.makop病毒加密数据库恢复

发表于 2021 年 3 月 27 日 由 惜分飞

最近接到客户几套oracle数据库所在的机器文件被加密,readme-warning.txt内容如下

::: Greetings :::


Little FAQ:
.1. 
Q: Whats Happen?
A: Your files have been encrypted and now have the "makop" extension. The file structure was not damaged, we did everything possible so that this could not happen.

.2. 
Q: How to recover files?
A: If you wish to decrypt your files you will need to pay in bitcoins.

.3. 
Q: What about guarantees?
A: Its just a business. We absolutely do not care about you and your deals, except getting benefits. If we do not do our work and liabilities - nobody will cooperate with us. Its not in our interests.
To check the ability of returning files, you can send to us any 2 files with SIMPLE extensions(jpg,xls,doc, etc... not databases!) and low sizes(max 1 mb), we will decrypt them and send back to you. That is our guarantee.

.4.
Q: How to contact with you?
A: You can write us to our mailbox: Evilminded@privatemail.com

.5.
Q: How will the decryption process proceed after payment?
A: After payment we will send to you our scanner-decoder program and detailed instructions for use. With this program you will be able to decrypt all your encrypted files.

.6.
Q: If I don抰 want to pay bad people like you?
A: If you will not cooperate with our service - for us, its does not matter. But you will lose your time and data, cause only we have the private key. In practice - time is much more valuable than money.



:::BEWARE:::
DON'T try to change encrypted files by yourself! 
If you will try to use any third party software for restoring your data or antivirus solutions - please make a backup for all encrypted files!
Any changes in encrypted files may entail damage of the private key and, as result, the loss all data.

故障原因,写丢失导致

Crash or instance recovery may fail because of a lost write even
though one of the mirrors has a good copy.  Reading a file header 
can corrupt a good mirror copy with a bad one.
 
Rediscovery Notes:
 ORA-600 [kcratr_scan_lostwrt] or ORA-600 [kcratr_scan_lastbwr] are signaled 
 even though one of the mirrors has a good copy.

解决方案比较简单直接recover顺利open库
