Credential stuffing’s popularity rose dramatically in 2018 — in fact, Akamai recorded nearly 30 billion credential stuffing attacks in 2018 — and businesses certainly haven’t seen the last of this type of cyber attack.

So businesses that take cybersecurity seriously need to protect against credential stuffing cyber attacks.
A credential stuffing attack is a type of brute force cyber-attack used to gain unauthorised access to one or more user accounts.

Implementing the following proactive and reactive company cybersecurity measures will further reduce the likelihood that a business’s systems will be compromised by a credential stuffing attack.
