MFA is no longer enough on its own.
Adversary-in-the-Middle (AiTM) phishing attacks don't steal passwords — they wait until you've successfully logged in, then steal the session cookie that proves authentication already happened.
Microsoft tracked a 146% rise in AiTM attacks over the past year, largely driven by phishing-as-a-service platforms that let even low-skilled attackers run these campaigns at scale.
The businesses most exposed are the ones that built their security posture around the login screen and stopped there.
In our latest post we cover:
→ How AiTM reverse proxies actually work
→ Why MFA doesn't stop session hijacking
→ The controls that do — including phishing-resistant MFA and Conditional Access policies
MFA won't stop AiTM phishing. Learn how attackers steal session cookies after login — and the controls that actually reduce your risk.
