Background for this topic.
A remote access trojan (RAT) is malware that gives an unauthorized operator remote control over an infected device. Depending on its design, it may execute commands, browse or copy files, log keystrokes, capture screens, or use a microphone or camera. RATs commonly communicate with attacker-controlled command-and-control infrastructure; capabilities and persistence vary, so reporting should identify the specific family or tool rather than assume every RAT has the same functions.
The main concerns are covert access, exposure of sensitive data, and use of the host to deploy additional malware or alter systems. Defenders should monitor endpoint processes and network behavior, restrict unnecessary outbound connections, keep software patched, and use endpoint controls that can detect unusual remote-control activity. If a RAT is suspected, isolate the device, preserve relevant logs and malware samples, investigate related accounts and hosts, and rotate credentials after containment; blocking one server alone may not remove persistence.
