数据库中oracle 密码破解之工具

数据库中oracle 密码破解之工具

忘记了oracle密码，可以使用orapwd 初始化sys密码；然后再修改其他帐户密码，还有就是破解。

工具下载和破解速度对比见下面的连接：多数还是基于字典的破解，复杂些的密码还是比较难以破解的。推荐两个破解工具 checkpwd.exe 和 orabf.exe

2、ORABAF.EXE

首先找到用户oracle的密码的hash值38E38619A12E0257，dba_users

SQL> alter user oracle identified by oracle;

用户已更改。

SQL> select password from dba_users where username='ORACLE';

PASSWORD
------------------------------
38E38619A12E0257

SQL>

D:orabf-v0.7.6>orabf.exe

orabf v0.7.6, (C)2005 orm@toolcrypt.org
---------------------------------------

usage: orabf [hash]:[username] [options]

options:
-c [num] complexity: a number in [1..6] or a filename
- read words from stdin
[file] read words from file
1 numbers
2 alpha
3 alphanum
4 standard oracle (alpha)(alpha,num,_,#,$)... (default)
5 entire keyspace (' '..'~')
6 custom (charset read from first line of file: charset.orabf)
-m [num] max pwd len: must be in the interval [1..14] (default: 14)
-n [num] min pwd len: must be in the interval [1..14] (default: 1)
-r resume: tries to resume a previous session

D:orabf-v0.7.6>orabf.exe 38E38619A12E0257:oracle -c 6

orabf v0.7.6, (C)2005 orm@toolcrypt.org
---------------------------------------
Trying default passwords...
password found: ORACLE:ORACLE

D:orabf-v0.7.6>

修改密码后再测试

SQL> alter user oracle identified by oracle123;

用户已更改。

SQL>
SQL> select password from dba_users where username='ORACLE';

PASSWORD
------------------------------
B1BA9ED1B2B824CC

SQL>

D:orabf-v0.7.6>orabf.exe B1BA9ED1B2B824CC:oracle -c 6

orabf v0.7.6, (C)2005 orm@toolcrypt.org
---------------------------------------
Trying default passwords...
password found: ORACLE:ORACLE123

D:orabf-v0.7.6>orabf.exe B1BA9ED1B2B824CC:oracle -c 3

orabf v0.7.6, (C)2005 orm@toolcrypt.org
---------------------------------------
Trying default passwords...
password found: ORACLE:ORACLE123

D:orabf-v0.7.6>
