These advanced steps are primarily for system administrators and others who are familiar with the command line. You don't need a bootable installer to upgrade macOS or reinstall macOS, but it can be useful when you want to install on multiple computers without downloading the installer each time.

Download macOS

Find the appropriate download link in the upgrade instructions for each macOS version:

• macOS Catalina, macOS Mojave, and macOS High Sierra download directly to your Applications folder as an app named Install macOS Catalina, Install macOS Mojave, or Install macOS High Sierra. If the installer opens after downloading, quit it without continuing installation.
  To get the required installer, download from a Mac that is using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators, please download from Apple, not a locally hosted software-update server.
• macOS Sierra downloads as a disk image that contains a file named InstallOS.pkg. Open this file and follow the onscreen instructions. It installs an app named Install macOS Sierra into your Applications folder.
• OS X El Capitan downloads as a disk image that contains a file named InstallMacOSX.pkg. Open this file and follow the onscreen instructions. It installs an app named Install OS X El Capitan into your Applications folder.

Use the 'createinstallmedia' command in Terminal

1. Connect the USB flash drive or other volume that you're using for the bootable installer. Make sure that it has at least 12GB of available storage and is formatted as Mac OS Extended.
2. Open Terminal, which is in the Utilities folder of your Applications folder.
3. Type or paste one of the following commands in Terminal. These assume that the installer is still in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you're using. If it has a different name, replace MyVolume in these commands with the name of your volume.
   Catalina:*
   Mojave:*
   
   High Sierra:*
   Sierra:
   El Capitan:
   
4. Press Return after typing the command.
5. When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
6. When prompted, type Y to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the bootable installer is created.
7. When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Catalina. You can now quit Terminal and eject the volume.

* If your Mac is using macOS Sierra or earlier, include the --applicationpath argument, similar to the way this argument is used in the commands for Sierra and El Capitan.

Use the bootable installer

After creating the bootable installer, follow these steps to use it:

1. Plug the bootable installer into a compatible Mac.
2. Use Startup Manager or Startup Disk preferences to select the bootable installer as the startup disk, then start up from it. Your Mac will start up to macOS Recovery.
   Learn about selecting a startup disk, including what to do if your Mac doesn't start up from it.
3. Choose your language, if prompted.
4. A bootable installer doesn't download macOS from the Internet, but it does require the Internet to get information specific to your Mac model, such as firmware updates. If you need to connect to a Wi-Fi network, use the Wi-Fi menu in the menu bar.
5. Select Install macOS (or Install OS X) from the Utilities window, then click Continue and follow the onscreen instructions.

Introduction

Today, we are going to talk about the installation password of Hex-Rays IDA Pro, which is the most famous decompiler. What is installation password? Generally, customers receive a custom installer and installation password after they purchase IDA Pro. The installation password is required during installation process. However, if someday we find a leaked IDA Pro installer, is it still possible to install without an installation password? This is an interesting topic.

After brainstorming with our team members, we verified the answer: Yes! With a Linux or MacOS version installer, we can easily find the password directly. With a Windows version installer, we only need 10 minutes to calculate the password. The following is the detailed process:

* Linux and MacOS version

The first challenge is Linux and MacOS version. The installer is built with an installer creation tool called InstallBuilder. We found the plaintext installation password directly in the program memory of the running IDA Pro installer. Mission complete!

This problem is fixed after we reported through Hex-Rays. BitRock released InstallBuilder 19.2.0 with the protection of installation password on 2019/02/11.

* Windows version

It gets harder on Windows version because the installer is built with Inno Setup, which store its password with 160-bit SHA-1 hash. Therefore, we cannot get the password simply with static or dynamic analyzing the installer, and brute force is apparently not an effective way. But the situation is different if we can grasp the methodology of password generation, which lets us enumerate the password more effectively!

Although we have realized we need to find how Hex-Rays generate password, it is still really difficult, as we do not know what language the random number generator is implemented with. There are at least 88 random number generators known. It is such a great variation.

We first tried to find the charset used by random number generator. We collected all leaked installation passwords, such as hacking team’s password, which is leaked by WikiLeaks.

• FgVQyXZY2XFk (link)
• 7ChFzSbF4aik (link)
• ZFdLqEM2QMVe (link)
• 6VYGSyLguBfi (link)

From the collected passwords we can summarize the charset:
23456789ABCDEFGHJKLMPQRSTUVWXYZabcdefghijkmpqrstuvwxyz

The missing of 1, I, l, 0, O, o, N, n seems to make sense because they are confusing characters.
Next, we guess the possible charset ordering like these:

Lastly, we picked some common languages（c/php/python/perl）to implement a random number generator and enumerate all the combinations. Then we examined whether the collected passwords appears in the combinations. For example, here is a generator written in C language:

After a month, we finally generated the IDA Pro installation passwords successfully with Perl, and the correct charset ordering is abcdefghijkmpqrstuvwxyzABCDEFGHJKLMPQRSTUVWXYZ23456789. For example, we can generate the hacking team’s leaked password FgVQyXZY2XFk with the following script:

With this, we can build a dictionary of installation password, which effectively increase the efficiency of brute force attack. Generally, we can compute the password of one installer in 10 minutes.

We have reported this issue to Hex-Rays, and they promised to harden the installation password immediately.

Summary

In this article, we discussed the possibility of installing IDA Pro without owning installation password. In the end, we found plaintext password in the program memory of Linux and MacOS version. On the other hand, we determined the password generation methodology of Windows version. Therefore, we can build a dictionary to accelerate brute force attack. Finally, we can get one password at a reasonable time.

We really enjoy this process: surmise wisely and prove it with our best. It can broaden our experience no matter the result is correct or not. This is why we took a whole month to verify such a difficult surmise. We also take this attitude in our Red Team Assessment. You would love to give it a try!

Lastly, we would like to thank for the friendly and rapid response from Hex-Rays. Although this issue is not included in Security Bug Bounty Program, they still generously awarded us IDA Pro Linux and MAC version, and upgraded the Windows version for us. We really appreciate it.
