There's new Windows malware circulating, but no one knows what its intentions are.

Cybersecurity researchers at Red Canary recently discovered a new worm-like malware they’ve dubbed Raspberry Robin, which spreads via infected USB drives. While they’ve been able to observe and study the malware’s mechanics, they haven’t been able to determine its ultimate purpose.

"[Raspberry Robin] is an interesting story whose ultimate threat profile is yet to be determined," Tim Helming, security evangelist at DomainTools, told Lifewire via email. "There are too many unknowns to hit the panic button, but it's a good reminder that building strong detections and taking sensible security measures have never been more important."

Helming explains that understanding the ultimate goal of malware helps assess the level of risk.
