Credential Stuffing

What is Credential Stuffing?

Credential stuffing is a cyberattack where hackers use automated tools to test large lists of stolen usernames and passwords against various websites. This attack exploits the common habit of users reusing the same login credentials across multiple online platforms.

Why It Matters

• It is a highly effective method for gaining unauthorized access to user accounts on a massive scale.

• Successful attacks lead to data breaches, identity theft, and fraudulent financial transactions.

• Businesses must implement rate limiting and multi-factor authentication to defend against these automated login attempts.
