WEBVTT 00:00.150 --> 00:06.570 So in APK studio, which is a cross platform idea for reverse engineering and recompiling of Android 00:06.570 --> 00:15.330 application binaries within a single user interface, we will install a studio on the host machine. 00:16.720 --> 00:22.840 All right, so here we'll use the APK lab extension for the same purposes, but we would like to show 00:22.840 --> 00:29.320 the installation and usage of a studio for those who want to use a studio. 00:30.130 --> 00:36.140 Of course, if you don't want to install a bookcase studio, please just go ahead and skip the lecture. 00:36.340 --> 00:38.520 You won't be penalized, I promise. 00:39.890 --> 00:45.230 So, you know, the drill over the browser, search for a studio, click on GitHub page. 00:46.340 --> 00:50.000 Now, scroll down a bit, and this is the user interface. 00:51.610 --> 00:56.890 So we can download it from the releases page, but first, let's look at some information. 00:57.810 --> 01:02.400 So that we know how to build it and all of that information is right here on the wiki page. 01:03.910 --> 01:06.040 So we first need to install Kutty. 01:07.600 --> 01:08.620 So open the page. 01:10.780 --> 01:15.070 And these are the packages and installers of Kutty five. 01:16.260 --> 01:20.130 You can download an offline installer to install easily. 01:22.310 --> 01:24.880 Download one of the installers, depending on your host system. 01:26.030 --> 01:34.010 And I've already got it, so I'll download it via homebrew on my Mac OS, so that means on the terminal 01:34.010 --> 01:34.460 screen. 01:35.980 --> 01:37.570 First run Broo update. 01:38.510 --> 01:40.130 And it's already up to date. 01:41.320 --> 01:45.550 Mine is yours might not be, but I just want to make sure that we're all on the same page. 01:47.510 --> 01:50.240 So we'll run Broo, install Kutty. 01:53.020 --> 01:55.410 And you can see it's already installed on my host machine. 01:56.790 --> 01:59.280 So let's visit the releases page. 02:03.530 --> 02:06.440 I'll install the latest disk image for Mac OS. 02:07.550 --> 02:10.820 Of course, if you're using windows, just install the zip file. 02:12.310 --> 02:13.300 Save the file. 02:13.560 --> 02:16.300 OK, and we can wait for a bit. 02:17.680 --> 02:20.020 All right, so now that is downloaded, let's open it. 02:23.700 --> 02:25.140 What is this? 02:25.170 --> 02:29.250 There seems to be a problem with the icon of a studio. 02:30.420 --> 02:31.140 It's not important. 02:32.400 --> 02:34.530 Well, drag it to the applications folder. 02:36.830 --> 02:41.540 OK, so if you're still here, let's open it from the applications folder. 02:42.580 --> 02:49.390 Don't you know what McCoist needs to trust this application, not a bad idea, so, all right, quick 02:49.780 --> 02:50.740 and open. 02:52.650 --> 02:56.790 OK, so now we need to install the missing tool so that we can use a studio. 02:58.290 --> 03:08.250 So let's look at the necessary tools and settings, so we need Apaid tool, Jadakiss, HDB and APK Sinar. 03:09.510 --> 03:13.980 So really, all we have to do is write the location of their binary files here. 03:15.420 --> 03:17.790 So to download Java, let's click on this link. 03:19.380 --> 03:24.120 You can download Java from this website and click on JDK download. 03:26.470 --> 03:28.000 You'll have to scroll down a bit. 03:29.350 --> 03:32.340 And then download one of the packages, depending on your host machine. 03:33.700 --> 03:36.920 Of course, I will select the one for macher was. 03:38.490 --> 03:40.620 Accept the agreement and download. 03:46.190 --> 03:49.280 All right, so it's downloaded so I can click on it. 03:54.710 --> 03:56.270 And double click on the package. 03:58.470 --> 04:02.700 Continue, install and enter the password or fingerprint. 04:05.110 --> 04:08.920 OK, close it up now, let's go back to the settings. 04:13.000 --> 04:18.550 So next, we need to install a RPK tool for the host machine to be able to run a big studio. 04:19.670 --> 04:23.060 We'll need to download it on the county machine later. 