sso attacks

SSO attacks are a growing threat in enterprise security, as demonstrated by modern vishing kits that combine real-time phishing with phone-based social engineering to bypass multi-factor authentication. These sophisticated attacks target single sign-on systems from Google, Microsoft, Okta, and cryptocurrency providers, using phishing-as-a-service tools that dynamically adapt to legitimate authentication flows. The technique involves a two-person operation where a caller guides the victim through a fake login while the kit manipulates the browser UI in real time. This tag covers discussions on how these MFA-defeating attacks work, their impact on SSO security, and the challenges they pose for IT teams defending against credential theft and account takeover.
