SUMMARY

Banks are facing a new cybersecurity challenge: attackers use  AI and infostealer malware to steal authenticated sessions — not just passwords — making it almost impossible to detect account takeovers.

This webinar focused on how banks must move from login-based security to continuous monitoring of customer behavior while connected. Speakers agreed that AI is helping both attackers and banks, making the race for trust and fraud prevention more critical than ever.

Key topics

The rise of infostealers and hijacking

Modern infostealers capture authenticated sessions and tokens, enabling account takeover even after successful authentication.

Continuous trust replaces traditional authentication

Banks can’t rely on login security alone. Continuous monitoring of user behavior, device activity, and transactions helps detect suspicious actions throughout the session.

AI is accelerating cybercrime and cyber defence

AI enables more sophisticated, automated fraud — while helping banks improve detection, risk assessment, and threat monitoring.

Less passwords, more behavior control

Passkeys and biometrics reduce password dependency, but the strongest security combines passwordless authentication with behavioral and contextual analytics.
