It can be infuriating, especially if there were a lot of steps to get that shell. Let's say you run a command, and it hangs, and you instinctively hit Control-C to cancel it. Perhaps the most annoying thing that can happen (I'm sure it's happened to many of you) is accidentally losing your session by hitting the wrong keys.

That means things like tab completion, keyboard shortcuts, and terminal history simply aren't present. A dumb shell is a type of shell that doesn't have a proper terminal's full functionality. It can often be frustrating when working with reverse shells if all you have is a "dumb" shell. Luckily, with a few commands, we can upgrade to a fully interactive shell with all the bells and whistles. Certain things don't work in these environments, and they can be troublesome to work with. But often, these shells are limited, lacking the full power and functionality of a proper terminal. One of the most exciting things as an ethical hacker, in my opinion, is catching a reverse shell.
