.[OnlyBuy@cyberfear.com].REVRAC勒索mysql恢复

发表于 2025 年 3 月 13 日 由 惜分飞

有朋友接到一个mariadb库被加密的case,部分文件被加密为:.[D2BB58C7].[OnlyBuy@cyberfear.com].REVRAC扩展名
revrac

黑客预留的+README-WARNING+.txt内容类似:

YOUR FILES ARE ENCRYPTED

Your files, documents, photos, databases and other important files are encrypted.

You are not able to decrypt it by yourself! The only method of recovering files is to purchase an unique private key.
Only we can give you this key and only we can recover your files.

To be sure we have the decryptor and it works you can send an 
    email: TechSupport@cyberfear.com  and decrypt one file for free.

Before paying you can send us up to 1 file for free decryption. The total size of files must be less than 1Mb 
(non archived), and files should not contain valuable information. (databases,backups, large excel sheets,sql. etc.) 

Do you really want to restore your files?
Write to email: OnlyBuy@cyberfear.com

Your personal ID is indicated in the names of the files and in the end of this message, before writing a message by email
indicate the name of the ID indicated in the files IN THE SUBJECT OF THE EMAIL

Attention!
 * Do not rename encrypted files.
 * Do not try to decrypt your data using third party software, it may cause permanent data loss.
 * Decryption of your files with the help of third parties may cause increased price (they add their fee to our) 
   or you can become a victim of a scam.

通过分析ibd文件没有被破坏
225026

这种情况恢复相对比较简单,可以直接通过对单独ibd文件会的思路进行处理,类似恢复文章:
frm和ibd文件数据库恢复
MySQL 8.0版本ibd文件恢复
[MySQL异常恢复]mysql ibd文件恢复
InnoDB: Cannot open table db/tab from the internal data dictionary of InnoDB though the .frm file for the table exists
当然前提需要有表创建语句,这个客户有昨天的备份的被的.sql备份,通过技术手段分析,确认只有3个表的创建语句丢失,对于丢失的ddl语句,通过直接对ibdata文件解析获取,基于这些信息结合,实现数据的完美恢复

对于类似这种被加密的勒索的数据文件,我们可以实现比较好的恢复效果,如果此类的数据库(oracle,mysql,sql server)等被加密,需要专业恢复技术支持，请联系我们:

系统安全防护措施建议：
1.多台机器，不要使用相同的账号和口令
2.登录口令要有足够的长度和复杂性，并定期更换登录口令
3.重要资料的共享文件夹应设置访问权限控制，并进行定期备份
4.定期检测系统和软件中的安全漏洞，及时打上补丁。
5.定期到服务器检查是否存在异常。
6.安装安全防护软件，并确保其正常运行。
7.从正规渠道下载安装软件。
8.对不熟悉的软件，如果已经被杀毒软件拦截查杀，不要添加信任继续运行。
9.保存良好的备份习惯，尽量做到每日备份，异地备份。

表dml操作权限授权给public,导致只读用户失效

发表于 2025 年 3 月 12 日 由 惜分飞

最近一个客户和我反馈,他们创建了一个只读用户(之时给了create session和select表权限),但是其中有部分表可以执行dml操作,我登录系统进行确认

SQL> SELECT PRIVILEGE, ADMIN_OPTION
  2    FROM DBA_SYS_PRIVS
  3   WHERE GRANTEE =  'ALL_READONLY'
  4  UNION
  5  SELECT PRIVILEGE, ADMIN_OPTION
  6    FROM ROLE_SYS_PRIVS
  7   WHERE ROLE IN
  8         (SELECT GRANTED_ROLE FROM DBA_ROLE_PRIVS WHERE GRANTEE =  'ALL_READONLY')
  9  UNION
 10  SELECT PRIVILEGE, ADMIN_OPTION
 11    FROM ROLE_SYS_PRIVS
 12   WHERE ROLE IN (SELECT GRANTED_ROLE
 13                    FROM ROLE_ROLE_PRIVS
 14                   WHERE ROLE IN (SELECT GRANTED_ROLE
 15                                    FROM DBA_ROLE_PRIVS
 16                                   WHERE GRANTEE = 'ALL_READONLY'));

PRIVILEGE                                ADM
---------------------------------------- ---
CREATE SESSION                           NO

尝试对一个表做dml操作,确实可以对u1.t1表进行dml操作

SQL> conn all_readonly/PASSWORD
Connected.
SQL> update U1.T1 set SNAME='111_test' where sid='www.xifenfei.com';

1 row updated.

