SectopRAT is a remote-access trojan, or RAT, meaning malware built to let an attacker control an infected Windows system from afar. Like many RATs, it can support theft, surveillance, process execution, file access, and persistence, turning a compromised host into a hands-on remote foothold. The exact feature set can vary by build, but the core purpose is the same: maintain covert access and enable post-compromise activity.
SectopRAT matters because RAT infections often look like ordinary software or routine background activity until investigators correlate process behavior, persistence mechanisms, and network connections. Defenders look for suspicious parent-child process chains, unusual scheduled tasks or registry run keys, beaconing to command-and-control infrastructure, and outbound traffic that does not match the host’s normal role. Blocking the initial lure is important, but endpoint telemetry is what usually reveals the remote-control stage.
