警告：互联网中有oracle介质被注入恶意程序导致—ORA-600 16703

发表于 2017 年 7 月 11 日由惜分飞

继续上篇的tab$被清空(ORA-600 16703故障解析—tab$表被清空),导致数据库启动异常的case
ORA-600 16703报错

数据库日志分析
数据库open成功同时报ORA-7445 kokeicbegin和ORA-600 kzrini:!uprofile错误

再次启动数据库直接报ORA-600 16703错误

这里有一个其他现象,就是数据库在open成功的同时(同一秒内),开始报异常.重启之后直接报
ORA-00704: bootstrap process failure
ORA-00704: bootstrap process failure
ORA-00600: internal error code, arguments: [16703], [1403], [20], [], [], [], [], [], [], [], [], []

以及以往恢复经验和mos,基本上可以确定是由于tab$和obj$记录不匹配导致该问题.而且是obj#=20的记录在tab$和obj$中不匹配.

这里可以明确表示tab$无记录,obj$有记录,从而启动的过程出现ORA-600 16703错误可以很好解释.由于数据库启动成功和报错几乎同时进行，以及上面看到的tab$记录不存在的情况，初步怀疑是有startup触发器清空tab$表记录
工具分析触发器表trigger$

这里果然看到一个after startup on database的触发器,名字为DBMS_SUPPORT_DBMONITOR,而它调用的是DBMS_SUPPORT_DBMONITORP存储.

工具分析pl/sql表source$

对wraped加密的程序进行解密

这里可以明确的看到DBMS_SUPPORT_DBMONITORP存储过程备份tab$表到orachk中然后delete tab$表,现在已经明确是由于DBMS_SUPPORT_DBMONITOR触发器在数据库重启之后开始执行调用DBMS_SUPPORT_DBMONITORP程序,如果判断数据库创建时间大于等于300天,便干掉tab$表,实现数据库破坏.

查找DBMS_SUPPORT_DBMONITOR等程序源头
分析相关程序创建时间,通过obj$表的ctime和name来判断

这里可以看出来DBMS_SUPPORT_DBMONITOR和DBMS_SUPPORT_DBMONITORP的创建时间基本上和数据库核心对象的创建时间相差无几,我们可以大概排除掉,是由于pl sql等工具连接数据库导致该发问题(类似:plsql dev引起的数据库被黑勒索比特币实现原理分析和解决方案),很可能是在dbca创建库的过程中就已经带有了DBMS_SUPPORT_DBMONITOR等程序,如果这样那很可能是由于数据库的安装介质被破坏导致该问题.

分析DBMS_SUPPORT_DBMONITOR来源

这里已经很清晰,由于prvtsupp.plb被人注入了恶意脚本从而使得数据库被创建了DBMS_SUPPORT_DBMONITOR的触发器和DBMS_SUPPORT_DBMONITORP的存储过程,从而实现了对数据库的而易破坏.

确定破坏文件prvtsupp.plb来源于介质

这里比较明显,文件就是来源database\stage\Components\oracle.rdbms.dbscripts\11.2.0.4.0\1\DataFiles\filegroup2.jar\rdbms\admin\prvtsupp.plb文件被修改导致

通过md5码对比,可以确定是有人对软件的安装介质进行了破坏,从而实现了恶意代码的注入,从而实现了数据库300天之后重启之后无法正常启动而是出现类似ORA-00600: internal error code, arguments: [16703], [1403], [20], [], [], [], [], [], [], [], [], []的错误.

温馨提示
各位一定要从官方途径下载oracle安装介质,如果是从其他互联网途径下载一定要验证md5,确保文件没有被人恶意篡改,造成无可挽回的损坏.如果真的不幸遇到这类问题,请保护现场联系我们

Incident 176395 created, dump file: /oracle/diag/rdbms/xifenfei/xifenfei/incident/incdir_176395/xifenfei_ora_51261_i176395.trc
ORA-00600: internal error code, arguments: [16703], [1403], [20], [], [], [], [], [], [], [], [], []

报错信息明显,由于select rowcnt,blkcnt,empcnt,avgspc,chncnt,avgrln,nvl(degree,1), nvl(instances,1) from tab$ where obj# = :1无法正常执行.从而出现了ORA-600 16703的错误,更加直接一点的解释就是obj#=20的对象在tab$中找不到记录，从而出现此类报错.和官方解释ORA-600 TAB$和obj$不匹配一致.

分析system文件
通过dul等工具分析system文件发现tab$表记录为空

发现在obj$中有创建表ORACHKBEC66CBE055000000000001(ORACHK+16进制24位)的一个表名字

该表用途通过分析数据库日志发现
create table ORACHKBEC66CBE055000000000001 tablespace system as select * from sys.tab$;
也就是说,这个orachk的表是用来备份tab$的,然后进一步发现有delete from tab$.至此基本上分析清楚,tab$表备份到ORACHK表中,然后delete tab$表数据.实现数据库破坏以及难以恢复的效果.有点类似plsql dev引起的数据库被黑勒索比特币实现原理分析和解决方案的破坏案例
我们可以通过使用bbed对tab$表数据数据进行恢复实现数据库正常启动,实现数据0丢失,最大限度抢救您的数据和减少业务恢复时间

源头已经分析清楚,是有人篡改了oracle安装介质,导致数据库运行300天之后出现该问题,具体见:警告：互联网中有oracle介质被注入恶意程序导致—ORA-600 16703
