A type of cyber attack that uses stolen username and password combinations to gain unauthorized access to accounts.
Description
Credential stuffing is a cyber attack method where attackers use lists of stolen usernames and passwords from one data breach to access accounts on various online services. This technique exploits the common practice of users reusing passwords across multiple sites. Once attackers obtain these credentials, they automate the login attempts using bots to infiltrate many accounts quickly. The attack can happen on any platform, from social media to banking websites. Successful credential stuffing can lead to identity theft, financial loss, and unauthorized transactions. Organizations are encouraged to implement multi-factor authentication (MFA) and monitor for unusual activity to mitigate these risks. Regularly updating passwords and educating users about password management is also crucial for reducing the effectiveness of such attacks. This growing threat highlights the importance of cybersecurity measures in protecting sensitive information.
Examples
- In 2019, the popular gaming website Fortnite experienced a credential stuffing attack, leading to unauthorized access to many player accounts.
- In 2020, the online retail platform Shopify reported a significant credential stuffing attack, which compromised customer accounts due to reused passwords.
Additional Information
- Using unique passwords for different accounts can greatly reduce the risk of credential stuffing.
- Implementing rate limiting on login attempts can help websites detect and block suspicious login activities.
