Smart appliances that are connected to the internet can be vulnerable to cyber attacks if not properly secured. Common default usernames and passwords like "admin" and "password" are easily guessed and leave devices open to hacking if not changed. It is important to update usernames and passwords on smart appliances to protect privacy and security.
