It is possible, but not definitive. The leak may stem from vulnerabilities in the customer's browser, malicious plugins, or virus programs, resulting in the exposure of their login credentials after accessing your website. While the root cause may indeed lie with the customer, the fact that their accounts have been compromised on your website indicates a potential risk of Account Takeover (ATO), which could still undermine customer trust in your business.

Does the appearance of our company's customer login credentials in the leaked list mean that our company has suffered data breaches?

Firstly, implement anomalous login detection and Two-Factor Authentication (2FA) strategies to trigger security measures when a user's IP or device changes. Secondly, regardless of whether anomalous login detection and 2FA are enabled, utilizing our company's dark web intelligence to lock compromised accounts is a good option, requiring users to re-authenticate and update their login credentials upon the next login. Thirdly, similar to the "Dark Web Monitoring" services offered by GMAIL and PROTON for their VIP customers, you could offer a similar service to your clients, informing them which passwords have been leaked on the dark web. This will enhance their trust in your security strategies.

What security strategies can I adopt to mitigate the impact of these compromised accounts on customers and provide better service?

The implementation of Two-Factor Authentication (2FA) strategy can significantly reduce the risk of Account Takeover (ATO), yet it can't eliminate the risk completely. For instance, in addition to password authentication, your website may also utilize email authentication. However, if the email account used for verification is leaked, it can still lead to the risk of Account Takeover (ATO). Moreover, even if your website incorporates SMS verification, attackers still have the possibility of intercepting the verification messages through techniques such as fake base stations. Although it has increased the cost of attacks, there are still numerous means to target Two-Factor Authentication (2FA). Therefore, utilizing dark web intelligence to lock the leaked accounts and modify login credentials remains one of the most cost-effective security measures you can adopt.

If I have already strengthened account security with Two-Factor Authentication (2FA), does it imply that I can prevent the risk of Account Takeover (ATO), even without utilizing any dark web intelligence?

Summary：Multi-factor authentication (MFA) has quite rightly become the de facto standard for strengthening access controls. Yet even the best MFA implementations leave a critical gap: weak, reused or compromised passwords. When an attacker bypasses or circumvents MFA (whether by tricking a user into approving a push notification or exploiting a fallback) those same poor passwords become the attacker’s key to your systems.
