Dear Sir or Madam,

the Portmapper service (portmap, rpcbind) is required for mapping RPC
requests to a network service. The Portmapper service is needed e.g.
for mounting network shares using the Network File System (NFS).
The Portmapper service runs on port 111 tcp/udp.
In addition to being abused for DDoS reflection attacks, the
Portmapper service can be used by attackers to obtain information
on the target network like available RPC services or network shares.
Over the past months, systems responding to Portmapper requests from
anywhere on the Internet have been increasingly abused 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
Portmapper service was identified.
We would like to ask you to check this issue and take appropriate
steps to secure the Portmapper 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.

亲爱的先生或女士：，
映射RPC需要端口映射程序服务（portmap，rpcbind）
对网络服务的请求。需要端口映射器服务，例如。
用于使用网络文件系统（NFS）装载网络共享。
Portmapper服务在端口111 tcp/udp上运行。
除了被滥用进行DDoS反射攻击之外
攻击者可以使用Portmapper服务获取信息
在目标网络上，例如可用的RPC服务或网络共享。
在过去的几个月中，系统响应来自的Portmapper请求
互联网上的任何地方都被越来越多的DDoS反射所滥用
对第三方的攻击。
