**Android Debug Bridge** (adb) is a versatile command-line tool that lets you communicate with a device. The adb command facilitates a variety of device actions, such as i**nstalling and debugging apps**, and it provides **access to a Unix shell** that you can use to run a variety of commands on a device. (from [here](https://developer.android.com/studio/command-line/adb))
In order to completely download the data of an application you can:
```bash
# From a root console
chmod 777 /data/data/com.package
cp -r /data/data/com.package /sdcard Note: Using ADB attacker cannot obtain data directly by using command " adb pull /data/data/com.package". He is compulsorily required to move data to Internal storage and then he can pull that data.
adb pull "/sdcard/com.package"
```
You can use this trick to **retrieve sensitive information like chrome passwords**. For more info about this check the information a references provided [**here**](https://github.com/carlospolop/hacktricks/issues/274).
