The security community raised the alarm regarding a serious issue last week —that of Android devices shipping with their debug port open to remote connections.

Vendors are shipping Android devices with open port setups that leave countless products open to attack. The port, 5555, is at the heart of an Android feature called Android Debug Bridge (ADB).

A new botnet appeared over the weekend, and it's targeting Android devices by scanning for open debug ports so it can infect victims with malware that mines the Monero cryptocurrency.

New Matryosh botnet is targeting Android systems that have left their ADB debug interface exposed on the internet.
