BIFROSTBifrost

Bifrost is a discontinued backdoor trojan horse family of more than 10 variants which can infect Windows 95 through Windows 10 (although on modern Windows systems, after Windows XP, its functionality is limited). Bifrost uses the typical server, server builder, and client backdoor program configuration to allow a remote attacker, who uses the client, to execute arbitrary code on the compromised machine (which runs the server whose behavior can be controlled by the server editor).
