"value" : "A Trojan for Linux that was named Linux.Mirai has several predecessors. The first malware program belonging to this family was spotted in May 2016 and was dubbed Linux.DDoS.87. At the beginning of August, a new version of this Trojan Linux.DDoS.89 was discovered. Finally, Doctor Web\u00e2\u20ac\u2122s security researchers investigated the \r\nLinux.Mirai Trojan found later that month."
