通過(guò)Orabrute暴力破解oracle密碼
1 標(biāo)準(zhǔn)的Oracle 密碼可以由英文字母，數(shù)字，#，下劃線(_)，美元字符($)構(gòu)成，密碼的最大長(zhǎng)度為30 字符;Oracle 密碼不能以"$"，"#"，"_"或任何數(shù)字開頭;密碼不能包含"SELECT"，"DELETE"，"CREATE"這類的Oracle/SQL 關(guān)鍵字。
2 Oracle 的弱算法加密機(jī)制：兩個(gè)相同的用戶名和密碼在兩臺(tái)不同的Oracle 數(shù)據(jù)庫(kù)機(jī)器中，將具有相同的
哈希值。這些哈希值存儲(chǔ)在SYS.USER$表中?？梢酝ㄟ^(guò)像DBA_USERS 這類的視圖來(lái)訪問(wèn)。
3 Oracle 默認(rèn)配置下，每個(gè)帳戶如果有10 次的失敗登錄，此帳戶將會(huì)被鎖定。但是SYS 帳戶在Oracle 數(shù)
據(jù)庫(kù)中具有最高權(quán)限，能夠做任何事情，包括啟動(dòng)/關(guān)閉Oracle 數(shù)據(jù)庫(kù)。即使SYS 被鎖定，也依然能夠訪問(wèn)
數(shù)據(jù)庫(kù)。
由前面的基礎(chǔ)知識(shí)3，可以得知選擇遠(yuǎn)程破解Oracle 的最好帳戶是SYS，因?yàn)榇藥粲肋h(yuǎn)有效。在Oracle10g以前的版本在安裝的時(shí)候并沒(méi)有提示修改SYS 的默認(rèn)密碼，Oracle10g 雖然提示修改密碼了，但是并沒(méi)有檢查密碼的復(fù)雜性。
可以使用Orabrute 工具來(lái)進(jìn)行遠(yuǎn)程破解，在使用這個(gè)工具的時(shí)候，需要系統(tǒng)提前安裝好Sqlplus，該工具的
原理很簡(jiǎn)單，就是不停的調(diào)用Sqlplus 然后進(jìn)行登錄驗(yàn)證，帳戶選擇的是SYS，密碼則為password.txt 中的密碼單詞。只要登錄成功，就會(huì)調(diào)用selectpassword.sql 腳本抓取出在SYS.USER$表中的其他用戶的哈希值，然后退出程序。這里有個(gè)注意的地方，當(dāng)?shù)诙芜\(yùn)行Orabrute 的時(shí)候，需要?jiǎng)h除或移動(dòng)同目錄下的前一次運(yùn)行Orabrute 時(shí)生成的thepasswordsarehere.txt 和output.txt 文件。

Orabrute 的使用方法為：

Orabrute 的破解速度比較慢，建議在password.txt開頭加上諸如change_on_install這樣你認(rèn)為可能的密碼。
