FortiGuard Labs recently discovered a new campaign of StealthWorker malware, also called GoBrut, that was first reported by Malwarebytes just a few days ago. This malware is written in Golang. Although uncommonly seen being used by malware, it is the same programming language used to develop the module that controlled the bots of Mirai.
