Установка Кали Линукс Live USB

Когда нужно аккуратно проверить систему и оставить жесткий диск нетронутым, выручит Kali Linux Live USB. Но у него есть один недостаток – некуда сохранять найденную информацию. К счастью, возможна установка Kali Linux Live USB на носитель с сохранением данных на нем же.

Установка Kali Linux Live USB

Для хранения данных потребуется создать не только Kali Linux Live USB, но и дополнительный раздел под данные (найденный password, например).

Как скачать дистрибутив

Для создания Kali Linux Live USB потребуется загрузить образ со страницы загрузок на официальном ресурсе https://www.kali.org.

Образы для установки Kali Linux Live USB можно сохранить напрямую с сайта по http-ссылке или использовать торрент.

Запись носителя

Если бы требовалось создать Live CD Kali Linux, то скачанный ISO файл было бы достаточно прожечь на диск. Для USB потребуется специальная утилита – например, можно взять WinSetupFromUSB.

В главном окне нужно выбрать носитель для установки, подключить автоформатирование и затем в поле Linux ISO открыть загруженный образ.

Внимание! Лучше использовать накопитель от 8 ГБ – сам полный образ занимает порядке 3 ГБ, так что при меньшем размере места под раздел с сохранением данных остается совсем мало.

Если отметить пункт «Test in QEMU», то после записи утилита проведет тестирование на возможность загрузки и установки.

Перед записью программа предупредит о стирании данных.

Затем будет показана информация по форматированию.

Затем образ установки будет записан.

При отмеченном тесте появится окно эмулятора со стартовым меню. Но пока еще флешка не умеет работать с сохранением данных.

Добавление раздела с сохранением данных

Дальнейшие действия выполняются уже из самого Линукса (можно загрузиться из полной установки или с Лайв-версии). Для работы с разделами используем утилиту gparted, запустив ее из командной строки.

Откроется основное окно программы. Нужно в выпадающем списке справа выбрать Kali Linux Live USB.

Откроется просмотр структуры разделов. Чтобы можно было работать с Kali Linux Live USB, следует размонтировать раздел.

Теперь нужно сжать его через соответствующую команду в меню «Раздел».

Откроется окно с установкой параметров.

Нужно указать новый размер раздела. Свободное место пересчитывается автоматически.

Затем на освободившемся месте нужно создать раздел, с которым Kali будет работать с сохранением данных.

Следует выбрать файловую систему ext4, в качестве метки прописать persistence и нажать «Добавить».

В результате получится примерно такая структура Kali Linux Live USB.

Теперь нужно применить все установки через меню Правка.

Приложение предупредит о возможном риске.

Затем операции будут выполнены.

Теперь нужно создать в разделе с сохранением данных конфигурационный файл. Для этого открываем диспетчер файлов.

И затем кликаем по разделу Kali Linux Live USB, чтобы он примонтировался.

Запустим текстовый редактор и в новом документе напишем «/ union» (чтобы использовать с сохранением данных).

После этого его нужно сохранить с именем persistence.conf на созданном разделе с сохранением данных.

Если его открыть, будет виден файл.

При загрузке с Kali Linux Live USB нужно будет выбрать пункт Live USB Persistence. Пароль для раздела не требуется.

Kali linux live usb boot

Our favourite way, and the fastest method, for getting up and running with Kali Linux is to run it “live” from a USB drive. This method has several advantages:

• It’s non-destructive — it makes no changes to the host system’s hard drive or installed OS, and to go back to normal operations, you simply remove the “Kali Live” USB drive and restart the system.
• It’s portable — you can carry Kali Linux in your pocket and have it running in minutes on an available system
• It’s customizable — you can roll your own custom Kali Linux ISO image and put it onto a USB drive using the same procedures
• It’s potentially persistent — with a bit of extra effort, you can configure your Kali Linux “live” USB drive to have persistent storage, so the data you collect is saved across reboots

In order to do this, we first need to create a bootable USB drive which has been set up from an ISO image of Kali Linux.

