Credential stuffing

Credential stuffing is a type of cyberattack where attackers use automated tools to try large numbers of username and password combinations, often obtained from previous data breaches, to gain unauthorized access to user accounts on various online services. This attack exploits the tendency of individuals to reuse the same credentials across multiple sites, making it easier for attackers to gain access to multiple accounts. Credential stuffing primarily targets online services and platforms, posing significant risks to both individual users and organizations by compromising sensitive information and causing financial losses.
