The cost of an attack has dropped by orders of magnitude – now your account is worth about as much as a cup of coffee.
Credential Stuffing remains one of the most popular hacking methods. By using lists of compromised usernames and passwords, attackers gain access to other services where users reuse the same credentials. Automated tools enable them to carry out such attacks on a massive scale.According to Abnormal Security, one such tool is Atlantis AIO—a program capable of testing millions of logins and passwords across more than 140 platforms within minutes. The utility includes ready-made modules for popular online services, especially email providers like Hotmail, Yahoo, and AOL.
The program automates password cracking and allows attackers to hijack accounts without manual intervention. Once access is gained, it is used for sending phishing emails, collecting data, or reselling on underground forums.
Atlantis AIO is organized on a modular basis. Specialized modules target email services, financial platforms, streaming services, and even delivery services. Its password-cracking modules enable quick testing of combinations on vulnerable accounts, while recovery modules help bypass CAPTCHAs and other security mechanisms.
Compromised usernames are mass-marketed – often in tens of thousands, including both personal and corporate addresses. This phenomenon is facilitated by the common reuse of passwords by employees at work and at home.
Traditional security measures—complex passwords, password managers, and two-factor authentication—are no longer always effective. Criminals find ways to bypass even MFA and continue using automated tools for large-scale attacks.
To counter Credential Stuffing, it is crucial to prevent the theft of logins from the outset. Modern AI systems can detect phishing, identify anomalous activity, and automatically block hijacking attempts. These solutions help protect corporate data and stop attacks before accounts are even accessed.
