數據庫中oracle 密碼破解之工具篇
忘記了oracle密碼，可以使用orapwd 初始化sys密碼；然后再修改其他帳戶(hù)密碼，還有就是破解。
工具下載和破解速度對比見(jiàn)下面的連接：多數還是基于字典的破解，復雜些的密碼還是比較難以破解的。推薦兩個(gè)破解工具 checkpwd.exe 和 orabf.exe

2、ORABAF.EXE
首先找到用戶(hù)oracle的密碼的hash值38E38619A12E0257，dba_users
SQL> alter user oracle identified by oracle;
用戶(hù)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>
修改密碼后再測試
SQL> alter user oracle identified by oracle123;
用戶(hù)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
