Infected with Java Ransomware? Need to decrypt your files?

What is Java Ransomware

Java Ransomware is crypto-virus, that belongs to Crysis/Dharma family and appends following extensions to affected files:

.id-{id}.[gettkey@qq.com].java, .id-{id}.{mazma@india.com}.java, .id-{id}.{decrypthelp@qq.com}.java, .id-{id}.{faremar@cock.li}.java, .id-{id}.[black.mirror@qq.com].java, .id-{id}.[stopstorage@qq.com].java, .id-{id}.[btc2018@qq.com].java, .id-{id}.[bacon@oddwallps.com].java, .id-{id}.[sabantui@tutanota.com].java.

This ransomware uses AES asymmetric cryptography algorithm. After successful encryption, Java Ransomware creates text file README.TXT and opens windows with following content:
