Multi-Factor Authentication (MFA) blocks 99.9% of account compromise attempts. But attackers are finding ways around it. The remaining 0.1% of attacks target specific weaknesses like token theft (up 111% in 2024), MFA fatigue, SIM swapping, and Adversary-in-the-Middle (AiTM) tactics.

The Reality of Modern Attacks

MFA adds security through a second factor, like a phone app push, SMS code, or hardware token. It stops most basic attacks but falls short against determined attackers. As Wayne Reiner, Structured Cloud Security Engineer, explains: "MFA is your door lock. CA is your smart security system. Without context, like sign-in risk or device health, you're still exposed."

Token Theft and AiTM Attacks

Token theft through AiTM phishing sites poses a major risk. Criminals capture session tokens after users complete MFA. These stolen tokens let attackers bypass security without triggering new MFA checks.

The 2024 MGM Resorts breach shows what's at stake. Using AiTM techniques to steal tokens after MFA approval, attackers caused over $100 million in damage. Microsoft found these attacks increased 111% in 2024, threatening businesses across healthcare IT to manufacturing IT.

What is Conditional Access?

Conditional Access (CA) fills MFA's gaps. This policy engine checks multiple factors before granting access. Instead of just "who are you and what do you have?", CA asks "who are you, where are you, what device are you using, what's your risk level, and what are you trying to access?"

Key Signals Used by Conditional Access:

  • User Identity: Checks group memberships and roles, not just login credentials
  • Location: Blocks access from suspicious regions
  • Device State: Verifies device security status and management
  • Application Sensitivity: Matches security to data importance
  • Real-time Risk Assessment: Spots red flags like impossible travel times

How Conditional Access Protects Your Business

CA policies create smart security rules:

  • Require MFA: Triggers extra verification for risky situations
  • Block Access: Stops suspicious attempts immediately
  • Require Compliant Devices: Only allows secure, managed devices
  • Enforce Session Controls: Limits user actions and requires regular reverification
