在云提供商的虚拟机中，我看到一个带有奇怪随机名称的进程。它消耗大量的网络和 CPU 资源。
从视图来看，该过程如下所示pstree：
systemd(1)───eyshcjdmzg(37775)─┬─{eyshcjdmzg}(37782)
├─{eyshcjdmzg}(37783)
└─{eyshcjdmzg}(37784)
我使用strace -p PID. 这是我得到的输出：https ://gist.github.com/gmile/eb34d262012afeea82af1c21713b1be9 。
杀死进程不起作用。它以某种方式（通过systemd？）复活了。这是从 systemd 的角度来看它的样子（注意底部奇怪的 IP 地址）：
$ systemctl status 37775

到底是怎么回事？！
