WEBINAR BRIEFING

Case Study: Multi-Actor Intrusion in Business Email Compromise

What happens when not one, but two threat actors gain access to the same environment without triggering a single alert?

In this session, we take you inside a business email compromise (BEC) incident investigated by Eye Security. What started as a single phishing email quickly escalated into a multi-actor intrusion, with threat actors bypassing MFA, hijacking sessions, and using trusted identities to spread further inside the organisation.

This is a step-by-step reconstruction of how modern BEC attacks unfold in Microsoft 365, from initial access to internal phishing, data exposure, and persistence.

Along the way, we break down the techniques used, including adversary-in-the-middle phishing, and show why classic controls often fail.

“We balanced Eye Security’s costs against the value they would bring and the ROI stood up to scrutiny. The solution we now have in place prevents incidents and works with proven EDR and AI technology, which gives us peace of mind.”
