WHAT’S THE RISK? 81% of hacking-related breaches leveraged either stolen and/or weak passwords. The use of weak and default passwords is one of the leading causes of data breaches for businesses. Passwords are essential for computer and payment data security. But to be effective, they must be strong and updated regularly. Computer equipment and software out-of-the-box (including payment terminals) often come with vendor default or preset passwords such as “password” or “admin”, which are commonly known and easily exploited by criminals.
