A FBI-DHS JAR report released implicated Russian hacking group APT28 and APT29 in attacks against 2016 Presidential Election. This is the first time that the JAR attributes a malicious cyber activity to specific countries or threat actors. Both groups used multiple malware in their campaigns, including the XTunnel malware, the Fysbis backdoor, the Komplex Trojan, and the Carberp malware. The attacks targeted more than US recipients in April 2015 as part of a spear phishing campaign.”]
