This ransomware encrypts files and uses .braincrypt as file name extension for encrypted files.
It leaves a ransom note with the following filename:

The ransom note contains the following text:
YOUR FILES WERE ENCRYPTED.
TO DECRYPT FILES, PLEASE, CONTACT US WRITING ON THIS EMAIL: headlessbuild@india.com
YOUR PERSONAL ID: <Personal ID of your computer, for example: 4df7065b1d049d098526344faaabf3f8>
This ransomware is developed using the Go programming language.
It connects to a certain URL, likely controlled by the attacker, using a specific Go user-agent:
URL: hxxp:// alex-luthor. myjino .ru/ htdocs/gateway/gate.php?uuid=<Personal ID of your computer, for example: 4df7065b1d049d098526344faaabf3f8>
User-agent: Go-http-client/1.1
The ransomware makes this connection presumably to report that your computer has been compromised. However, during analysis, the URL is inaccessible.
