The Sofacy threat group continues to carry out attacks using their Zebrocy tool. We first wrote about the Zebrocy tool in a blog that discussed Sofacy’s parallel attack campaigns during the first quarter of 2018, and more recently during Sofacy attacks in late October and early November. The developers of Zebrocy have once again created a new version the Trojan using a different programming language, specifically the Go language.
