Is Ettercap detectable? It technically shouldn't be because it just reads the data it sees legally through network. Every other computer receives the exact same data, it just doesn't show the data to user since none of it is reserved for that one user.
Is using Ettercap detectable? I mean, it's just my application on my computer, which will analyze a network. It's just inputs and outputs. It's not like Ettercap is reaching into the network. It just read whatever meets my computer.
Additionally, does Ettercap work through LAN/Ethernet? I can't really check myself since I'm on Wi-Fi and my modem has problems with cable networking.
