Recently, a friend of the SQL server database was encrypted with the suffix: .mdf.happythreechoose, which needs to provide recovery support.
Files left by hackers are similar

The query found that the virus and .happyfourchoose belong to the GlobeImposter family. Currently, the solution is not supported.密
Through low-level analysis, it was found that mainly the header and tail of the file were confidential.

Scanned data files and found that most of the data can be recovered

Protection recommendations:
1. Multiple machines, do not use the same account and password
2. The login password should have sufficient length and complexity, and the login password should be changed regularly.
3. The shared folder of important data should be set up with access control and regularly backed up
4. Regularly detect security vulnerabilities in the system and software and apply patches in a timely manner.
5. Periodically go to the server to check if there is any abnormality. View scope includes:
a) Whether there are new accounts
b) Guest is enabled
c) Is there an exception in the Windows system log
d) Is there any abnormal interception of anti-virus software?
6. Install security protection software and ensure its normal operation.
7. Download and install software from regular channels.
8. For unfamiliar software, if it has been intercepted by antivirus software, do not add trust to continue running.
