• Wi-Fi Eavesdropping: Attackers set up rogue Wi-Fi hotspots to capture data from unsuspecting users.
• Session Hijacking: The attacker steals cookies from a user session to gain unauthorized access to an application.

Dangers of MITM Attacks

• Unauthorized purchases and identity theft are among the most common consequences of successful MITM attacks.
• Data breaches resulting from MITM attacks can have severe reputational and financial impacts on organizations.

Detection and Prevention Strategies

• Use encryption protocols like HTTPS to secure data exchanges between users and applications.
• Employ strong authentication measures to ensure the identities of both parties involved in communication.
