The Android Debug Bridge (adb) is a command-line tool that allows developers to communicate with an Android device. The adb command facilitates a variety of device actions, such as installing and debugging apps, and it provides access to a Unix shell that you can use to run a variety of commands on a device.
The ADB could be abused by malware to target Android phones through the port 5555. By default, Android has Android Debug Bridge (ADB) option disabled, but often vendors enable it to customize the operating system, then ship the devices with the feature turned on. In September 2018, researchers observed the Hide and Seek (HNS) IoT botnet targeting Android devices with ADB option enabled.
In June, Trend Micro discovered an Android crypto-currency mining botnet that can spread via open ADB (Android Debug Bridge) ports and Secure Shell (SSH).

The bot scans the web for unsecured devices exposing the debug post, then operators download a version of the Ares malware on the device, that start scanning the web for other systems to infect.
Ares bot also scans for both other Android systems running Telnet services and attempt to crack passwords protecting them.
“The Ares bot can copy and write itself to other targeted Android IoT devices running with exposed ADB services. Launching Password Cracking Telnet Scans and Infecting Devices: After the execution of
The Ares bot is camouflaged and distributed as an
As a result, any infected Android devices, especially those installed in enterprise environments, can become points of entry in a breach. Companies are advised to implement firewalls or other security solutions, or segment local networks, so any infected device doesn’t have access to critical systems.
