In my opinion any software that can communicate with anything else then it self can be considered a "hacking tool" when used in a way as such. When connecting to an FTP, typing the wrong password. Is that a hacking tool? Many FTP software keeps trying even if the login attempt failed. Maybe Windows and its talkative SMB protocol may be considered a hacking tool as the built in authorization mechanism by default attempts to login to resources using "the current users credentials" before asking the user.
