, it has either plus or minus when we have a number 272 00:25:11,460 --> 00:25:17,880 which has a minus or plus and minus, that number is sound. 273 00:25:18,420 --> 00:25:28,940 And exactly the opposite is that unsigned number, unsigned number doesn't have any flag and you flag 274 00:25:29,190 --> 00:25:34,370 it doesn't have a minus flag and no a plus flag. 275 00:25:34,390 --> 00:25:44,310 Therefore, we assume that all the numbers which don't have any flags before them, we assume that they 276 00:25:44,310 --> 00:25:52,060 are saying no because they automatically have a plus number in front of them, but which is not within. 277 00:25:52,080 --> 00:25:53,400 So it is unsigned. 278 00:25:53,580 --> 00:25:57,470 OK, so just just to let you know. 279 00:25:57,480 --> 00:25:59,100 So let's go back to our topic. 280 00:25:59,370 --> 00:26:07,050 Auto topic is that we got to figure out a way so that we can enter something in our account so that 281 00:26:07,050 --> 00:26:08,020 we can get the password. 282 00:26:08,250 --> 00:26:11,250 So this number is for us a signed number. 283 00:26:11,250 --> 00:26:18,440 So we get to try to convert it to an unsigned number or two to binary numbers. 284 00:26:18,450 --> 00:26:22,920 So therefore, you can go to Google or to a start page. 285 00:26:23,280 --> 00:26:25,350 And let's come back here. 286 00:26:26,110 --> 00:26:27,010 Let's come back here. 287 00:26:28,020 --> 00:26:36,790 So you go to this website, let me put it like this just a little bit by now, reconvert dot com. 288 00:26:37,440 --> 00:26:40,470 So now it is not secure, but never mind. 289 00:26:40,470 --> 00:26:41,490 So we don't care about it. 290 00:26:41,760 --> 00:26:44,850 We just want to convert or no. 291 00:26:45,360 --> 00:26:46,040 And so that's a. 292 00:26:47,600 --> 00:26:50,340 Yeah, so what do we need? 293 00:26:50,630 --> 00:26:57,950 We need to convert assigned integer, so when same characters and characters and sideshows or there 294 00:26:57,950 --> 00:26:59,580 are a few of them. 295 00:26:59,990 --> 00:27:09,750 So what we need is this one is the minimum is this number one minus, blah, blah, blah, two plus 296 00:27:10,430 --> 00:27:11,080 the fourth. 297 00:27:11,270 --> 00:27:14,690 Let's try to count one, two, three. 298 00:27:15,800 --> 00:27:19,010 Let me put it like this for you again. 299 00:27:20,060 --> 00:27:27,540 So one, two, three, four, five, six, seven, eight, nine, 10. 300 00:27:27,860 --> 00:27:30,290 Okay, let us come back here. 301 00:27:32,010 --> 00:27:36,860 One, two, three, four, five, six, seven, eight, nine, 10. 302 00:27:36,890 --> 00:27:41,060 Therefore, it belongs to that interval to the center of our. 303 00:27:41,060 --> 00:27:42,170 I mean, OK. 304 00:27:50,520 --> 00:27:57,800 OK, so now the next step is the next step will be last step, guys. 305 00:27:58,170 --> 00:28:06,210 So we wanted to show you that you can try to do many things because since you don't know exactly. 306 00:28:07,560 --> 00:28:15,270 Which number that they need, so you're going to try to figure it out, but the consensus is that if 307 00:28:15,270 --> 00:28:27,090 here we see that the password for each page is this with a minus and before this number, that means 308 00:28:27,750 --> 00:28:31,350 this number is for us like a signed number. 309 00:28:31,560 --> 00:28:38,120 So now what we can try to do, since we have tried to enter this password and it didn't work. 310 00:28:38,430 --> 00:28:40,600 So let me check it out again today. 