This is how to respond to a credential-stuffing attack

This type of attack typically involves a combination of technical measures and proactive security practices.

Here's a five-step response plan🫡

1. Monitor network traffic and authentication logs for signs of abnormal login attempts, such as a sudden surge in failed login attempts or access from unfamiliar locations or devices.

Use security tools to detect patterns indicative of credential-stuffing attacks.

2. Immediately block or throttle traffic from suspicious IP addresses or ranges associated with the attack. Implement rate limiting or CAPTCHA challenges on login pages to deter automated login attempts.

3. Notify affected users and prompt them to reset their passwords.

Encourage them to choose strong, unique passwords and enable multi-factor authentication (MFA) to enhance account security.

4. Require users to verify their identity using an additional factor, such as a one-time code sent to their mobile device, in addition to their password.

MFA adds an extra layer of security and helps prevent unauthorised access, even if login credentials are compromised.

5. Evaluate and strengthen security measures to prevent future credential stuffing attacks.

Consider implementing measures such as IP blacklisting, web application firewalls (WAFs) and bot detection solutions to mitigate the risk of automated attacks.

Regularly monitor for suspicious activity and update security protocols as needed to stay ahead of evolving threats
