What does credential stuffing involve?

• A. Sending phishing emails
• B. Testing stolen usernames and passwords
• C. Exploiting unpatched vulnerabilities
• D. Manipulating individuals into revealing information

Answer: (B)

Credential stuffing is a cyber attack method where an attacker takes advantage of previously stolen usernames and passwords to gain unauthorized access to users’ accounts across various online services. This is particularly effective because many individuals reuse their login credentials across multiple platforms. By automating the process of trying these combinations on numerous sites, attackers can quickly identify accounts that have been compromised. The effectiveness of credential stuffing relies on the fact that once a person's credentials are leaked through a data breach or other means, they are often used in a similar format on other websites, making it easy for attackers to succeed with their attempts. This highlights the importance of using unique passwords for different accounts and utilizing additional security measures—like two-factor authentication—to mitigate the risk of unauthorized access. Understanding credential stuffing underscores the need for robust cybersecurity practices, as it illustrates the potential dangers of password reuse and the role that stolen credentials play in facilitating cyber threats.
