Dear Sir or Madam,

NetBIOS defines a software interface and a naming convention.
NetBIOS over TCP/IP provides the NetBIOS programming interface
over the TCP/IP protocol.

Over the past months, systems responding to NetBIOS nameservice
requests from anywhere on the Internet have been increasingly
abused for DDoS reflection attacks against third parties.

Please find below a list of affected systems hosted on your network.
The timestamp (timezone UTC) indicates when the openly accessible
NetBIOS nameservice was identified.

We would like to ask you to check this issue and take appropriate
steps to secure the NetBIOS nameservices services on the affected
systems or notify your customers accordingly.

If you have recently solved the issue but received this notification
again, please note the timestamp included below. You should not
receive any further notifications with timestamps after the issue
has been solved.
