In June, a staff member at a customer’s company clicked a phishing link and entered their Microsoft 365 credentials.
It wasn’t just a fake login page. It was an Adversary-in-the-Middle (AitM) attack, designed to intercept login details and steal the user’s session token.
That token let the attacker bypass multi-factor authentication (MFA) and gain full access to the account.
But the attacker didn’t get far.
Our Managed Detection and Response (MDR) system flagged the suspicious login instantly.
Our monitoring triggered an automatic forced sign-out, cutting off access before anything could be stolen.
Within minutes, our team had:
– Escalated the incident to our security team
– Guided the user through a secure password reset
– Re-registered MFA
– Completed a full audit to confirm no data access or lateral movement
No breach. No data loss. No downtime.
What the Attack Looked Like
The phishing link led to a convincing spoofed Microsoft 365 login page:

After the user logged in, the attacker captured their credentials and the session token — allowing them to start a real Microsoft 365 session. That’s why even MFA couldn’t stop it.
What We Did Next
We helped the customer level up their defences by:
Recommended Next Steps:
– Enforcing stronger MFA registration policies
– Recommending conditional access based on risk, location, and device
– Supporting phishing-resistant MFA options (like FIDO2 keys)
– Improving user training with real-world phishing simulations
Why It Matters
Cybersecurity is no longer just about good tools. It’s about real-time response and smart strategy.
This case proves how MDR turns potential breaches into non-events. If your business relies on Microsoft 365, protection like this isn’t optional.
