Webinar: How attackers bypass MFA and how defenders can respond

Multi-factor authentication remains vulnerable to sophisticated phishing techniques that bypass traditional security controls. Device Code phishing attacks specifically target MFA implementations by manipulating the device authentication flow, allowing attackers to gain access to corporate accounts without ever obtaining user passwords.

In Device Code phishing attacks, threat actors trick users into authorizing device codes through deceptive prompts. These codes grant legitimate access tokens, effectively circumventing MFA protections entirely. The attack works because users often fail to recognize the authorization request as unauthorized, particularly when the phishing interface mimics legitimate OAuth flows.

Organizations defending against these attacks face a detection challenge. By the time security teams identify a compromised account, attackers may have already established persistent access or exfiltrated sensitive data. Traditional MFA logs alone do not reveal the behavioral anomalies preceding unauthorized access.

Behavioral AI addresses this gap by establishing baselines of normal user activity. The technology detects deviations such as login attempts from unusual geographic locations, abnormal access times, or atypical resource requests. When these patterns diverge from established behavior, behavioral AI flags accounts for investigation before attackers can cause damage.

Automating response workflows amplifies detection effectiveness. Security teams can configure automated actions such as forcing password resets, revoking active sessions, or triggering additional authentication challenges when behavioral AI identifies suspicious activity. These responses compress the window between detection and containment.

The webinar addresses practical implementation strategies for organizations implementing behavioral AI alongside existing MFA deployments. Security teams learn to differentiate between legitimate user behavior changes and genuine compromise indicators, reducing false positives that degrade team efficiency.

Defenders must recognize that MFA alone provides incomplete protection. Attackers invest in phishing techniques specifically designed to work around these controls. Organizations deploying behavioral analytics alongside MFA create layered defenses that detect compromise through behavioral anomalies rather than relying solely on authentication factor validation.