311 00:28:40,830 --> 00:28:50,600 So if I show you so we copy can be OK in a way so we can come back here and come here. 312 00:28:52,460 --> 00:28:53,300 I think we need. 313 00:28:56,190 --> 00:29:02,770 So scroll down to scroll down, we are looking for all Korkin Facebook. 314 00:29:02,790 --> 00:29:13,550 It's minus minus one one legged David Hill instead minus one one five twenty two five five one seven 315 00:29:13,590 --> 00:29:13,740 two. 316 00:29:14,220 --> 00:29:18,150 So we control going to an X and then we're going to pass it here. 317 00:29:18,660 --> 00:29:20,610 So we place it here. 318 00:29:20,640 --> 00:29:22,020 Let's try to see again. 319 00:29:24,260 --> 00:29:26,880 OK, that means these numbers. 320 00:29:27,110 --> 00:29:29,840 This number is not valid, sir. 321 00:29:30,650 --> 00:29:38,980 So we got to find the opposite of this number by converting this signed number to one signed number 322 00:29:38,990 --> 00:29:40,090 and how to do so. 323 00:29:40,430 --> 00:29:43,190 We're going to showing you guys first thing first. 324 00:29:43,190 --> 00:29:52,460 If you know that Java, it would be very helpful for you because we can convert a site number two to 325 00:29:52,460 --> 00:29:54,110 an unsigned number in Java. 326 00:29:54,650 --> 00:30:03,400 So let me try to open my terminal here and I will try to create a job application. 327 00:30:04,850 --> 00:30:22,850 I open terminal and I type something like Dodge Doge H h, h, h, h and B, age 13, that java. 328 00:30:23,440 --> 00:30:33,230 OK, so now I create like this application here in Java and now I'm going to write stuff inside so I 329 00:30:33,230 --> 00:30:34,010 double click it. 330 00:30:35,610 --> 00:30:36,520 Let me get here. 331 00:30:38,140 --> 00:30:46,900 OK, so what we have to do first, you got to figure out that you are Java application in Java is installed 332 00:30:47,020 --> 00:30:49,470 on your system to see it. 333 00:30:49,480 --> 00:30:55,000 You're going to come here on terminal and then you can type this in Java and vision. 334 00:30:55,690 --> 00:30:56,400 And it was into. 335 00:30:58,830 --> 00:31:07,150 We have this version, one that eight guys make sure that you have the vision of one that eight or or 336 00:31:07,170 --> 00:31:15,500 later, so not a dot seven or six, and so some stuff like that to avoid any kind of mistake. 337 00:31:15,780 --> 00:31:20,490 And then you're going to try the same thing again, but not with just Java. 338 00:31:21,540 --> 00:31:23,540 OK, so well done. 339 00:31:23,580 --> 00:31:31,050 Now we can start writing or code, though, for our application is it should be age 13. 340 00:31:31,350 --> 00:31:43,140 So we can type here, let's say in Java, dot Apple, don't start at all and then we can type class 341 00:31:44,130 --> 00:31:45,000 class each. 342 00:31:45,120 --> 00:31:48,510 It should be age 13 and 343 00:31:52,910 --> 00:32:05,760 go budget and then he'll want to make it public for the main public class static type class static and 344 00:32:05,770 --> 00:32:07,980 void main. 345 00:32:08,610 --> 00:32:21,150 Therefore I come here and stream which string and this and all that and like this. 346 00:32:22,560 --> 00:32:27,260 Oh so here we're going to type the code that we want to convert. 347 00:32:27,270 --> 00:32:28,140 So which number. 348 00:32:28,410 --> 00:32:29,310 The number we want. 349 00:32:29,970 --> 00:32:37,970 The number we want to convert is this number minus one one one five and and so on and so on. 350 00:32:38,340 --> 00:32:39,870 So we'll come back here again. 