Disable ADB backup to prevent unauthorized data extraction
<manifest ...>
<application
android:name=".MyApplication"
android:allowBackup="true"
android:label="@string/app_name"
android:theme="@style/AppTheme">
</application>
</manifest>
In this AndroidManifest.xml configuration, the
android:allowBackup
attribute
is either set to
true
or is missing, which defaults to
true
. This means
that Android's ADB backup feature is enabled, allowing users (or attackers)
with ADB access to extract app data, including sensitive user information.
This vulnerability can be exploited if a device is compromised or if an attacker
gains temporary access to a user's unlocked device, allowing them to execute
adb backup
commands to retrieve application data.
To mitigate this risk, the
android:allowBackup
attribute should be explicitly
set to
false
in the AndroidManifest.xml file.
<manifest ...>
<application
android:name=".MyApplication"
android:allowBackup="false"
android:label="@string/app_name"
android:theme="@style/AppTheme">
</application>
</manifest>
This corrected AndroidManifest.xml configuration explicitly sets the
android:allowBackup
attribute to
false
, preventing the application from being
backed up using ADB.
By disabling ADB backup, attackers cannot extract sensitive application data,
reducing the risk of data theft in case of unauthorized access to the device.
It is recommended to apply this configuration to all applications that handle
sensitive user data.
