Description
Bifrost is a remote access trojan that has been active since 2004 and gives operators backdoor control over infected Windows systems. It supports file management, process control, and payload downloads, and its long development history has produced many variants that evade outdated detection signatures. Cyberattackers distribute it through spam, exploit kits, and bundled installers, and its persistence and feature set have kept it in circulation for two decades.
