Description(Cylance) Denis is a simple backdoor developed by the OceanLotus Group, well observed in-the-wild and renowned for using DNS tunneling as a transport mechanism for C2 communications. Denis is typically deployed early in the attack lifecycle, and it appears to be less tailored/targeted than the more advanced backdoors that are utilized once a foothold has been established within an environment.
