::: Greetings :::

Little FAQ:

.1. 
Q: Whats Happen?
A: Your files have been encrypted. 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 us.

.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 mailboxes: tsai.shen@mailfence.com or nicetomeetyou@onionmail.org

.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.

通过分析确认该文件就是头部32个block被破坏,因为oracle数据库中前面32个block是不含业务数据(主要是文件头和位图信息),通过自研的Oracle数据文件加密勒索恢复工具对其进行修复
