1 00:00:07,050 --> 00:00:13,530 So I hope you enjoyed learning how to hack into Windows, using to reboot to special commands and for 2 00:00:13,530 --> 00:00:19,410 commands at the command line terminal, but I have something extra special as a bonus video a few students 3 00:00:19,410 --> 00:00:25,770 have asked already, well, how do we hack into a Mac or wow, I'm really glad that I use a Mac because 4 00:00:25,770 --> 00:00:27,220 the PC was so easy to hack. 5 00:00:27,600 --> 00:00:29,900 Well, I've got bad news for Mac owners as well. 6 00:00:29,910 --> 00:00:34,920 You've got just as easy a time, maybe even easier hacking into a Mac. 7 00:00:34,920 --> 00:00:42,030 You only need one reboot, one special key combination and four commands to create a new admin user 8 00:00:42,030 --> 00:00:47,070 account or to hack the route account and change the password and then log in and do anything you want 9 00:00:47,070 --> 00:00:48,500 to do on a Macintosh computer. 10 00:00:48,870 --> 00:00:53,700 So if you've got an old Mac sitting around or if you ever forget your password, it can be a little 11 00:00:53,700 --> 00:00:54,300 scary. 12 00:00:54,960 --> 00:00:59,130 But I can show you how to get back all of your files unless you've got things encrypted. 13 00:00:59,130 --> 00:01:00,860 And we'll talk about that right at the end here. 14 00:01:01,290 --> 00:01:05,010 So I've got Mac booted up here in the background. 15 00:01:05,280 --> 00:01:12,600 I'm going to use one reboot, one special key combination, and then four commands at the terminal so 16 00:01:12,600 --> 00:01:13,680 that we can get into this. 17 00:01:13,680 --> 00:01:18,960 Mac Well, I don't remember the password on this Macintosh, so I'm going to have to do a restart. 18 00:01:19,590 --> 00:01:25,770 And my first special KCM, or my one and only special key combination for Mac is going to be Command 19 00:01:25,770 --> 00:01:26,460 S. 20 00:01:27,600 --> 00:01:28,920 So as I restart. 21 00:01:31,920 --> 00:01:38,760 All right, when we reboot, we have to press the command and eskies to boot up in a single user mode, 22 00:01:39,100 --> 00:01:45,210 I've just run a simple, clear command to clear the screen on my MacBook so that you can see what we've 23 00:01:45,210 --> 00:01:45,830 got here. 24 00:01:46,140 --> 00:01:52,200 We're going to we've used our one reboot, our one special key combination with command s for single 25 00:01:52,200 --> 00:01:52,860 user mode. 26 00:01:53,130 --> 00:01:55,950 And now we're going to use these for. 27 00:01:57,030 --> 00:02:05,640 Commands Espin, FSC K Neshev Why that is going to do a filesystem check so we say Espin. 28 00:02:07,160 --> 00:02:12,890 And we can you'll notice I can do S.B and then tab the tab key will help me. 29 00:02:12,890 --> 00:02:21,380 Autofill, if you've not used that before on a Mac and then F sc k, I can just hit the tab dash f y 30 00:02:21,390 --> 00:02:22,940 so that's going to be my first command. 31 00:02:23,270 --> 00:02:25,040 You hit that and let it run. 32 00:02:25,040 --> 00:02:26,570 It will take just a little bit of time. 33 00:02:28,430 --> 00:02:34,640 That I'm going to show you, the second command has been slash mount. 34 00:02:36,050 --> 00:02:39,830 So we're going to mount the filesystem or mount the disk drive. 35 00:02:41,340 --> 00:02:52,440 Space W and their spaces between these, because we're using some flags or arguments with our Mount 36 00:02:52,440 --> 00:02:57,060 Command and you hit enter, that'll take just a little bit of time as well. 37 00:02:58,670 --> 00:03:03,980 And this next command and command is a long one, so I'm going to split it up over two lines and is 38 00:03:03,980 --> 00:03:04,670 launch. 39 00:03:05,700 --> 00:03:08,340 Seitel space lowed. 40 00:03:09,760 --> 00:03:15,250 Space and then this is a long line, so I'm going to span two lines by using the backslash here. 41 00:03:16,690 --> 00:03:25,240 I'm going to type capital or slash capital s y hit tab, and it'll fill in system than a library. 42 00:03:25,960 --> 00:03:32,050 So Capital L little capitalization matters on a Mac tab and then we need lunch. 43 00:03:32,920 --> 00:03:34,180 So lay you in. 44 00:03:34,540 --> 00:03:35,710 There's more than one lunch. 45 00:03:35,710 --> 00:03:45,640 So we do a capital D lunch Damons and then come dot Apple and we can do AP tab open. 46 00:03:46,970 --> 00:03:54,800 Open directory, Deadshot P list, if you want a really old Mac, there's a complete Apple dot directory 47 00:03:54,800 --> 00:03:56,710 services, local dot p. list. 48 00:03:57,170 --> 00:04:06,500 So if you don't get an O, P and Hattab, try Capital D, you know, directory services, local DOPs, 49 00:04:06,860 --> 00:04:10,730 Capital D, I, R and tab, and it should fill in that last piece as well. 50 00:04:11,150 --> 00:04:13,310 So we'll hit enter on that. 51 00:04:14,290 --> 00:04:18,750 Then we just need to run the password command post, W.D.. 52 00:04:19,900 --> 00:04:22,300 And it'll ask us for a new password twice. 53 00:04:28,640 --> 00:04:32,720 So I've tapped a new password and then all I have to do is type exit. 54 00:04:34,240 --> 00:04:41,290 And the Mac will reboot, well, it'll finish booting all the way into Mac OS and we'll be able to log 55 00:04:41,290 --> 00:04:43,750 in as root using our new username. 