At the same time, Gadolinium has embraced another trend found in organized hacking circles—the move away from custom malware and the increased use of open source tools, such as PowerShell. Because the tools are so widely used for benign and legitimate tasks, their malicious use is much harder to detect. Rather than rely on custom software for controlling infected devices, Gadolinium has recently begun using a modified version of the
