Man‑in‑the‑Middle (MitM)

What is a Man-in-the-Middle?

A Man-in-the-Middle (MitM) is a technique where a threat actor secretly intercepts communication between a user and an online service. It’s commonly used to steal credentials, bypass multi-factor authentication (MFA), or hijack sessions without the victim’s awareness.

How does a Man-in-the-Middle work?

• Network manipulation: Attacker uses DNS poisoning or rogue Wi-Fi to intercept traffic
• Real-time relay: Login credentials and MFA tokens are forwarded to the real site
• Session hijacking: Access tokens are stolen to maintain persistent access
• Silent interception: The user sees the expected interface without noticing the attack

Man-in-the-Middle techniques are frequently used in advanced phishing operations.

How Memcyco Counters MitM-Based Threats

Memcyco detects and disrupts the downstream effects of MitM tactics, without needing access to the network layer.

How it works:

• In-session detection flags anomalies in referral paths, login flows, and session behavior.

• Decoy credentials are injected to neutralize stolen data and expose credential relay attempts.

• Session context and device behavior help identify signs of hijacking or unauthorized access.

• Real-time intelligence alerts enterprises before stolen credentials or tokens are used for fraud.

Memcyco enables enterprises to detect and block phishing and ATO attempts that rely on MitM techniques.
