Credential stuffing is a type of cyberattack where hackers use old leaked usernames and passwords to try logging into other accounts. This attack works because many people reuse the same password on multiple websites.
For example, if your password was leaked years ago from a shopping website or gaming app, hackers may still use it today to try accessing your email, banking apps, social media accounts, or work accounts.
Hackers use automated tools that can test thousands of username and password combinations within minutes. Even if the leaked password is old, it can still work if you never changed it or if you reused it on other websites.
Credential stuffing attacks are difficult to notice because hackers do not need to break into an account using advanced methods. They simply use information that was already leaked in the past.
One warning sign is receiving login alerts from websites you do not use often or getting notifications about failed login attempts. Unexpected password reset emails can also be a sign that someone is trying to access your accounts.
The best way to protect yourself is to use different passwords for every important account. If one account is leaked, your other accounts will still remain safe. Enabling two-factor authentication can also provide an extra layer of security.
It is also a good habit to change old passwords regularly, especially if you have not updated them in a long time.