351 00:32:40,710 --> 00:32:45,030 So we type it as integer because it is to be the integer number. 352 00:32:46,970 --> 00:32:55,490 So we dive into Joe Inderjit, let's say integer blah. 353 00:33:11,520 --> 00:33:20,970 Now, we should try to convert it to the unsigned, long integer to do so, we're going to do the same 354 00:33:20,970 --> 00:33:21,420 thing. 355 00:33:21,420 --> 00:33:27,020 And coming here, let me put it a little bit here. 356 00:33:27,750 --> 00:33:28,220 So, 357 00:33:32,280 --> 00:33:32,870 OK, 358 00:33:36,600 --> 00:33:41,100 so integer and we can type one. 359 00:33:45,680 --> 00:33:54,240 OK, now we can type long black one equals what we don't know. 360 00:33:54,260 --> 00:33:56,500 So he I'm going to tell you the formula. 361 00:33:56,510 --> 00:33:59,720 It's that therefore you're going to type. 362 00:34:01,570 --> 00:34:15,660 Blood in an zwar eggs, one, two, three, four, five, one, two, three, four, five, no, sorry. 363 00:34:15,820 --> 00:34:16,540 One, two, three, four. 364 00:34:16,540 --> 00:34:17,250 One, two, three, four. 365 00:34:17,260 --> 00:34:17,740 Come on. 366 00:34:18,310 --> 00:34:19,630 One, two, three, four. 367 00:34:19,630 --> 00:34:20,770 One, two, three, four. 368 00:34:21,520 --> 00:34:22,870 One, two, three, four. 369 00:34:22,870 --> 00:34:31,100 One, two, three, four, eight times both of them and L means long and L and then it wasn't. 370 00:34:31,750 --> 00:34:40,030 Now you just put in the system out system out Gwendoline and then you're going to die of let's say that. 371 00:34:41,070 --> 00:35:01,600 It's say that day, the one unsigned, one signed number four age, the age must be this we don't know 372 00:35:01,600 --> 00:35:01,890 about. 373 00:35:02,370 --> 00:35:14,170 So we would organize so and it's the one OK, and then you put it, we put semicolon. 374 00:35:14,520 --> 00:35:17,220 So let's check again if everything is alright. 375 00:35:17,370 --> 00:35:27,000 So OK, we create a class and then so we and the main board, we put the integer. 376 00:35:27,000 --> 00:35:33,030 So that integer that we have got here, one one five two two five five one seven one. 377 00:35:33,030 --> 00:35:37,740 OK, and then this is a long, long integer. 378 00:35:39,060 --> 00:35:42,390 I mean unsigned long. 379 00:35:42,660 --> 00:35:48,830 So this blah in converting to this long numbers. 380 00:35:48,990 --> 00:35:51,060 So we put out the system. 381 00:35:51,300 --> 00:35:52,740 OK, so let's compile it. 382 00:35:53,400 --> 00:35:54,940 So we're going to come back here again. 383 00:35:55,500 --> 00:36:06,190 So now we type javadoc and it is to be that it it was on edge and this one is the. 384 00:36:07,580 --> 00:36:13,730 And OK, if we get any worse, that means it is compiled and automatically here you're going to see 385 00:36:13,730 --> 00:36:15,520 a class of it. 386 00:36:15,530 --> 00:36:20,710 So let's check where it is, because it must be here. 387 00:36:20,750 --> 00:36:21,650 It should be age. 388 00:36:22,790 --> 00:36:26,030 Is it really is. 389 00:36:42,740 --> 00:36:46,660 Something is wrong, we got to figure it out. 390 00:37:05,680 --> 00:37:06,910 We save an. 391 00:37:09,460 --> 00:37:17,050 OK, now we can compile it, now we can try try to compile it. 392 00:37:18,540 --> 00:37:22,050 Now, automatically, we're going to have a class which is here. 393 00:37:22,170 --> 00:37:30,610 All right, so now we can win it by typing Java and Age and just Blissett tab. 394 00:37:30,780 --> 00:37:33,360 Don't put any extensional in just positive. 