Credential Stuffing and Password Stuffing are malicious cyber-attacks that leverage compromised login credentials from previously hacked 3rd party services^[0][1] to gain unauthorized access to other websites. This type of attack exploits the tendency of users to reuse the same username and password combination across multiple sites, thereby increasing the chances of success in accessing other websites. In order to prevent credential stuffing, users must avoid reusing their credentials across multiple sites. Implementing strong password policies, such as the use of two-factor authentication, further bolsters security and helps protect against credential stuffing attacks. Additionally, organizations can deploy automated tools to detect and block automated login attempts, as well as sophisticated security measures to detect and respond quickly to malicious activities.
