Does the latest Android release is secure against the ADB vulnerabiliy?

Question

I have two smartphones running Android 10 and 8, The ADB is enabled for many proposes. Generally some vendors have been shipping products with Android Debug Bridge enabled. But it seems that enabling ADB have many security risks according to DoublePpulsar blog: Root Bridge — how thousands of internet connected Android devices now have no security, and are being exploited by criminals.



This is highly problematic as it allows anybody — without any password — to remotely access these devices as ‘root’* — the administrator mode — and then silently install software and execute malicious functions.

Answer

Sorry but it seems Kevin Beaumont from Microsoft has no clue what he is talking about. Mythbusters would proof him wrong..



It is completely unauthenticated, meaning anybody can connect to a device



That is simply not true. Even on rooted android TV boxes (where the adb miner supposed to run) one still must have access to home network (which is not possible through NAT/Firewall)


Furthermore it requires at least one initial authorization of the RSA-Key from the host which is trying to connect - user must explicitly confirm this on tv screen with remote control (android tv box)


the analysis is based on open port scan where ~ 5000 devices in asia found open port 5555. But just open port means nothing. At least, according Hui Wang these adb miner did not succeed at all
