What Makes Credential Stuffing Difficult to Detect?
Credential stuffing is a cyberattack where attackers use stolen usernames and passwords, often obtained from data breaches or bought on the dark web, to gain unauthorized access to accounts on other platforms. These attacks are highly prevalent and a major contributor to data breaches, largely because 64% of users reuse passwords across multiple accounts. On platforms like Auth0, credential stuffing activities account for nearly half of daily login attempts. The risk continues to grow as billions of compromised credentials circulate online, giving attackers endless opportunities to exploit reused passwords.
