Ever heard of credential stuffing? It sounds like something out of a tech thriller, but it’s one of the most common—and dangerous—cyberattacks happening right now. The scary part? It doesn’t require hackers to be geniuses. They’re simply taking advantage of something most of us do every day: reusing passwords.
What Is Credential Stuffing?
Credential stuffing is when cybercriminals use stolen usernames and passwords from one breach to try logging into other accounts. Why does this work so well? Because people often reuse the same password across multiple sites. If your password for that old shopping site got leaked, hackers will try it on your email, bank, and social media accounts. And guess what? They succeed more often than you think.
Why It’s So Dangerous
- Automated Attacks: Hackers use bots to test thousands of stolen credentials across multiple platforms in minutes.
- Low Effort, High Reward: They don’t need to crack passwords—they just need you to reuse them.
- Chain Reaction: Once they get into one account, they can pivot to others, reset passwords, and even steal your identity.
How to Protect Yourself
The good news? Stopping credential stuffing is easier than you think. Here’s what you need to do:
- Use Unique Passwords for Every Account
No exceptions. A password manager can help you create and store strong, unique passwords without the headache. - Enable Multi-Factor Authentication (MFA)
MFA adds a second layer of security, like a code sent to your phone. Even if hackers have your password, they can’t get in without that extra step. - Monitor Your Accounts
Check your bank statements and email activity regularly. If something looks off, act fast. - Stay Alert for Data Breach Notifications
If a service you use gets hacked, change your password immediately—before attackers try it elsewhere.
Use tools like Have I Been Pwned to see if your email has been involved in a data breach. If it has, update those passwords ASAP.
Credential stuffing thrives on convenience—our bad habit of reusing passwords. Break that habit today. A few proactive steps can save you from a massive headache tomorrow.