395 00:37:35,610 --> 00:37:36,450 We get a no. 396 00:37:37,020 --> 00:37:41,570 The unassigned number for each age must be days. 397 00:37:41,970 --> 00:37:44,190 So we're going to copy it like this. 398 00:37:44,400 --> 00:37:47,310 Let me get a minute copy like this. 399 00:37:48,540 --> 00:37:49,200 Copy. 400 00:37:49,440 --> 00:37:50,870 And we are coming back here. 401 00:37:51,660 --> 00:37:52,350 We will see. 402 00:37:56,430 --> 00:37:57,130 Congrats. 403 00:37:57,930 --> 00:38:06,690 Forty five point has been added, guys, so as you can see that this is where many students like me 404 00:38:06,690 --> 00:38:14,910 and said that, OK, but we have already found a way to trackwork the application or to find a number, 405 00:38:14,910 --> 00:38:15,140 but. 406 00:38:15,540 --> 00:38:16,080 Does it work? 407 00:38:16,110 --> 00:38:25,710 Yes, it is inital it it will be not working because hellbound hackers, they need that they unsigned 408 00:38:25,710 --> 00:38:26,150 number. 409 00:38:26,370 --> 00:38:33,960 So if that number is signed and therefore you have to you have to convert it to an unsigned no long 410 00:38:34,140 --> 00:38:34,440 digit. 411 00:38:34,890 --> 00:38:38,190 So I'm going to show you a quick way. 412 00:38:38,190 --> 00:38:46,200 Some some people can can do it to find this this version of this number as well, because that application 413 00:38:46,200 --> 00:38:57,060 you can if you want, you can say that you're not going to use a.D.A or or Winnipegger to to put the 414 00:38:57,060 --> 00:38:57,980 opposite here. 415 00:38:58,110 --> 00:39:06,390 But that application will require you to run the application 13 at the same time, four to one application 416 00:39:06,390 --> 00:39:07,220 at the same time. 417 00:39:07,230 --> 00:39:11,650 So I'm going to show you and very quickly how to do it. 418 00:39:12,120 --> 00:39:12,810 Me come back. 419 00:39:12,900 --> 00:39:14,400 He was my Windows machine. 420 00:39:17,540 --> 00:39:18,540 Try here. 421 00:39:25,960 --> 00:39:34,480 So let me show you how you can make it so in windows, sometimes it is very it is very needful that 422 00:39:34,480 --> 00:39:43,480 you know how to one many applications at the same time, because sometimes you might want to open Google 423 00:39:43,480 --> 00:39:52,660 Chrome firewall or Firefox or so on some antivirus software or some Photoshop anythings at the same 424 00:39:52,660 --> 00:39:52,930 time. 425 00:39:52,940 --> 00:39:56,140 And then you would want to put them to one of them at the same time. 426 00:39:56,170 --> 00:39:57,120 So how can you do it? 427 00:39:57,130 --> 00:40:01,470 You will create a file and say it as an extension. 428 00:40:01,480 --> 00:40:07,780 But then after that, what you can do, you will write the name of those applications. 429 00:40:07,780 --> 00:40:14,800 But the file that you are going to created must be in the same folder, or if even the software are 430 00:40:14,800 --> 00:40:15,630 not installed. 431 00:40:15,880 --> 00:40:22,180 For example, we have this application application 13 application to it, and so we take it twice because 432 00:40:22,180 --> 00:40:24,460 we want it to be open choice. 433 00:40:24,730 --> 00:40:25,200 All right. 434 00:40:25,600 --> 00:40:27,460 So how can we know that? 435 00:40:27,470 --> 00:40:35,110 We know that because when we open the application, do it with only the book we see in the window. 436 00:40:35,140 --> 00:40:39,410 No, that means it is applied by the time. 437 00:40:39,430 --> 00:40:45,370 So let me just very quickly show you how you can make it to the typical application. 