1Introduction
Attackers seize credentials and act as the user.
2Discussion
Credential stuffing tests leaked password lists at scale; phishing, infostealers and SIM swaps are also common.
Signs: many failed logins, new devices or locations, sudden contact changes and new payees.
Defence: phishing-resistant MFA, rate limiting and bot detection, breached-password checks, device and behaviour analytics, step-up for sensitive actions.
3Conclusion
Instant alerts and self-service lock reduce the window of abuse.
