What is Credential Stuffing? (BREAKOUT TREND)

Credential stuffing is a cyberattack where hackers use stolen email and password combinations from data breaches to try logging into other accounts. If you reuse passwords, one breach can compromise ALL your accounts.

⚠️ The Problem:

When companies get hacked, your email and password get leaked. Hackers then try that same email/password on hundreds of other sites. If you reuse passwords, they can access ALL your accounts.

How Credential Stuffing Works:

  1. Data Breach Happens

    A company you use gets hacked. Your email and password are stolen and sold on the dark web.

  2. Hackers Buy Your Credentials

    Scammers buy lists of stolen emails/passwords from data breaches. These lists contain millions of accounts.

  3. Automated Attack Begins

    Hackers use bots to try your email/password on hundreds of websites automatically. They test Gmail, Facebook, Amazon, banks, etc.

  4. Your Accounts Get Hacked

    If you reused that password anywhere, hackers can now access ALL those accounts. They can steal money, personal info, or use your accounts for scams.

How to Protect Yourself:

✅ The Solution:

  1. Check if Your Email Was Breached - Use SpamScore's free breach checker above to see if your email was exposed.
  2. Use Unique Passwords - Never reuse passwords. Use a password manager to generate unique passwords for each account.
  3. Enable 2FA Everywhere - Two-factor authentication stops hackers even if they have your password.
  4. Monitor Your Accounts - Check for suspicious activity regularly. Set up alerts for new logins.
  5. Change Breached Passwords Immediately - If your email was found in a breach, change that password everywhere you used it.