438 00:40:45,370 --> 00:40:48,190 13 desktop desktop. 439 00:40:49,840 --> 00:40:51,980 This application 13. 440 00:40:52,010 --> 00:40:54,550 OK, I can open it with all iboga. 441 00:40:55,750 --> 00:40:59,880 Come here already bigger and OK. 442 00:40:59,910 --> 00:41:02,620 And so open it as an administrator. 443 00:41:03,550 --> 00:41:11,920 Come on, your feelings in a way I don't want, you know, so quickly and as usual. 444 00:41:12,580 --> 00:41:15,770 OK, so let's try to win it. 445 00:41:16,060 --> 00:41:26,350 I just want to show you why this application is based on time interval so I can like they can search 446 00:41:26,380 --> 00:41:30,880 for us to index, search for students to take a look. 447 00:41:30,940 --> 00:41:33,950 Let me check with this one, OK? 448 00:41:34,890 --> 00:41:35,560 And 449 00:41:38,980 --> 00:41:39,640 one person. 450 00:41:39,640 --> 00:41:41,830 One person, one person, one person, one person. 451 00:41:41,860 --> 00:41:44,540 OK, so here we are, the application. 452 00:41:44,860 --> 00:41:45,430 OK. 453 00:41:45,470 --> 00:41:47,050 When you first started it says that. 454 00:41:47,050 --> 00:41:49,720 Welcome to System Application and Thomsons one. 455 00:41:49,720 --> 00:41:55,060 Here we see a time c the window number though for this application. 456 00:41:55,060 --> 00:42:03,350 It depends on the time if you try to open it just once and you will see how it will look like. 457 00:42:03,640 --> 00:42:11,460 Let me show you let me not close it first, but let me go back here to my download folder. 458 00:42:11,470 --> 00:42:13,210 Let me check on my document. 459 00:42:14,410 --> 00:42:20,710 Let me check that in my documents or on download or let me check this first music. 460 00:42:21,340 --> 00:42:23,140 OK, here it might be. 461 00:42:23,410 --> 00:42:26,110 Let me see that to do. 462 00:42:27,700 --> 00:42:29,880 OK, let me say something. 463 00:42:31,210 --> 00:42:31,690 You see. 464 00:42:33,060 --> 00:42:43,030 It is beeping, ta ta ta ta ta, so what we can do now, we should try to open a choice, OK, so to 465 00:42:43,080 --> 00:42:50,850 open it twice, we go to or stop and then we try to enter that. 466 00:42:51,890 --> 00:42:58,430 That application form here, let me show you, we don't need this anymore. 467 00:42:58,820 --> 00:43:00,530 We can try to close this. 468 00:43:01,400 --> 00:43:04,970 OK, you can still be here, of course, but it is still there. 469 00:43:05,690 --> 00:43:08,510 Okay, let me show you how it is. 470 00:43:09,080 --> 00:43:09,700 We shall be. 471 00:43:10,620 --> 00:43:11,750 Ta ta ta ta ta ta ta. 472 00:43:13,280 --> 00:43:16,280 So now bye bye. 473 00:43:16,280 --> 00:43:24,290 Typing the application, which you want choice and then it will, it will open that application according 474 00:43:24,290 --> 00:43:27,940 to the number of times you have written it here. 475 00:43:28,280 --> 00:43:30,700 So but remember it should be in the same folder. 476 00:43:30,980 --> 00:43:31,270 Right. 477 00:43:31,670 --> 00:43:33,740 So let me come back here to meet. 478 00:43:35,430 --> 00:43:43,710 So I figured, you see, now it opens choice, I can this. 479 00:43:53,240 --> 00:44:04,310 OK, guys, so we hopefully think that this is part of shooting, brings you something new and go to 480 00:44:04,310 --> 00:44:12,320 the next application but 14 and downloaded it in your folder and then we will see you there. 481 00:44:12,650 --> 00:44:13,160 All right.