SQL> rollback;

Rollback complete.

查看这个表的相关授权,关于all_readonly(只读用户)的授权,也确实只是授权了查询权限

SQL>  SELECT GRANTEE,PRIVILEGE,OWNER,TABLE_NAME  FROM dba_TAB_PRIVS WHERE TABLE_NAME ='T1' and GRANTEE='ALL_READONLY'

GRANTEE              PRIVILEGE                                OWNER                TABLE_NAME
-------------------- ---------------------------------------- -------------------- --------------------
ALL_READONLY         SELECT                                   U1                    T1

既然t1这个表可以被dml操作,那是这个表是否还有其他授权,进一步查询该表授权(不限于ALL_REAONLY用户)

SQL> SELECT GRANTEE,PRIVILEGE,OWNER,TABLE_NAME  FROM dba_TAB_PRIVS WHERE TABLE_NAME ='T1';

GRANTEE              PRIVILEGE                                OWNER                TABLE_NAME
-------------------- ---------------------------------------- -------------------- --------------------
PUBLIC               ALTER                                    U1                    T1
PUBLIC               DELETE                                   U1                    T1
PUBLIC               INDEX                                    U1                    T1
PUBLIC               INSERT                                   U1                    T1
PUBLIC               SELECT                                   U1                    T1
PUBLIC               UPDATE                                   U1                    T1
PUBLIC               REFERENCES                               U1                    T1
PUBLIC               ON COMMIT REFRESH                        U1                    T1
PUBLIC               QUERY REWRITE                            U1                    T1
PUBLIC               DEBUG                                    U1                    T1
PUBLIC               FLASHBACK                                U1                    T1
ALL_READONLY         SELECT                                   U1                    T1

14 rows selected.

这下明确了,由于授权了u1.t1表的(insert,delete,update等)权限给public,导致其他用户也可以对这些表进行授权给public的所有操作.
不管任何原因,都不建议授权表/对象的操作给public,这样会导致登录该数据库的所有用户都具有这个权限,风险不可控

21c数据库恢复遭遇ora-600 ktugct: corruption detected

发表于 2025 年 3 月 11 日 由 惜分飞

接手一个oracle 21c的库恢复请求,通过Oracle数据库异常恢复检查脚本(Oracle Database Recovery Check)脚本检测之后,发现undo文件offline之后,做了resetlogs操作,导致该文件目前处于WRONG RESETLOGS状态
21c
wrong-resetlogs

尝试恢复数据库ORA-16433错误

SQL> recover datafile 1;
ORA-00283: recovery session canceled due to errors
ORA-16433: The database must be opened in read/write mode.

Media Recovery failed with error 16433
ORA-283 signalled during: ALTER DATABASE RECOVER  datafile 1  ...

官方对于该错误的解释

[oracle@iZbp11c0qyuuo1gr7j98upZ ~]$ oerr ora 16433
16433, 00000, "The database must be opened in read/write mode."
// *Cause:  An attempt was made to open the database in read-only mode after an
//          operation that requires that the database be opened in read/write
//          mode.
// *Action: Open the database in read/write mode. The database can then be
//          opened in read-only mode.

对于该错误,可以通过rectl进行解决,但是由于undo文件的resetlog 信息不对,无法直接重建ctl,这种情况下,通过Oracle Recovery Tools小工具对undo文件的resetlogs信息今星期修改
ora-recovery

然后重建ctl成功
