The Shadowserver Foundation

Accessible Android Debug Bridge Scanning Project

If you are looking at this page, then more than likely, you noticed a scan coming from this server across your network and/or poking at the Android Debug Bridge (ADB) service.

The Shadowserver Foundation is currently undertaking a project to search for publicly accessible devices that have the ADB service running. The goal of this project is to identify openly accessible systems that have the ADB service running and report them back to the network owners for remediation.

In addition to disclosing potentially sensitive information, these devices have the potential to be compromised and added to miscreant botnets. If at all possible, we would like to see these services made un-available to miscreants that would misuse these resources.

Devices that are configured this way have been incorporated into our reports and are being reported on a daily basis.

Methodology

We are querying all computers with routable IPv4 addresses that are not firewalled from the internet on port 5555/tcp with an "adb connect" command and capturing the response. We intend no harm, but if we are causing problems, please contact us at: dnsscan [at] shadowserver [dot] org.

If you would like to test your own device to see if it has ADB enabled, try using the Android Developer tools and executing the command "adb connect [IP]". If the connection is successful, the command "adb devices" will list the IP you connected to

Blocklisting

To be removed from this set of scanning you will need to send an email to dnsscan [at] shadowserver [dot] org with the specific CIDR's that you would like to have removed. You will have to be the verifiable owner of these CIDR's and be able to prove that fact.
