RAT
CHAOS RAT
CHAOS RAT is an open-source Go remote-access framework with a self-hosted controller that creates configured Windows and Linux clients. Its client connects to an operator-selected controller for remote command handling. Acronis has documented malicious CHAOS RAT Linux samples; the upstream project itself is dual-use.
