Rogue external MFA providers can steal passwords during logins
Summary
Security researchers have devised an attack where a threat actor with privileged access can register a malicious external MFA provider. This rogue provider then intercepts and steals user passwords during legitimate login attempts.
IFF Assessment
FOE
This attack represents a new method for adversaries to steal credentials, directly undermining the security provided by multi-factor authentication.
Defender Context
This highlights a potential vulnerability in how external MFA providers are managed and integrated. Defenders should be aware of the risks associated with third-party MFA integrations and implement strict vetting and monitoring processes for any external services handling authentication.
