Accessible Apple Filesharing Protocol 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 Apple Filesharing Protocol (AFP) service on port 548/TCP.

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

These devices have the potential to leak sensitive or corporate information, such as the type of device, authentication methods accepted, internal IP address(es), server name (machine and trivial), and the DirectoryService that it uses.

Servers that are exposing this information 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 548/tcp with "GetStatus" request 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 AFP enabled, try the nmap command: "nmap -v -p 548 [IP]"

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.
