sqlpus 一个简单的登录+退出使用了22秒,严重的慢,通过strace分析发现访问以下两个ip,但是10.11.0.41非常慢,10.13.0.41很快,并且通过一些信息53端口,判断可能是dns服务器的ip

connect(9, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("10.13.0.41")}, 16) = 0

connect(12, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("10.11.0.41")}, 16) = 0

进一步确认,确认是该服务器配置的dns服务器

[root@xifenfei ~]# cat /etc/resolv.conf
# Generated by NetworkManager
nameserver 10.13.0.41
nameserver 10.11.0.41

对这两个ip的连通性进行测试

[root@xifenfei ~]# ping 10.13.0.41
PING 10.13.0.41 (10.13.0.41) 56(84) bytes of data.
64 bytes from 10.13.0.41: icmp_seq=1 ttl=126 time=0.616 ms

rtt min/avg/max/mdev = 0.616/0.616/0.616/0.000 ms

[root@xifenfei ~]# 

确认10.11.0.41 ip不通,对于此类问题最快的解决方案就是除掉不可使用的dns服务器,然后测试登录和退出时间

通过除掉不可用的dns服务器ip之后,测试时间为1s,恢复正常

最近几种勒索病毒加密数据库可完美恢复

最近有一些朋友咨询了几种oracle数据库被加密的勒索病毒,我们都可以通过工具修复实现数据库直接open,数据使用exp/expdp导出,实现数据近似完美恢复,业务直接测试正常,远比各种工具直接导出数据效果要好很多.比如以下几种:
.id[A6B00388-2930].[Ransomwaree2020@cock.li].eking
20211026231753


.id[BCD26C0D-3009].[decrypt20@firemail.cc].eking
20211026232009

.hospitalhelper.17E-D66-320
20211026232144

对于类似这些病毒,我们可以通过工具修复实现数据库直接open
20211026231633

如果此类的数据库(oracle,mysql,sql server)等被加密,需要专业恢复技术支持,请联系我们:
