Man in the Middle: Cyber Attack

A man in the middle (MITM) attack is a form of cyber attack where the attacker secretly relays and possibly alters communication between two parties who believe they are directly communicating with each other. The goal is to steal sensitive information.

What is Man in the Middle?

A man in the middle (MITM) attack is a form of cyberattack where the attacker secretly inserts themselves into a conversation between two parties and relays messages between them. The two parties believe they are communicating directly with each other, but in reality the attacker is eavesdropping on the conversation and possibly even modifying the messages.

The goal of an MITM attack is to steal valuable private information that is transmitted between the two victims, such as login credentials, financial data, or trade secrets. The attacker is invisible to the victims - they only see each other. This allows the attacker to gather information or impersonate one of the parties without being detected.

MITM attacks can be performed in different ways depending on the communication medium. On public WiFi networks, attackers can use spoofing techniques to trick victims into connecting to a malicious hotspot controlled by the attacker instead of the legitimate network. On the broader internet, attackers may exploit vulnerabilities in cryptographic protocols to position themselves in the flow of traffic and intercept communications.

Common defenses against MITM attacks include encrypting network traffic with secure protocols like TLS that authenticate all parties, installing VPNs to route traffic through secured channels, using authentication mechanisms to verify identities, and installing endpoint and network security tools to detect malicious activity.
