Okta warns of credential stuffing attacks targeting its Customer Identity Cloud (CIC) feature since April.

A credential stuffing attack is a type of cyber attack where hackers use large sets of username and password combinations, typically obtained from previous data breaches, phishing campaigns, or info-stealer infections, to gain unauthorized access to user accounts on various online services. Credential stuffing attacks exploit the widespread practice of using the same login credentials across multiple online accounts. Attackers automate the process of trying these credentials on various websites until they find a match, granting them unauthorized access to compromised accounts. This method poses a risk of exposing sensitive data or enabling fraudulent activities.
