Credential Stuffing

Credential Stuffing: How You Can Prevent It

Although no criminals have successfully used this strategy to access accounts at First Financial Bank, we want our customers to be on alert of the increased risk brought about by these uncertain times. 

What is Credential Stuffing?

Credential stuffing is a type of cyber-attack in which hackers take large amounts of usernames and passwords and try to "stuff" those credentials into the login page of other digital services. Because people often use the same username across multiple platforms, hackers can use the information gathered from credential stuffing to unlock multiple accounts. Then, with the use of automated tools, hackers can attempt thousands of login credentials in a matter of minutes. In recent years, hundreds of millions of credentials have been stolen and sold to commit fraud. 

How can I prevent it?

  • Avoid generic usernames that include your first or last name, or first initial and last name
    • For example: Jane Doe could be written as J@n3 D0e
  • Include numbers and special characters in both your usernames and passwords
  • Frequently change your account usernames and passwords
  • Use different usernames and passwords across online platforms
  • When possible, avoid using your email address as a username

Creating a TEXAS STRONG Password

Creating a strong password is easier than you think. Follow these simple tips to shake up your password protocol:

  • Use a long passphrase. According to NIST guidance, you should consider using the longest password or passphrase permissible. For example, you can use a passphrase such as a news headline or even the title of the last book you read. Then add in some punctuation and capitalization.
  • Don’t make passwords easy to guess. Do not include personal information in your password such as your name or pets’ names. This information is often easy to find on social media, making it easier for cybercriminals to hack your accounts.
  • Avoid using common words in your passwords. Substitute letters with numbers and punctuation marks or symbols. For example, @ can replace the letter “A” and an exclamation point (!) can replace the letters “I” or “L.”
  • Get creative. Use phonetic replacements, such as “PH” instead of “F”. Or make deliberate, but obvious misspellings, such as “enjin” instead of “engine.”
  • Keep your passwords on the down-low. Don’t tell anyone your passwords and watch for attackers trying to trick you into revealing your passwords through email or calls. Every time you share or reuse a password, it chips away at your security by opening up more avenues in which it could be misused or stolen.
  • Unique account, unique password. Having different passwords for various accounts helps prevent cyber criminals from gaining access to these accounts and protect you in the event of a breach. It’s important to mix things up— find easy-to remember ways to customize your standard password for different sites.
  • Double your login protection. Enable multi-factor authentication (MFA) to ensure that the only person who has access to your account is you. Use it for email, banking, social media, and any other service that requires logging in. If MFA is an option, enable it by using a trusted mobile device, such as your smartphone, an authenticator app, or a secure token—a small physical device that can hook onto your key ring. 
  • Utilize a password manager to remember all your long passwords. The most secure way to store all of your unique passwords is by using a password manager. With just one master password, a computer can generate and retrieve passwords for every account that you have – protecting your online information, including credit card numbers and their three-digit Card Verification Value (CVV) codes, answers to security questions, and more.
