Token Theft and AiTM Attacks: How to Stop MFA Bypass in Microsoft 365

MFA is still essential, but attackers now bypass it with Adversary-in-the-Middle (AiTM) phishing, stealing session tokens to hijack signed-in sessions without needing the password. This session breaks down the token theft attack lifecycle, from credential phishing through to business email compromise, data theft, persistence and lateral movement.

It looks at why MFA alone is no longer enough and which Microsoft 365 controls help detect, prevent and contain these attacks. That includes Defender for Office 365, Conditional Access, Identity Protection, web filtering, automated response and continuous monitoring. You leave with a layered, defence-in-depth blueprint.

This is a partner training session on the Cloud Champion portal, delivered by Cloud Capsule. It's pitched at Microsoft partners and MSPs protecting their customers' environments, though much of it applies to in-house IT teams too.
