Detect and respond to Adversary-in-the-Middle (AiTM) phishing attacks that use reverse proxy kits like EvilProxy, Evilginx, and Tycoon 2FA to bypass MFA and steal session tokens, correlating Azure AD/Entra sign-in logs, SIEM alerts, and EDR telemetry. Use when investigating suspected MFA-bypass phishing or session token theft, or building detection and response playbooks against reverse-proxy phishing kits.

# Performing Adversary-in-the-Middle Phishing Detection
## Overview
Adversary-in-the-Middle (AiTM) phishing attacks use reverse-proxy infrastructure to sit between the victim and the legitimate authentication service, intercepting both credentials and session cookies in real time. This allows attackers to bypass multi-factor authentication (MFA). The most prevalent PhaaS kits in 2025 include Tycoon 2FA, Sneaky 2FA, EvilProxy, and Evilginx. Over 1 million PhaaS attacks were detected in January-February 2025 alone. These attacks have evolved from QR codes to HTML attachments and SVG files for link distribution.
## When to Use
- When conducting security assessments that involve performing adversary in the middle phishing detection
- When following incident response procedures for related security events
- When performing scheduled security testing or auditing activities
- When validating security controls through hands-on testing
## Prerequisites
- Azure AD / Entra ID Conditional Access policies
