WEBVTT 1 00:00.710 --> 00:01.820 Hello and welcome. 2 00:01.820 --> 00:07.520 In this new session, we are going to start using some knowledge we have gained in our practicals. 3 00:07.880 --> 00:15.860 So we are going to try to crack the crackme as a learning experience to apply all the knowledge that 4 00:15.860 --> 00:19.880 we have acquired, and we need some additional tools for that. 5 00:19.880 --> 00:26.480 So we need to install a program called Detect It Easy, which is available from here, this website here. 6 00:26.570 --> 00:29.600 So head over to this website and download this, 7 00:29.600 --> 00:36.110 or you can use the version that I've already downloaded, and I've put it in the resource section for 8 00:36.110 --> 00:37.970 you to download and install. 9 00:38.180 --> 00:44.870 So once you have downloaded it, you go to your downloads folder, and you should be able to see the program 10 00:44.870 --> 00:46.370 in your downloads folder. 11 00:46.670 --> 00:50.240 You just need to unzip it to get the program, 12 00:50.240 --> 00:51.290 this program here. 13 00:51.500 --> 00:55.250 Then it's a standalone portable, so you can put it anywhere you want, 14 00:55.250 --> 00:58.640 and you can create a shortcut on the desktop if you want. 15 00:59.090 --> 01:08.990 So maybe you can copy this program and put it in your project folder, in your Program Files folder over 16 01:08.990 --> 01:09.500 here. 17 01:15.780 --> 01:23.130 And then go inside the program and create a shortcut on your desktop, so you can right-click this one 18 01:23.130 --> 01:25.290 and put it here. 19 01:25.290 --> 01:26.520 Create shortcut here. 20 01:26.670 --> 01:31.200 So anytime you want to run it, you just go to your desktop and double-click, and it will run. 21 01:31.710 --> 01:37.320 So this is the program that we are going to use, the additional program that we are going to use for 22 01:37.320 --> 01:39.660 doing the practicals on crackmes. 23 01:40.740 --> 01:49.080 Another thing I'd like to remind you is that we are going to use a virtual machine for all the practicals. 24 01:49.080 --> 01:56.370 So as I've already taught you in the outset of this course, you should install virtual machines running 25 01:56.370 --> 02:02.040 with your Windows 10 or Windows 11, and then do all your practicals inside the virtual machine. 26 02:02.040 --> 02:11.190 And the first thing you must do is to always make sure that you make a backup, a snapshot of all your 27 02:11.190 --> 02:14.790 virtual machines just before you start any project. 28 02:14.790 --> 02:21.000 That means if you have installed a virtual machine here, make sure before you start any project, make 29 02:21.000 --> 02:26.160 sure you click Take and then create a snapshot and save it. 30 02:26.160 --> 02:33.990 And after you have saved the snapshot and you go ahead and do your project, do your crackme or whatever you want, 31 02:33.990 --> 02:35.400 and then when you finish with the crackme, always come back and restore. 32 02:39.420 --> 02:40.560 Restore. 33 02:41.100 --> 02:46.320 That means you go back to the snapshot that you created, and then you click Restore 34 02:47.380 --> 02:47.920 right there. 35 02:47.920 --> 02:55.510 Then you will restore whatever it was in after the crackme has run. 36 02:55.780 --> 03:02.740 Now, this is important because you want to make sure that any changes made by the crackme is undone. 37 03:03.190 --> 03:07.420 Sometimes you are afraid that a crackme might be malicious, 38 03:07.420 --> 03:10.660 so you want to undo any changes made by the crackme. 39 03:10.660 --> 03:16.600 All the crackmes that are used in this course are safe, so this is harmless. 40 03:16.600 --> 03:23.320 It's just that for those who want peace of mind, then make sure you use the restore method to 41 03:23.320 --> 03:25.240 undo any changes made by the crackme. 42 03:25.990 --> 03:27.940 So that's all I want to remind you. 43 03:27.940 --> 03:29.530 Thank you for watching.