What You’ll Need

A verified copy of the appropriate ISO image of the latest Kali build image for the system you’ll be running it on: see the details on downloading official Kali Linux images.

If you’re running under Linux, you can use the dd command, which is pre-installed, or use Etcher.

A USB thumb drive, 4GB or larger. (Systems with a direct SD card slot can use an SD card with similar capacity. The procedure is identical.)

Kali Linux Live USB Install Procedure

The specifics of this procedure will vary depending on whether you’re doing it on a Windows, Linux, or macOS/OS X system.

Creating a Bootable Kali USB Drive on Linux (DD)

Creating a bootable Kali Linux USB drive in a Linux environment is easy. Once you’ve downloaded and verified your Kali ISO file, you can use the dd command to copy it over to your USB drive using the following procedure. Note that you’ll need to be running as root, or to execute the dd command with sudo. The following example assumes a Linux Mint 17.1 desktop — depending on the distro you’re using, a few specifics may vary slightly, but the general idea should be very similar. If you would prefer to use Etcher, then follow the same directions as a Windows user. Note that the USB drive will have a path similar to /dev/sdb.

WARNING: Although the process of imaging Kali Linux onto a USB drive is very easy, you can just as easily overwrite a disk drive you didn’t intend to with dd if you do not understand what you are doing, or if you specify an incorrect output path. Double-check what you’re doing before you do it, it’ll be too late afterwards.

Consider yourself warned.

1. First, you’ll need to identify the device path to use to write the image to your USB drive. Without the USB drive inserted into a port, execute the command sudo fdisk -l at a command prompt in a terminal window (if you don’t use elevated privileges with fdisk, you won’t get any output). You’ll get output that will look something (not exactly) like this, showing a single drive — “/dev/sda” — containing three partitions (/dev/sda1, /dev/sda2, and /dev/sda5):

2. Now, plug your USB drive into an available USB port on your system, and run the same command, “sudo fdisk -l” a second time. Now, the output will look something (again, not exactly) like this, showing an additional device which wasn’t there previously, in this example “/dev/sdb”, a 16GB USB drive:

3. Proceed to (carefully!) image the Kali ISO file on the USB device. The example command below assumes that the ISO image you’re writing is named “kali-linux-2021.3-live-amd64.iso” and is in your current working directory. The blocksize parameter can be increased, and while it may speed up the operation of the dd command, it can occasionally produce unbootable USB drives, depending on your system and a lot of different factors. The recommended value, “bs=4M”, is conservative and reliable.

Imaging the USB drive can take a good amount of time, over ten minutes or more is not unusual, as the sample output below shows. Be patient!

The dd command provides no feedback until it’s completed, but if your drive has an access indicator, you’ll probably see it flickering from time to time. The time to dd the image across will depend on the speed of the system used, USB drive itself, and USB port it’s inserted into. Once dd has finished imaging the drive, it will output something that looks like this:

That’s it, really!

Creating a Bootable Kali USB Drive on Linux (DD with status)

Alternatively there are a few other options available for imaging.

The first option is dd with a status indicator. This is only available on newer systems however. To do this, we simply add the status flag.

Another option is to use pv . We can also use the size flag here to get an approximate timer. Change the size depending on the image being used.

Creating a Bootable Kali USB Drive on Linux (Etcher)

Download and run Etcher.

Choose the Kali Linux ISO file to be imaged with “select image” and verify that the USB drive to be overwritten is the correct one. Click the “Flash!” button once ready.

3. Once Etcher alerts you that the image has been flashed, you can safely remove the USB drive.

You can now boot into a Kali Live / Installer environment using the USB device.

