We have labelled this threat group the Gamaredon Group and our research shows that the Gamaredon Group has been active since at least 2013.  In the past, the Gamaredon Group has relied heavily on off-the-shelf tools. Our new research shows the Gamaredon Group have made a shift to custom-developed malware. We believe this shift indicates the Gamaredon Group have improved their technical capabilities.",