56 00:04:45,610 --> 00:04:53,320 All right, now the Mac is back to back up into the regular Mac OS, but instead of the username and 57 00:04:53,320 --> 00:04:59,500 password that I can't remember, I'm going in a root as my username and the new password that I just 58 00:04:59,500 --> 00:05:00,100 created. 59 00:05:04,400 --> 00:05:08,630 And it will ask if I want to update the key chain password, I don't want to do that because I don't 60 00:05:08,630 --> 00:05:12,110 want to mess up anything on this, Mac, and I'm not going to create a new keychain. 61 00:05:12,110 --> 00:05:15,200 I'm just going to continue my log in as the root user. 62 00:05:15,470 --> 00:05:22,000 I'm a full administrator or super user on this Macintosh computer, so I'm going to be able to create 63 00:05:22,010 --> 00:05:23,240 new user accounts. 64 00:05:23,810 --> 00:05:30,260 I'll be able to see all the user's files just like I was able to on a PC computer. 65 00:05:31,390 --> 00:05:36,540 And the first time you're on this, you may see some setting up your Mac, you may have to click through 66 00:05:36,540 --> 00:05:41,820 a couple of things, but then you'll be logged in as a user on Windows. 67 00:05:41,820 --> 00:05:49,380 If I go to my Macintosh computer, if I go to the finder and come to users, I can find my real user 68 00:05:49,380 --> 00:05:52,830 account beeping And there are all my files. 69 00:05:53,790 --> 00:06:00,180 So if I go into my documents and I see all my Udemy course files. 70 00:06:01,990 --> 00:06:07,030 I go into downloads, I'll see everything that I've downloaded recently. 71 00:06:08,570 --> 00:06:09,440 Not too bad. 72 00:06:09,710 --> 00:06:15,340 So everything is there and I'm able to get to it, and if I want to create a new user account, all 73 00:06:15,350 --> 00:06:17,930 I need to do is come to the system preferences. 74 00:06:19,980 --> 00:06:22,230 And come to users and groups. 75 00:06:25,320 --> 00:06:27,750 And if I went to, I could create a new user here. 76 00:06:29,930 --> 00:06:31,700 And give that a new name. 77 00:06:36,860 --> 00:06:39,840 You get the idea so we can create a whole new user account. 78 00:06:40,130 --> 00:06:42,710 We can either have them as a standard user, which is smart. 79 00:06:42,710 --> 00:06:45,710 You don't want to run around with a brute privileges turned on on your Mac. 80 00:06:46,430 --> 00:06:50,410 Or we can if we need to have an administrative account, we can do that as well. 81 00:06:51,520 --> 00:06:55,190 So even a Mac is not completely safe from this attack. 82 00:06:55,210 --> 00:07:03,790 In fact, we only had to use one special combination after one reboot and then four commands at the 83 00:07:03,790 --> 00:07:04,420 command line. 84 00:07:04,420 --> 00:07:06,790 And now we've got access to all of our files again. 85 00:07:07,120 --> 00:07:11,110 And we're able to to do some well, pretty cool things. 86 00:07:11,110 --> 00:07:17,650 If you own the computer, make sure you only do this on a computer that you own or have explicit written 87 00:07:17,650 --> 00:07:21,670 permission from the owner and controller to do this kind of hack. 88 00:07:22,940 --> 00:07:27,720 So one more time, just some quick lessons learned, physical access is total access. 89 00:07:28,070 --> 00:07:34,190 Never leave your laptop or desktop unattended if someone has physical access notice on the Mac, we 90 00:07:34,190 --> 00:07:35,930 didn't even have to have a boot disk. 91 00:07:35,930 --> 00:07:42,950 We just used one of the special key combinations to get in as a single user mode user so that we were 92 00:07:42,950 --> 00:07:44,510 a route user on a Mac. 93 00:07:45,470 --> 00:07:47,600 Ethical hacking is useful and practical. 94 00:07:47,600 --> 00:07:50,390 You can get to files even when you forgot in your Mac password. 95 00:07:50,960 --> 00:07:53,920 The only thing is to protect against this aquil on windows. 96 00:07:53,930 --> 00:07:56,810 We saw that we could change the settings on a Mac. 97 00:07:56,810 --> 00:08:03,680 Really, we need to use file vault or use some other encryption on your hard drive to encrypt the files 98 00:08:03,680 --> 00:08:09,320 that are either sensitive or that you just want to keep other people out of and use a strong password. 99 00:08:10,130 --> 00:08:14,360 If you're using a business laptop, you definitely need to have encryption turned on because if you 100 00:08:14,360 --> 00:08:17,300 lose access to those files, it could have customer information or more. 101 00:08:17,600 --> 00:08:22,250 If you're doing this is a home user, if you encrypt your files, the one thing you need to know is 102 00:08:22,250 --> 00:08:26,840 that if you forget that password, you cannot recover those files. 103 00:08:27,230 --> 00:08:31,670 So we have to mix our security with the usability. 104 00:08:31,670 --> 00:08:36,230 But you can see that we've got a lot of really cool things we're going to be able to do in this course. 105 00:08:36,500 --> 00:08:39,080 And we will see you in the next lesson.
