An attack where the adversary secretly intercepts and potentially alters communication between two parties who believe they are talking directly to each other. Attackers position themselves between client and server using ARP spoofing, DNS hijacking, or rogue Wi-Fi access points to capture credentials and sensitive data.
MitM attacks threaten every network communication without proper encryption. Security engineers implement TLS, certificate pinning, and HSTS to prevent interception. Penetration testers perform MitM attacks on internal networks to demonstrate credential exposure. SOC analysts monitor for ARP spoofing and DNS anomalies that indicate active MitM activity.
