Как скачать и установить Кали Линукс на Андроид

Если хочется проверить ближайшее IT окружение на прочность, а под рукой только смартфон, пригодится Kali Linux для Android. Вот только установка на мобильное устройство имеет свои нюансы. Давайте рассмотрим, как поставить популярный хакерский дистрибутив на Android.

Как скачать и установить Kali Linux на Android

Есть два варианта: поддерживается модель устройства на Андроид разработчиками или же нет. Установка Kali будет сильно отличаться.

Как установить для поддерживающихся устройств

• на Андроиде активирован root;
• поставлен TWRP (скачать из магазина https://play.google.com/store/apps/details?id=me.twrp.twrpapp);
• сделан бэкап (желательно).

Доступные варианты специального дистрибутива Kali Linux Android под названием NetHunter представлены на странице https://www.offensive-security.com/kali-linux-nethunter-download/ . Их не так много – для линейки Nexus и для OnePlus One.

У совпадающего по модели и версии ОС варианта нужно кликнуть по ZIP (прямая загрузка) или Trnt (скачивание через торрент). Во втором случае потребуется torrent клиент вроде доступного на https://www.utorrent.com/ μTorrent. Скачанный файл необходимо открыть в клиенте (например, через меню Файл) и указать место для сохранения.

Начнется процесс скачивания Kali Линукс (на русском).

После завершения нужно скопировать архив SD карту или внутренний накопитель устройства и прошить его через TWRP (в режиме recovery). Детальную информацию на русском по этой программе можно найти на 4pda.ru, там же есть инструкции для различных аппаратов.

Также советуем узнать как скачать образ Кали Линукс ISO. А если вы являетесь владельцем Samsung Galaxy S4 mini и не знаете как установить Кали Линукс, тогда вам сюда.

Если устройства нет в списке

Куда интересней рассмотреть вариант универсальный, который подойдет практически для любого смартфона на Android. Тут тоже потребуются дополнительные приложения – Linux Deploy (не работает без рут) и VNC Viewer. Можно скачать из Google Play.

Сначала потребуется Linux Deploy. Обратите внимание на адрес в заголовке, он еще потребуется, чтобы все заработало.

Надо перейти в настройки (иконка с ползунками) и выбрать Kali Linux в разделе «Дистрибутив».

Затем прокрутить параметры настройки будущего Kali Linux Android вниз и поставить галочки возле SSH и графики, чтобы VNC могла к нему подключаться.

Если потребуется, можно переключить архитектуру, но обычно программа сама корректно выставляет остальные настройки для распаковки на Андроид. Также запишите логин и пароль для входа в Linux. Далее нужно установить дистрибутив на Android. Для этого на главной странице приложения следует нажать «Установить» в выпадающем меню.

Во всплывающем окне нужно согласиться.

Дальше требуется подождать: системе нужно скачать все пакеты для Kali Linux Android.

Указанием на завершение установки будет надпись

Появится еще одно предупреждение.

После завершения можно нажать Start – это запустит дистрибутив Kali в программном контейнере на Android.

Запуск Kali Линукс Android обычно происходит быстрее установки.

После этого нужно перейти в VNC Viewer. Если приложение на смартфоне Android включается впервые, появится приветственная страница.

После них откроется основное окно. Подключение к Kali Linux добавляется нажатием на плюс.

Потребуется ввести тот самый адрес из Linux Deploy, а также имя, чтобы находить подключение в адресной книге на Андроид.

Выглядит это так.

Чтобы увидеть Kali Linux, нужно нажать на подключение и затем на Connect.

Если VNC спросит пароль для подключения, надо указать changeme. Логин и пароль для установленного на Android дистрибутива Kali можно найти в настройках Linux Deploy.

Наконец, откроется рабочий стол Kali Linux Android.

Kali Linux on Android using Linux Deploy

Kali Linux on any Android Phone or Tablet

Getting Kali Linux to run on ARM hardware has been a major goal for us since day one. So far, we’ve built native images for the Samsung Chromebook, Odroid U2, Raspberry Pi, RK3306, Galaxy Note 10.1, CuBox, Efika MX, and BeagleBone Black to name a few. This however does not mean you cannot install Kali Linux in a chroot on almost any modern device that runs Android. In fact, the developers of Linux Deploy have made it extremely easy to get any number of Linux distributions installed in a chroot environment using a simple GUI builder.

Prerequisites

• A device running Android 2.1 and above, rooted.
• At least 5 GB free space on internal or external storage.
• A fast, wireless internet connection.
• Patience to wait for a distribution to bootstrap from the network.

Configuring Linux Deploy for Kali

There’s actually very little to be done to get Kali installed. By choosing Kali Linux in the “Distribution” tab, you’ve pretty much covered the important stuff. Optionally, you can choose your architecture, verify that the Kali mirror is correct, set your installation type and location on your Android device, etc. Generally speaking, the defaults provided by Linux Deploy are good to begin with.

Building the Kali Image

Once you are happy with all the settings, hitting the “install” button will start a Kali Linux bootstrap directly from our repositories. Depending on your Internet connection speed, this process could take a while. You’ll be downloading a base install of Kali Linux (with no tools) at minimum.

Starting up your chrooted Kali

Once the installation is complete, you can have Linux Deploy automatically mount and load up your Kali Linux chroot image. This also includes the starting of services such as SSH and VNC for easier remote access. All of this is automagically done by hitting the “start” button. You should see Linux Deploy setting up your image with output similar to the following:

At this stage, Linux Deploy has started a VNC and SSH server inside your chrooted Kali image. You can connect to the Kali session remotely using the IP address assigned to your Android device (in my case, 10.0.0.10).

Logging in to your chrooted Kali

Now you can use either a SSH or VNC client to access your Kali instance. The VNC password is “changeme” and the SSH credentials are “android” for the username (configured via Linux Deploy) and “changeme” as the password.

Image Size Considerations

If left unchanged, Linux Deploy will automatically set an image size of around 4 GB, for a “naked” installation of Kali. If you would like to install additional Kali tools down the road, you might want to consider using a larger image size, which is configurable via the settings in Linux Deploy.

Local VNC Connections

We had to try a couple of VNC clients to get one to work properly. Although controlling Kali through a local VNC client isn’t the most convenient of tasks, it certainly is possible. However, we suspect that most people will be SSH’ing into this instance. The picture below was overlayed with a Kali Linux desktop screenshot taken from a Galaxy S4.

Anyone fancy a simple smartphone hardware backdoor?

Overview

Kali NetHunter is available for un-rooted devices (NetHunter Rootless), for rooted devices that have a custom recovery (NetHunter Lite), and for rooted devices with custom recovery for which a NetHunter specific kernel is available (NetHunter).

The core of Kali NetHunter, which is included in all three editions, comprises of:

Kali Linux container that includes all the tools and applications that Kali Linux provides

Kali NetHunter App Store with dozens of purpose-built security apps

Android client to access the Kali NetHunter App Store

Kali NetHunter Desktop Experience (KeX) to run full Kali Linux desktop sessions with support for screen mirroring via HDMI or wireless screen casting
