On the basis of this threat actor’s past behaviour, we predicted last year that Zebrocy would continue to innovate in its malware development. The group has developed using Delphi, AutoIT, .NET, C# and PowerShell. Since May 2018, Zebrocy has added the “Go” language to its arsenal – the first time...