04:24.330 --> 04:25.710 So click on this link. 04:26.910 --> 04:28.260 Download the jar file. 04:34.600 --> 04:43.360 All right, so let's go to the downloads folder and we'll give the location of this file to Apex Studio. 04:44.880 --> 04:51.210 Of course, you can put binary files wherever you want, but I'll create a folder and collect it so 04:51.210 --> 04:52.860 that I can just keep it all together. 04:53.190 --> 04:55.440 I do like being organized. 04:56.930 --> 05:04.430 So I created a folder called Binaries under the documents folder, and I'll move the RPK tool here. 05:05.060 --> 05:12.740 OK, so let's add the location of the tool jar file to a bookcase, studio settings. 05:13.010 --> 05:15.590 So just click on browse and select the file. 05:17.990 --> 05:24.410 OK, so the next necessary tool is Genex, so click on this link to download. 05:25.570 --> 05:28.300 Download genetics from the first link. 05:29.650 --> 05:33.220 OK, so let's open it up by unzipping. 05:36.150 --> 05:40.250 So the executable file of Jadakiss is under the bin folder. 05:41.790 --> 05:44.420 Also, move the jet folder to the binaries folder. 05:46.510 --> 05:51.280 OK, so let's add the location of genetics to a studio settings. 05:52.450 --> 05:54.280 Click on Browse Select File. 05:58.700 --> 06:01.910 All right, so the next one is EDB. 06:03.220 --> 06:07.240 Now, we don't need to download EDB because it comes with Android studio. 06:08.680 --> 06:18.400 But we do need to know where EDB is, sort of learn this, just open up Android studio and click configure. 06:19.480 --> 06:21.340 And Open SDK manager. 06:23.110 --> 06:27.520 And here we've got the STK location, so Copiah. 06:29.250 --> 06:35.110 Now, go to this location from the file manager, or you can always use a terminal if you want. 06:35.790 --> 06:37.440 I'm going to continue with the terminal. 06:39.030 --> 06:43.200 So we'll change the directory to this location list files. 06:45.680 --> 06:48.290 So now let's look at the platform tools folder. 06:50.430 --> 06:51.630 And it's here. 06:52.900 --> 06:56.170 So run TWD to copy their current location. 06:58.120 --> 07:01.960 Paste it here and don't forget to add the EDB. 07:04.510 --> 07:06.380 All right, we're almost there. 07:07.270 --> 07:08.350 So finally. 07:09.470 --> 07:13.200 We've got to have the Uber app case to. 07:13.230 --> 07:15.890 All right, so let's click on this link. 07:17.780 --> 07:19.130 Download the jar file. 07:22.000 --> 07:23.410 Go to the downloads folder. 07:26.270 --> 07:30.400 And I am going to move this file to the binaries folder as well. 07:32.650 --> 07:34.060 So now go back. 07:35.120 --> 07:38.180 Click on Browse and select the file. 07:40.880 --> 07:45.440 All right, so that is a process and we've now completed. 07:47.070 --> 07:51.570 Installing the necessary tools, let me just see. 07:51.590 --> 07:58.830 Yeah, so let's do this will restart a studio and we're going to check through all the tools. 08:00.240 --> 08:03.900 All right, so here you can see all of the versions of each tool. 08:05.130 --> 08:08.610 And that means there is no problem, we have done it. 08:09.480 --> 08:10.840 So that's some good work. 08:11.610 --> 08:15.870 Let's add an epic fail here and check if epic studio works. 08:17.140 --> 08:23.050 So we're going to use the insecure bank application for testing, so we might as well download it. 08:24.480 --> 08:27.030 Search for in your bank, the two. 08:28.760 --> 08:30.710 And just click on the GitHub page. 08:31.670 --> 08:34.880 Go to the releases page and download the APK file. 08:37.650 --> 08:48.360 Now, let's the this file in a studio, so if you look under the file tab, click on Open and APK. 08:49.980 --> 08:59.780 Selecta apk file and open it, select the decompiled Java option and click on the decompiled button. 09:01.310 --> 09:06.460 All right, so it's compiling might take a moment or two. 09:08.400 --> 09:09.350 Wait for it. 09:10.940 --> 09:15.110 All right, so here is the decompiled source code of APIC. 09:16.520 --> 09:20.910 Of course, we're going to analyze it in great detail while we're testing.
