What is system software update android

Крайне опасное вредоносное приложение для системы Android под названием System Updates было обнаружено специалистами из компании Zimperium. Если ставить приложения только из Play Store, волноваться не о чем. Опасность подстерегает тех, кто устанавливает программы из посторонних источников. На самом деле это не обновление системы, а собирающий пользовательские данные шпион. Эти данные затем незаметно передаются на сервер злоумышленника в зашифрованном zip-файле.

Несмотря на большое количество приложений в Play Store, некоторые программы там отсутствуют. Кроме того, у пользователей может возникнуть желание перейти на более старые версии приложений, обойти блокировку по географическому признаку и другие мотивы пользоваться сторонними сайтами для установки приложений. При этом риск получить вирус настолько велик, что в Android возможность ставить приложения из-за пределов Play Store по умолчанию отключена.

Специалисты из компании Zimperium ещё раз напомнили, зачем нужны такие предосторожности. Шпионское приложение под названием System Updates показывает ложное уведомление «Поиск обновления», пока скачивает пользовательские данных на сервер злоумышленника.

Анализ вредоносного кода Zimperium показывает, что приложение не только собирает распространённую информацию, такую как данные о звонках и СМС, сообщения WhatsApp, местоположение, содержимое буфера обмена, закладки и история браузера. Здесь есть возможность контролировать устройство жертвы, записывать звук и фотографировать.

Разработчики приложения постарались свести к минимуму расход трафика, чтобы не вызывать подозрений. Выполняется сканирование документов размером менее 30 Мб и собираются миниатюры недавних изображений и видео. Они распределяются по нескольким папкам в частном хранилище приложения. Затем зашифрованный архив отправляется на сервер, а на устройстве он удаляется, чтобы замести следы.

Update system app in android

I have developed an android app and put this as prebuilt APK in AOSP. So the app will be installed in /system/app as a system app.

The app has update function itself by downloading and installing the newer version APK.

But it does not work because system app cannot be updated. Is there any way to update self-made system app?

2 Answers 2

System app can be updated, in two ways:

Updated by the ota updating, this will change the app directly, and the app still exist on /system.

updated by using package install api, this need the new version apk have the same signature with the one on /system, and the new version will be installed on /data. That means, if the device is reset, the new version will lose.

Ota update is a normal way for system app updating.

right? Is this still valid on Android 10?

Yes, you can install an updated version of your original system app into the /data partition, provided that: 1. Both app versions are signed with the same key; 2. The updated app’s versionCode is greater than or equal to the original app’s.

One way to do this update is to use the following adb command: adb install -r . Then you can test your updated version without having to rebuild your AOSP code.

Note that your updated version in the /data partition will be removed via a factory data reset. In this case your original system app will take effect again.

Опасный Android-вирус скрывается под видом обновления ОС

Среди Android-устройств начало распространяться новое вредоносное приложение под названием System Update. По словам специалистов по кибербезопасности компании Zimperium, шпионское ПО скрывается под видом системных обновлений и позволяет злоумышленникам получать полный контроль над гаджетом жертвы.

System Update нет в магазине приложений Google Play, оно загружается из сторонних источников в составе других программ. После установки вредоносное ПО скрывается и через сервер Firebase позволяет злоумышленникам удалённо управлять устройством. При этом вирус выдаёт себя за системное обновление от Google. System Update обеспечивает мошенникам доступ к микрофону и камере смартфона, а также собирает такие данные, как сообщения, контакты, информация о гаджете, закладки в браузере и история веб-сёрфинга.

Кроме того, с помощью приложения злоумышленники могут отслеживать местоположение устройства, выполнять поиск документов в памяти гаджета и записывать информацию, которая вводится пользователем с клавиатуры или копируется в буфер обмена. Чтобы не засветиться как программа, которая «ест» много трафика, System Update передаёт изображения в виде эскизов.

В Zimperium считают, что эта вредоносная утилита была частью целевой атаки и на её создание было потрачено много времени и усилий. При этом исследователи не располагают информацией о том, кто создал System Update и на кого приложение нацелено.
