What is Credential Stuffing?
Credential stuffing is an attack where criminals take username and password combinations leaked from one breach and automatically try them across thousands of other services. It succeeds because people reuse the same password on multiple sites.
Why Credential Stuffing matters for Australian businesses
With cyberattacks on Australian businesses increasing year on year, understanding your security tools and strategies is critical. The Australian Cyber Security Centre reports an attack every six minutes, and small and medium businesses are increasingly targeted. Having the right defences in place is not optional — it is essential for protecting your data, your clients, and your reputation.
For small and medium businesses in particular, understanding credential stuffing is essential to maintaining a secure, efficient, and resilient IT environment. Whether you are reviewing your current defences or planning improvements, knowing how these threats work and how to stop them will help you have more informed conversations with your IT provider and make better decisions for your business.

Frequently Asked Questions
What is credential stuffing?
It is the automated testing of leaked username-password pairs against other websites and services, exploiting the human habit of reusing passwords across accounts.
How is credential stuffing different from brute force?
Brute force guesses passwords from scratch, while credential stuffing uses real credentials already leaked from other breaches, making it far more efficient for attackers.
How do we stop credential stuffing?
Require unique passwords via a password manager, enforce MFA everywhere, and monitor for staff credentials appearing in known breaches so they can be reset quickly.
