Credential Stuffing: Understanding the Threat and How to Protect Yourself

Credential stuffing is a type of cyber attack in which a hacker uses a list of stolen usernames and passwords to gain unauthorized access to multiple accounts. Then, the attacker uses automated software to input the stolen login credentials into various websites and apps, hoping that some of them will match valid accounts.

Credential stuffing aims to gain access to as many accounts as possible to steal personal information, commit fraud, or spread malware. The attacker can use the stolen information for financial gains, such as making unauthorized purchases or transferring money. They can also use the access to spread malware to the victim’s contacts or to use the account as a “pivot point” to gain access to other systems.

Credential stuffing is possible because many people reuse the same usernames and passwords across multiple accounts. As a result, when a website or app suffers a data breach, the hackers may obtain many login credentials, which they can use in a credential-stuffing attack.

To protect yourself from credential stuffing, using unique and strong passwords for each account and enabling two-factor authentication whenever possible is essential. It would help if you also were cautious of any emails or text messages asking for your login information and avoided clicking on links or entering your information on websites you’re not sure are legitimate.

Additionally, as an organization, you can take proactive steps such as using security solutions like bot management and IP reputation services to detect and block IPs and user agents associated with automated attacks. Also, implementing a password policy that enforces strong and unique passwords can help in reducing the risk of a successful credential-stuffing attack.

In conclusion, Credential stuffing is a severe threat that can cause significant damage to both individuals and organizations. However, by being aware of the risk and taking appropriate precautions, you can protect yourself and your accounts from this type of cyber attack.