Kali linux live usb boot

Kali Linux “Live” has two options in the default boot menu which enable persistence — the preservation of data on the “Kali Live” USB drive — across reboots of “Kali Live”. This can be an extremely useful enhancement, and enables you to retain documents, collected testing results, configurations, etc., when running Kali Linux “Live” from the USB drive, even across different systems. The persistent data is stored in its own partition on the USB drive, which can also be optionally LUKS-encrypted.

To make use of the USB persistence options at boot time, you’ll need to do some additional setup on your “Kali Linux Live” USB drive; this article will show you how.

This guide assumes that you have already created a Kali Linux “Live” USB drive as described in the doc page for that subject. For the purposes of this article, we’ll assume you’re working on a Linux-based system.

You’ll need to have root privileges to do this procedure, or the ability to escalate your privileges with the command “sudo su”.

In this example, we assume:

• you are running as the root user. As of Kali Linux 2020.1, we do not use root user by default. You can switch to root using the command “sudo bash”
• your USB drive is /dev/sdb
• your USB drive has a capacity of at least 8GB — the Kali Linux image takes over 3GB, and for this guide, we’ll be creating a new partition of about 4GB to store our persistent data in
• you are running on a separate Linux system (cannot be Live Boot Kali)

In this example, we’ll create a new partition to store our persistent data into, starting right above the second Kali Live partition and ending at 7GB, put an ext3 file system onto it, and create a persistence.conf file on the new partition.

First, begin by imaging the latest Kali Linux ISO (currently 2021.3) to your USB drive as described in this article. We’re going to assume that the two partitions created by the imaging are /dev/sdb1 and /dev/sdb2 . This can be verified with the command fdisk -l .

Create and format an additional partition on the USB drive. First, let’s create the new partition in the empty space above our Kali Live partitions. We have to do this from the command line as gparted will read the imaged ISO as a large block. The following command will, as a short explanation, shrink that block to only be the Kali Live partition.

The parted command may advise you that it can’t use the exact start values you specified; if so, accept the suggested value instead. If advised that the partition isn’t placed at an optimal location, “ignore” it. When parted completes, the new partition should have been created at /dev/sdb3 ; again, this can be verified with the command fdisk -l .

1. Next, create an ext3 file system in the partition and label it persistence .

1. Create a mount point, mount the new partition there, and then create the configuration file to enable persistence. Finally, unmount the partition.

Adding USB Persistence with LUKS Encryption

Alternatively, you can create a LUKS-encrypted persistent storage area. This adds an extra layer of security to your sensitive files when traveling with Kali Live on USB devices. In the following example, we’ll create a new partition to store our persistent data into, starting right above the second Kali Live partition and ending at 7GB, set up LUKS encryption on the new partition, put an ext3 file system onto it, and create a persistence.conf file on it.

1. Image the latest Kali Linux ISO (currently 2021.3) to your USB drive as described in this article.
2. Create the new partition in the empty space above our Kali Live partitions.

The parted command may advise you that it can’t use the exact start value you specified; if so, accept the suggested value instead. If advised that the partition isn’t placed at an optimal location, “ignore” it. When parted completes, the new partition should have been created at /dev/sdb3 ; again, this can be verified with the command fdisk -l .

1. Initialize the LUKS encryption on the newly-created partition. You’ll be warned that this will overwrite any data on the partition. When prompted whether you want to proceed, type “YES” (all upper case). Enter your selected passphrase twice when asked to do so, and be sure to pick a passphrase you’re going to remember: if you forget it, your data will still be persistent, just irretrievable (and unusable).

1. Create the ext3 filesystem, and label it “persistence”.

1. Create a mount point, mount our new encrypted partition there, set up the persistence.conf file, and unmount the partition.

1. Close the encrypted channel to our persistence partition.

That’s really all there is to it! To use the persistent data features, simply plug your USB drive into the computer you want to boot up Kali Live on — make sure your BIOS is set to boot from your USB device — and fire it up. When the Kali Linux boot screen is displayed, choose the persistent option you set up on your USB drive, either normal or encrypted.
