centos netstat和ps感染木马解决方案

解决方法：

a.去除恶意文件的执行权限

chmod 000 /tmp/gates.lod /tmp/moni.lod   service sendmail stop chkconfig --level 345 sendmail off chmod -x/usr/sbin/sendmail   chmod -R 000/root/*rar* chattr -i /root/conf.n chmod -R 000 /root/conf.n*   rm -rf/usr/bin/lixww
rm -rf/usr/bin/bsd-port/getty rm -rf /tmp/gates.lock
rm -rf/tmp/moni.lock
rm -rf/usr/bin/bsd-port/getty.lock
rm -rf/usr/bin/bsd-port/conf.n

/lib/lib3.so.1 delete file

/var/opt/lm/iisdate delete上级目录

/usr/sbin/lsof ok,reinstall

/usr/bin/bsd-port/getty delete上级目录

/usr/bin/.sshd delete .sshd*

/bin/ps ok,helvetica; line-height: 18px; border: 0px; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"> /bin/netstat ok,helvetica; line-height: 18px; border: 0px; background-image: initial; background-attachment: initial; background-size: initial; background-origin: initial; background-clip: initial; background-position: initial; background-repeat: initial;"> /bin/.iptab4 delete file

强制重新安装以下软件包，覆盖被感染文件

net-tools-1.60-78.el5.i386.rpm

procps-3.2.7-11.1.el5.i386.rpm

lsof-4.78-3.i386.rpm

rpm -ivh rpm文件 --force --nodeps

升级openssl（openssl-1.0.1i）和openssh（openssh-6.6p1）到最新版本、

修改sshd端口、修改root密码为复杂字串、禁止root账号直接登录系统

通过网络交换机配置ACL禁止此服务器访问外网

以上修改完成后，重新启动系统

再次全系统扫描未发现病毒
